Another means of preserving health to be attended to is the having a constant supply of fresh air in your bedchamber. It has been a great mistake, the sleeping in rooms exactly closed and the beds surrounded by curtains. No outward air that may come in to you is so unwholesome as the unchanged air, often breathed, of a close chamber. As boiling water does not grow hotter by long boiling if the particles that receive greater heat can escape, so living bodies do not putrefy if the particles, so fast as they become putrid, can be thrown off. Nature expels them by the pores of the skin and lungs, and in a free, open air they are carried off; but in a close room we receive them again and again, though they become more and more corrupt. A number of persons crowded into a small room thus spoil the air in a few minutes, and even render it mortal as the Black Hole at Calcutta. A single person is said to spoil only a gallon of air per minute, and therefore requires a longer time to spoil a chamberful; but it is done, however, in proportion, and many putrid disorders hence have their origin. It is recorded of Methuselah, who, being the longest liver, may be supposed to have best pre­served his health, that he slept always in the open air; for when he had lived five hundred years an angel said to him: "Arise, Methuselah, and build thee a house, for thou shalt live yet five hundred years longer." But Methuselah answered and said: "If I am to live but five hundred years longer, it is not worth while to build me an house; I will sleep in the air, as I have been used to do." Physicians, after having for ages contended that the sick should not be indulged with fresh air, have at length discovered that it may do them good. It is therefore to be hoped that they may in time discover likewise that it is not hurtful to those who are in health, and that we may then be cured of the aerophobia that at present distresses weak minds, and makes them choose to be stifled and poisoned rather than leave open the window of a bedchamber or put down the glass of a coach.

Confined air, when saturated with perspirable matter, will not receive more, and that matter must remain in our bodies and occasion diseases; but it gives us some previous notice of its being about to be hurtful by producing certain uneasiness, slight indeed at first, such as with regard to the lungs is a trifling sensation and to the pores of the skin a kind of restlessness which is difficult to describe, and few that feel it know the cause of it. But we may recollect that sometimes, on waking in the night, we have, if warmly covered, found it difficult to get asleep again. We turn often, without finding repose in any position. This fidgetiness (to use a vulgar expression for want of a better) is occasioned wholly by uneasiness in the skin, owing to the retention of the perspirable matter, the bedclothes having received their quantity, and being saturated, refusing to take any more. To become sensible of this by an experiment, let a person keep his position in the bed, throw off the bedclothes, and suffer fresh air to approach the part uncovered of his body; he will then feel that part suddenly refreshed, for the air will immediately relieve the skin by receiving, licking up, and carrying off the load of perspirable matter that approaches the warm skin, in receiving its part of that vapor, receives therewith a degree of heat that rarefies and renders it lighter, by cooler and therefore heavier fresh air, which for a moment supplies its place, and then, being likewise changed and warmed, gives way to a succeeding quantity.

Franklin most likely uses the passive voice in the phrase "a single person is said to spoil only a gallon of air per minute" because __________.

Adapted from "A Scandal in Bohemia" in Adventures of Sherlock Holmes by Sir Arthur Conan Doyle (1892 ed.)

To Sherlock Holmes she is always the woman. I have seldom heard him mention her under any other name. In his eyes she eclipses and predominates the whole of her sex. It was not that he felt any emotion akin to love for Irene Adler. All emotions, and that one particularly, were abhorrent to his cold, precise, but admirably balanced mind. He was, I take it, the most perfect reasoning and observing machine that the world has seen, but as a lover he would have placed himself in a false position. He never spoke of the softer passions, save with a gibe and a sneer. They were admirable things for the observer—excellent for drawing the veil from men’s motives and actions. But for the trained reasoner to admit such intrusions into his own delicate and finely adjusted temperament was to introduce a distracting factor which might throw a doubt upon all his mental results. Grit in a sensitive instrument, or a crack in one of his own high-power lenses, would not be more disturbing than a strong emotion in a nature such as his. And yet there was but one woman to him, and that woman was the late Irene Adler, of dubious and questionable memory.

I had seen little of Holmes lately. My marriage had drifted us away from each other. My own complete happiness, and the home-centred interests which rise up around the man who first finds himself master of his own establishment, were sufficient to absorb all my attention, while Holmes, who loathed every form of society with his whole Bohemian soul, remained in our lodgings in Baker Street, buried among his old books, and alternating from week to week between drugs and ambition, the drowsiness of drugs, and the fierce energy of his own keen nature. He was still, as ever, deeply attracted by the study of crime, and occupied his immense faculties and extraordinary powers of observation in following out those clues, and clearing up those mysteries which had been abandoned as hopeless by the official police. From time to time I heard some vague account of his doings: of his summons to Odessa in the case of the Trepoff murder, of his clearing up of the singular tragedy of the Atkinson brothers at Trincomalee, and finally of the mission which he had accomplished so delicately and successfully for the reigning family of Holland. Beyond these signs of his activity, however, which I merely shared with all the readers of the daily press, I knew little of my former friend and companion.

One night—it was on the twentieth of March, 1888—I was returning from a journey to a patient (for I had now returned to civil practice), when my way led me through Baker Street. As I passed the well-remembered door, which must always be associated in my mind with my wooing, and with the dark incidents of the mystery that was solved there, I was seized with a keen desire to see Holmes again, and to know how he was employing his extraordinary powers. His rooms were brilliantly lit, and, even as I looked up, I saw his tall, spare figure pass twice in a dark silhouette against the blind. He was pacing the room swiftly, eagerly, with his head sunk upon his chest and his hands clasped behind him. To me, who knew his every mood and habit, his attitude and manner told their own story. He was at work again. He had risen out of his drug-created dreams and was hot upon the scent of some new problem. I rang the bell and was shown up to the chamber which had formerly been in part my own.

His manner was not effusive. It seldom was; but he was glad, I think, to see me. With hardly a word spoken, but with a kindly eye, he waved me to an armchair, threw across his case of cigars. Then he stood before the fire and looked me over in his singular introspective fashion.

From the narrator's perspective, Sherlock Holmes can best be described as __________.

Adapted from On the Origin of Species by Charles Darwin (1859)

How will the struggle for existence, discussed too briefly in the last chapter, act in regard to variation? Can the principle of selection, which we have seen is so potent in the hands of man, apply in nature? I think we shall see that it can act most effectually. Let it be borne in mind in what an endless number of strange peculiarities our domestic productions, and, in a lesser degree, those under nature, vary; and how strong the hereditary tendency is. Under domestication, it may be truly said that the whole organization becomes in some degree plastic. Let it be borne in mind how infinitely complex and close-fitting are the mutual relations of all organic beings to each other and to their physical conditions of life. Can it, then, be thought improbable, seeing that variations useful to man have undoubtedly occurred, that other variations useful in some way to each being in the great and complex battle of life, should sometimes occur in the course of thousands of generations? If such do occur, can we doubt (remembering that many more individuals are born than can possibly survive) that individuals having any advantage, however slight, over others, would have the best chance of surviving and of procreating their kind? On the other hand, we may feel sure that any variation in the least degree injurious would be rigidly destroyed. This preservation of favorable variations and the rejection of injurious variations, I call Natural Selection. Variations neither useful nor injurious would not be affected by natural selection, and would be left a fluctuating element, as perhaps we see in the species called polymorphic.

We shall best understand the probable course of natural selection by taking the case of a country undergoing some physical change, for instance, of climate. The proportional numbers of its inhabitants would almost immediately undergo a change, and some species might become extinct. We may conclude, from what we have seen of the intimate and complex manner in which the inhabitants of each country are bound together, that any change in the numerical proportions of some of the inhabitants, independently of the change of climate itself, would most seriously affect many of the others. If the country were open on its borders, new forms would certainly immigrate, and this also would seriously disturb the relations of some of the former inhabitants. Let it be remembered how powerful the influence of a single introduced tree or mammal has been shown to be. But in the case of an island, or of a country partly surrounded by barriers, into which new and better adapted forms could not freely enter, we should then have places in the economy of nature which would assuredly be better filled up, if some of the original inhabitants were in some manner modified; for, had the area been open to immigration, these same places would have been seized on by intruders. In such case, every slight modification, which in the course of ages chanced to arise, and which in any way favoured the individuals of any of the species, by better adapting them to their altered conditions, would tend to be preserved; and natural selection would thus have free scope for the work of improvement.

Adapted from "The Sisters" in Dubliners by James Joyce (1914)

There was no hope for him this time: it was the third stroke. Night after night I had passed the house (it was vacation time) and studied the lighted square of window, and night after night I had found it lighted in the same way, faintly and evenly. If he was dead, I thought, I would see the reflection of candles on the darkened blind, for I knew that two candles must be set at the head of a corpse. He had often said to me, "I am not long for this world," and I had thought his words idle. Now I knew they were true. Every night as I gazed up at the window I said softly to myself the word “paralysis.” It had always sounded strangely in my ears, like the word “gnomon” in the Euclid and the word “simony” in the Catechism. But now it sounded to me like the name of some maleficent and sinful being. It filled me with fear, and yet I longed to be nearer to it and to look upon its deadly work.

Old Cotter was sitting at the fire, smoking, when I came downstairs to supper. While my aunt was ladling out my stirabout he said, as if returning to some former remark of his:

"No, I wouldn't say he was exactly . . . but there was something queer . . . there was something uncanny about him. I'll tell you my opinion . . ."

He began to puff at his pipe, no doubt arranging his opinion in his mind. Tiresome old fool! When we knew him first he used to be rather interesting, talking of faints and worms, but I soon grew tired of him and his endless stories about the distillery.

"I have my own theory about it," he said. "I think it was one of those . . . peculiar cases . . . But it's hard to say . . ."

He began to puff again at his pipe without giving us his theory. My uncle saw me staring and said to me:

"Well, so your old friend is gone, you'll be sorry to hear."

"Who?" said I.

"Father Flynn."

"Is he dead?"

"Mr. Cotter here has just told us. He was passing by the house."

I knew that I was under observation, so I continued eating as if the news had not interested me. My uncle explained to old Cotter.

"The youngster and he were great friends. The old chap taught him a great deal, mind you; and they say he had a great wish for him."

"God have mercy on his soul," said my aunt piously.

Old Cotter looked at me for a while. I felt that his little beady black eyes were examining me, but I would not satisfy him by looking up from my plate. He returned to his pipe and finally spat rudely into the grate.

The narrator is __________ by Old Cotter’s speech because __________.

Adapted from Once on a Time by A. A. Milne (1922)

The Princess was still puzzled. "But I'm grown up," she said. "I don't want a mother so much now."

The King turned his flagon round and studied the other side of it.

"A mother's—er—tender hand," he said, "is—er—never——" and then the outrageous thing happened.

It was all because of a birthday present to the King of Barodia, and the present was nothing less than a pair of seven-league boots. The King being a busy man, it was a week or more before he had an opportunity of trying those boots. Meanwhile he used to talk about them at meals, and he would polish them up every night before he went to bed. When the great day came for the first trial of them to be made, he took a patronizing farewell of his wife and family, ignored the many eager noses pressed against the upper windows of the palace, and sailed off. The motion, as perhaps you know, is a little disquieting at first, but one soon gets used to it. After that it is fascinating. He had gone some two thousand miles before he realized that there might be a difficulty about finding his way back. The difficulty proved at least as great as he had anticipated. For the rest of that day he toured backwards and forwards across the country, and it was by the merest accident that a very angry King shot in through an open pantry window in the early hours of the morning. He removed his boots and went softly to bed.

It was, of course, a lesson to him. He decided that in the future he must proceed by a recognized route, sailing lightly from landmark to landmark. Such a route his geographers prepared for him—an early morning constitutional, of three hundred miles or so, to be taken ten times before breakfast. He gave himself a week in which to recover his nerve and then started out on the first of them.

Adapted from A Tramp Abroad by Mark Twain (1880)

One day it occurred to me that it had been many years since the world had been afforded the spectacle of a man adventurous enough to undertake a journey through Europe on foot. After much thought, I decided that I was a person fitted to furnish to mankind this spectacle. So I determined to do it. This was in March, 1878.

I looked about me for the right sort of person to accompany me in the capacity of agent, and finally hired a Mr. Harris for this service.

It was also my purpose to study art while in Europe. Mr. Harris was in sympathy with me in this. He was as much of an enthusiast in art as I was, and not less anxious to learn to paint. I desired to learn the German language; so did Harris.

Toward the middle of April we sailed in the Holsatia, Captain Brandt, and had a very pleasant trip, indeed.

After a brief rest at Hamburg, we made preparations for a long pedestrian trip southward in the soft spring weather, but at the last moment we changed the program, for private reasons, and took the express-train.

We made a short halt at Frankfort-on-the-Main, and found it an interesting city. I would have liked to visit the birthplace of Gutenburg, but it could not be done, as no memorandum of the site of the house has been kept. So we spent an hour in the Goethe mansion instead. The city permits this house to belong to private parties, instead of gracing and dignifying herself with the honor of possessing and protecting it.

Frankfort is one of the sixteen cities which have the distinction of being the place where the following incident occurred. Charlemagne, while chasing the Saxons (as he said), or being chased by them (as they said), arrived at the bank of the river at dawn, in a fog. The enemy were either before him or behind him; but in any case he wanted to get across, very badly. He would have given anything for a guide, but none was to be had. Presently he saw a deer, followed by her young, approach the water. He watched her, judging that she would seek a ford, and he was right. She waded over, and the army followed. So a great Frankish victory or defeat was gained or avoided; and in order to commemorate the episode, Charlemagne commanded a city to be built there, which he named Frankfort—the ford of the Franks. None of the other cities where this event happened were named for it. This is good evidence that Frankfort was the first place it occurred at.

Adapted from Jude the Obscure by Thomas Hardy (1895)

He sounded the clacker till his arm ached, and at length his heart grew sympathetic with the birds' thwarted desires. They seemed, like himself, to be living in a world which did not want them. Why should he frighten them away? They took upon more and more the aspect of gentle friends and pensioners—the only friends he could claim as being in the least degree interested in him, for his aunt had often told him that she was not. He ceased his rattling, and they alighted anew.

"Poor little dears!" said Jude, aloud. "You shall have some dinner—you shall. There is enough for us all. Farmer Troutham can afford to let you have some. Eat, then my dear little birdies, and make a good meal!"

They stayed and ate, inky spots on the nut-brown soil, and Jude enjoyed their appetite. A magic thread of fellow-feeling united his own life with theirs. Puny and sorry as those lives were, they much resembled his own.

His clacker he had by this time thrown away from him, as being a mean and sordid instrument, offensive both to the birds and to himself as their friend. All at once he became conscious of a smart blow upon his buttocks, followed by a loud clack, which announced to his surprised senses that the clacker had been the instrument of offense used. The birds and Jude started up simultaneously, and the dazed eyes of the latter beheld the farmer in person, the great Troutham himself, his red face glaring down upon Jude's cowering frame, the clacker swinging in his hand.

"So it's 'Eat my dear birdies,' is it, young man? 'Eat, dear birdies,' indeed! I'll tickle your breeches, and see if you say, 'Eat, dear birdies' again in a hurry! And you've been idling at the schoolmaster's too, instead of coming here, ha'n't ye, hey? That's how you earn your sixpence a day for keeping the rooks off my corn!"

Adapted from Aristotle's Politics: A Treatise on Government by Aristotle (trans. Ellis 1895)

Now with respect to these honors, which he proposes to bestow on those who can give any information useful to the community, this, though very pleasing in speculation, is what the legislator should not settle, for it would encourage informers, and probably occasion commotions in the state. And this proposal of his gives rise also to further conjectures and inquiries; for some persons have doubted whether it is useful or hurtful to alter the established law of any country, if even for the better.  We cannot immediately determine upon what he here says, whether it is advantageous to alter the law or not. We know, indeed, that it is possible to propose to new model both the laws and government as a common good.  Since we have mentioned this subject, it may be very proper to enter into a few particulars concerning it, for it contains some difficulties, as I have already said, and it may appear better to alter them, since it has been found useful in other sciences.

Based on his proposed continued discussion, what can we infer about the author's manner of reasoning in this book?
