One clear advantage of selling goods online is that smaller markets can be served without the seller needing to invest in high inventory costs. Recordings of classical music, for example, are increasingly hard to find at the larger music chains. Now the classical music lover can locate nearly any classical CD in print on the Internet.

In addition, forward-thinking artists without national followings have made their music available on personal sites or through services that provide the musicians with a more generous share of profits than that offered by the large record labels. For some, this has resulted in increased sales volume, greater return on investment, greater control of the product, and a more direct connection with their fan base.

Major orchestras and record labels have taken note, and have created websites where one can purchase individual tracks, full CDs, archival recordings, and even music exclusively made available for online downloads. Some symphony orchestras now include, with the price of admission to a concert, the right to download a recording of the concert afterward. Other services allow the listener unlimited streaming or downloading for a monthly fee.

One disadvantage of selling goods online is that smaller retailers can be crushed by large online retailers. Big corporations that sell online have access to more goods so that brings the cost of each item down exponentially. They place larger orders and can carry more varieties of products so they may be able to satisfy more customers.

Just about anything can be found online so it takes away the fun of the hunt. Digging through vintage record bins, combing through racks of clothing, or spending a day out shopping with friends is reduced to a few clicks online and waiting 3-5 business days for the package to arrive. Small businesses are losing foot traffic to their stores and facing declining sales when a big box store can beat their price with a cheaper imported good.

Musicians, for example, may have CDs to sell after a performance but when people can download the single song they like or it can be listened to on a streaming service the artist can lose out on those sales. Many artists don’t produce a tangible good anymore and just make their goods available for digital download or purchase.

Genetic investigations into the origins of human life most often focus on mitochondrial DNA. As opposed to nuclear DNA, mitochondrial DNA is transmitted only from the mother. This allows for the tracing of mutations that arise independently of changes that occur because of the combining of the mother’s and father’s DNA. As useful as this is, the high mutation rate of mitochondrial DNA allows scientists to look at only relatively recent prehistory.

Text 2:

Nuclear DNA, on the other hand, has a low mutation rate, making it ideal for looking into the more distant past. Studying the nuclear DNA of fossils now shows a substantial decrease in population size in Europe and Asia approximately 50—80 thousand years ago. No such decrease happened in Africa. This supports the idea that migrants from Africa replaced all previous humans, and did not interbreed with earlier migrants.

"The Ruby-throated Hummingbird"

Geographical Range and Migration

The Ruby-throated Hummingbird is the sole representative of the hummingbird family in eastern North America. It is only a summer visitor in Canada and throughout the greater part of its range in the United States, excepting the southern portions of the Florida peninsula, where it winters to some extent. The majority of these birds migrate south, though, spending the winter in some of the Caribbean islands, while others pass through eastern Mexico into Central America. It usually arrives along our southern border in the latter part of March, rarely reaching the more northern States before the middle of May. It usually goes south again about the latter part of September, the males preceding the females, I believe, in both migrations. 

Appearance and Behavior

Ruby-throated Hummingbirds have iridescent green feathers on their backs and white feathers on their bellies. The male birds have a patch of red feathers on their throats, from which the species derives its name. Both male and female Ruby-throated Hummingbirds have relatively short tails and beaks and lack any crest of feathers on their heads.

Ruby-throated Hummingbirds’ flight is extremely swift, and the rapid motions of its wings in passing back and forth from one cluster of flowers to another causes a humming or buzzing sound, from which the numerous members of this family derive their name of hummingbirds. Notwithstanding the very small size of most of our hummers, they are all extremely pugnacious, especially the males, and are constantly quarreling and chasing each other, as well as other birds, some of which are many times larger than themselves. Mr. Manly Hardy writes me that he once saw a male Ruby-throat chase a Robin out of his garden. They are rarely seen entirely at rest for any length of time, and, when not busy preening its feathers, they dart about from one place to another. Although such a small, tiny creature, it is full of energy, and never seems to tire.

They seem to be especially partial to anything red. Mr. Manly Hardy writes: "I was once camping on one of the many islands along the coast of Maine during a dense fog, which had held us prisoners for several days, as it was so thick that we could not find our way. We had been living on lobsters, and lots of their red shells lay near the fire in front of our tent, when suddenly a Hummer came out of the fog and darted down at the shells, moving from one to another, seemingly loath to leave them.”

What Do They Eat?

There appears to be considerable difference of opinion among various observers regarding the nature of the Ruby-throated Hummingbird’s food. Some contend that it consists principally of nectar sipped from flowers, as well as the sweet sap of certain trees. Others, myself included, believe that they subsist mainly on minute insects and small spiders, the latter forming quite an important article of food with them. Mr. Edwin H. Eames, of Bridgeport, Connecticut, mentions finding sixteen young spiders of uniform size in the throat of a young Hummingbird which was about two days old.

Mr. W. N. Clute, of Binghamton, New York, writes: "The swamp thistle, which blooms in August, seems to have great attractions for the Ruby-throated Hummingbirds. I have seen more than a hundred birds about these plants in the course of an hour. Since it has been stated that the bee gets pollen but not honey from the thistle, it would appear that these birds visit these flowers for insects. There is scarcely a flower that contains so many minute insects as a thistle head. Examine one with a lens and it will be found to contain many insects that can hardly be seen with the unaided eye, and if the Ruby-throat eats insects at all, these are the ones it would take; and because the larger ones remained the observer might conclude that none were eaten.” I could quote considerable more testimony showing that the Hummingbirds live to a great extent on minute spiders and insects, but consider it unnecessary.

That our Hummingbirds live to some extent on the sap of certain trees is undoubtedly true, but that they could exist for any length of time on such food alone is very questionable. They are particularly fond of the sap of the sugar maple, and only slightly less so of that of a few other species of trees. They are also fond of the nectar secreted in many flowers. While stationed at the former cavalry depot at St. Louis, Missouri, in 1873-74, I occupied a set of quarters that were completely overrun with large trumpet vines. When these were in bloom, the place fairly swarmed with Ruby-throats. They were exceedingly inquisitive, and often poised themselves before an open window and looked in my rooms full of curiosity, their bright little eyes sparkling like black beads. I have caught several, while busily engaged sipping nectar in these large, showy flowers, by simply placing my hand over them, and while so imprisoned they never moved, and feigned death, but as soon as I opened my hand they were off like a flash.

Which of the following excerpts contains a claim that is NOT supported by any evidence whatsoever in the passage?

Adapted from “Theodore Roosevelt the Rancher.” National Park Service. U.S. Department of the Interior, n.d. Web. 1 July 2016. <https://www.nps.gov/thro/learn/historyculture/theodore-roosevelt-the-rancher.htm>.

Theodore Roosevelt originally came to Dakota Territory in 1883 to hunt bison. The locals showed little interest in helping this eastern tenderfoot. The promise of quick cash, however, convinced Joe Ferris—a 25-year-old Canadian living in the Badlands—to act as Roosevelt's hunting guide.

Through terrible weather and awful luck, Roosevelt showed a determination which surprised his exasperated hunting guide. Finding a bison proved difficult; most of the herds had been slaughtered in recent years by commercial hunters. When they were not sleeping outdoors, Roosevelt and Ferris used the small ranch cabin of Gregor Lang as a base camp. Evenings at Lang's ranch saw an exhausted Ferris falling asleep to conversations between Roosevelt and their host. Spirited debates on politics gave way to discussions about ranching, and Roosevelt became interested in raising cattle in the Badlands.

Cattle ranching in Dakota was a boom business in the 1880s. With the northern plains recently devoid of bison, cattle were being driven north from Texas to feed on the nutritious grasses. The Northern Pacific Railroad offered a quick route to eastern markets without long drives that reduced the quality of the meat. Entrepreneurs like the Marquis de Morès were bringing money and infrastructure to the region. The opportunity struck Roosevelt as a sound business opportunity.

With Roosevelt's interest sparked, he entered into business with his guide's brother, Sylvane Ferris, and Bill Merrifield, another Dakota cattleman. Roosevelt put down an initial investment of $14,000—significantly more than his annual salary. Roosevelt returned to New York with instructions for Ferris and Merrifield to build the Maltese Cross Cabin. His investment was not purely for business; Roosevelt saw it as a chance to immerse himself in a western lifestyle he had long romanticized.

According to the passage, what were the two major motives Roosevelt had in investing in a cattle ranch?

Archaeologists working in two recently discovered limestone caves in Sarawak, Malaysia have found a collection of 51 paintings estimated to be 6,000 to 12,000 years old. The paintings are unusual in their medium, manner of display, and subject matter. These are not simply wall or ceiling paintings. Stones—some as small as notebooks, some as large as doors—have been chipped and otherwise shaped to form rough canvases on which are painted individual works.

Some of the pieces are stacked, while others are arranged upright in an overlapping pattern so that one can “flip through” the smaller pieces in the collection with relative ease. Hunters, warriors, and hunted animals, the typical subjects of cave art, are largely absent from these works. Instead, domestic scenes are represented, including food preparations, family meals, and recreational activities.

Though no tools have been found in the area, the fineness of the lines suggests the use of sophisticated animal-hair brushes. Gypsum, manganese, malachite, and other minerals were painstakingly ground and mixed with binding materials such as vegetable and animal oils to form the paints. One probable reason for the high level of artistry is that the paintings may have been produced in the open air, where the light was good, and then brought into the cave.

However, it is the purpose of the paintings that is the most curious. Most interestingly, it may be that the collection represents a sort of family tree. A number of the paintings appear to feature some of the same people, and it is tempting to think of these works as family portraits. Indeed, one figure, seen as a child with a mark on its forehead—the stone has actually been chipped away to represent the mark—is shown in other paintings as a young person and as an adult with the same mark.

Where in the text do you find evidence to support the author’s claim regarding the purpose of the paintings?

Marian Anderson was a world-class singer. By the year 1939, Marian had sung for people around the world, including kings and presidents. Her dream was to sing at Constitution Hall but in her mind, she viewed it as something that would never happen. The owners, the Daughters of the American Revolution (DAR), would not allow her to sing because she was African-American.

Marian was used to dealing with people who only saw her for her skin color. When she was younger she applied to become a student at a music school. She was denied entrance because of her race. In the early 1900s when Marian was beginning her singing career segregation was still keeping African-American people from achieving their goals and dreams.

Marian performed in 1925 in a voice contest in New York and won. She was able to sing with the New York Philharmonic! She thought doors were going to start opening for her in the United States but instead, people foolishly turned her away. Marian traveled to Europe in 1928 and she became quite popular.

In 1939, she returned to the United States but she was still subject to the cruelty and unfairness of racism and segregation. When Marian attempted to sing at Constitution Hall the DAR had many excuses for why she couldn’t perform. They tried telling her the dates weren’t available or they weren’t booking. Eventually, they told Marian the truth, she couldn’t perform because they only allowed white musicians.

This rejection inspired thousands of people to rally together against the horrible segregation laws that prevented so many from hearing Marian’s beautiful voice. First Lady Eleanor Roosevelt resigned from the DAR and publicly shamed them for their treatment of African-America performers. Mrs. Roosevelt and her staff arranged a concert at the Lincoln Memorial for Marian. Seventy-five thousand people attended and stood against discrimination.

After the DAR incident, Marian took a stand and refused to sing for segregated crowds. She finally achieved her dream of singing at Constitution Hall when the DAR reversed its policy on allowing African-American performers. In 1964 Marian retired from performing and The Civil Rights Act was signed. She along with other brave activists took a stand and created lasting change against racism and segregation in the United States.

Which of the following claims is not supported by evidence?
