The parents were protesting and complaining abut the speech, which means that some sort of bad language was used and they were upset about it. The choices that could fit in the first blank are profane and explicit, but only profane's match (horrified) shows that the audience did not like the speech.

The implication of the sentence is that the speakers overpowered John’s voice to such an extend that those who were next to him could not hear him at all. On this count, his voice could be considered “inaudible,” meaning, “unable to be heard.” The “audible” portion of “inaudible,” is derived from the Latin root for “to hear,” and is found in other English words like “audio,” “audience,” and “auditorium.” The word render has a number of meanings. Here, it means “to make.”

For the first blank, we need to pick out a verb that describes how one would mark a rune into a stone. Either "inscribing" ("writing or carving words or symbols on something, especially as a formal or permanent record") or "carving" could be correct. For the second blank, we need to pick out an adjective that means something like "able to be read" or "able to be understood." Either "legible" ("clear enough to read" and used with handwriting or print) or "readable" could be correct. Of the possible words that we've identified as potentially correct for each blank, only "inscribing" and "legible" appear in the same answer choice, so the correct answer is "inscribing . . . legible."

We can infer that because the con man commits a crime and then blames it on his associate, we need to pick out an adjective to describe him that means something like "not honorable." Either "ignoble" ("not honorable in character or purpose") or "dastardly" ("wicked and cruel") could be correct. For the second blank, we need to pick out a verb that means something like "fools" because we know that the police officer "arrest[s] the wrong man." Either "dupes" ("deceives; tricks") or "hoodwinks" ("deceives or tricks (someone") could be correct. Of the possible words that we've identified as potentially correct for each blank, only "ignoble" and "dupes" appear in the same answer choice, so the correct answer is "ignoble . . . dupes."

For the first blank, we know that the subject of our sentence tried to use the same vocabulary as her favorite author, but found it awkward, so we can guess that she tried to mimic his style, and we need to pick out a verb that means something like "mimic." Either "emulate" or "imitate" could be correct. For the second blank, we need to pick out an adjective that describes what kind of vocabulary would have been popular in the 1700s but awkward to use today. Either "archaic" ("very old or old-fashioned" or when used of a word or a style of language, "no longer in everyday use but sometimes used to impart an old-fashioned flavor") or "outdated" could be correct. Of the possible words that we've identified as potentially correct for each blank, only "emulate" and "archaic" appear in the same answer choice, so the correct answer is "emulate . . . archaic."

For the first blank, we know that the teacher gave "clearly explained directions," so we need to pick out an adjective that means something like "clearly explained." Either "explicit" ("stated clearly and in detail, leaving no room for confusion or doubt") or "straightforward" ("uncomplicated and easy to do or understand") could be correct. For the second blank, we need to pick out a word that means "get" or "sustain," because we know that the students who did not follow the teacher's instructions would "lose a few points off of their quiz" - in other words, sustain a small penalty. Either "incur" ("become subject to something unwelcome or unpleasant as a result of one's own behavior or actions") or "receive" could be potentially correct. Of the possible words that we've identified as potentially correct for each blank, only "explicit" and "incur" appear in the same answer choice, so the correct answer is "explicit . . . incur."

The clear contrast in this sentence is between an energetic disposition and one that is not. The best option for the second blank is “sedate” which means quiet or still (sometimes having the negative sense of “dull”). Since the word is modified (and hence qualified) by “rather,” it is fair to choose something like this, which generally fits, if not perfectly. To be sedate is related to the Latin for “to sit.” A “sedative” is a drug or medication that makes one calm or as though they were sitting still. Since Joseph became sedate, the low blood sugar condition must have drained him of his energy, that is, to have sapped him of his energy.

The second blank would be easier to fill in first, so we need to find a word that means difficult to understand. This could be either dense or complicated (because lucid means clear, morose means gloomy, and creative speech isn't always difficult). Next we'll fill in the first blank that shows that his students did not understand, or were confused. Enlighten would not work because the teacher would want to enlighten them with knowledge, so our answer is "disconcert . . . dense."

If a witness makes false or spurious statements about a crime, they keep justice from occurring; therefore, they impede justice.

The key expression is “approximated subgroups” to which the many elements are contrasted in the first half of the sentence. “Disparate” items are those that are differing to a degree that comparison becomes difficult (if not wholly impossible). It comes from Latin roots meaning “unequal,” reflected in the English word “disparity.” When something is gathered together, it is “aggregated,” a word related to words such as “segregated” (gathered into separate groups) and “congregation.” These are derived from the Latin for flock (“gregis”).
