Because we know that the forecast predicted snow storms, we can infer that it also predicted cold weather. So, we need to pick out an answer choice for the first blank that means something like "cold." Either "frigid," "chilly," or "icy" could be potentially correct. For the second blank, we need to pick out a word that describes the action of wearing a scarf, hat, and mittens if one knows the weather is going to be cold and snowy. Since wearing those items is a good idea, either "smart," "necessary," or "prudent" ("acting with or showing care and thought for the future") could be potentially correct. Of the possible words that we've identified as potentially correct for each blank, only "frigid" and "prudent" appear in the same answer choice, so the correct answer is "frigid . . . prudent."

We can infer from the sentence that while cell phones were rare in the 1990's, they are no longer rare, so we know that we need to find an adjective for the first blank that means something like "common." Either "ubiquitous" ("present, appearing, or found everywhere") or "pervasive" ("spreading widely throughout an area or a group of people") could work. For the second blank, we know that the individuals we need to describe choose "to be in almost constant communication with their friends," so we can infer that we need to find an adjective that means something like "social" or "talkative." "Gregarious," which means "fond of company; sociable" seems like a good answer choice, as does "garrulous," which means "talkative." Of the possible words that we've identified as potentially correct for each blank, only "ubiquitous" and "gregarious" appear in the same answer choice, so the correct answer is "ubiquitous . . . gregarious."

We can infer that for the first blank, we need to pick out a word that describes how the students might receive someone who didn't speak all day. "Garrulous," an adjective meaning "talkative," is definitely not the correct answer, but either "mysterious" or "enigmatic" ("difficult to interpret or understand; mysterious") could be correct. For the second blank, we need to pick out a word that means something like "always," "often," or "very," because we can infer that the new student is, in fact, shy. Either "extremely," "sometimes," or"acutely" ("intensely, with reference to something unpleasant or unwelcome") could be potentially correct. Of the possible words that we've identified as potentially correct for each blank, only "enigmatic" and "acutely" appear in the same answer choice, so the correct answer is "enigmatic . . . acutely."

For the first blank, we need to pick out an adjective that means something like "involving individual opinions and personal feelings." So, either "subjective" (" based on or influenced by personal feelings, tastes, or opinions") or "qualitative" ("relating to, measuring, or measured by the quality of something rather than its quantity") could be potentially correct. For the second blank, we need to pick out an adjective that means something like "based on facts, theories, and laws." Either "objective" ("not influenced by personal feelings or opinions in considering and representing facts") or "quantitative" ("relating to, measuring, or measured by the quantity of something rather than its quality") could be potentially correct. Of the possible words that we've identified as potentially correct for each blank, only "subjective" and "objective" appear in the same answer choice in the correct order, so the correct answer is "subjective . . . objective."

"Grandiose" means extravagant or ambitious. "Burgeoning" means prospering or expanding. "Nonchalant" means easygoing or laid back. "Mellifluous" means smooth and sweet-sounding. "Haughty" means arrogant or snobbish. "Germane" means appropriate or applicable. "Listless" means spiritless or without energy. "Inchoate" means undeveloped or beginning. "Perfunctory" means automatic or unthinking. "Obscure" means not easily understood or ambiguous.

For the first blank, we can infer that because the explorer faced "dangerous jungles filled with vicious predators, poisonous snakes and tropical diseases," she must have been pretty brave, so we need to pick out an answer choice that is an adjective and means something like "brave" to describe her. Either "intrepid" ("fearless; adventurous (often used for rhetorical or humorous effect)") or "courageous" ("not deterred by danger or pain; brave") could be potentially correct. For the second blank, we know that something about the volume's length is "surprising," and that it "only had about thirty pages when most people expected hundreds," so we can infer that we need to pick out an answer choice that is an adjective and means something like "short." Either "brief" ("concise in expression; using few words") or "concise" ("giving a lot of information clearly and in a few words; brief but comprehensive") could be potentially correct. Of the possible words that we've identified as potentially correct for each blank, only "intrepid" and "concise" appear in the same answer choice, so the correct answer is "intrepid . . . concise."

We can infer that because the biology student "was soon corrected when she learned . . . that many of the [zoo's snakes] were extremely poisonous," she must have initially believed them to not be poisonous. So, we need to pick out an adjective for the second blank that means something like "not poisonous." Either "benign" (" not causing harm or damage") or "harmless" ("not able or likely to cause harm") could be potentially correct. Working backwards, then, we might characterize the biology student as uninformed and guess that she is inexperienced if she initially thought that all the snakes in the zoo were not poisonous, so we need to pick out an adjective for the first blank that means something like "uninformed" or "inexperienced." Either "naive" (" showing a lack of experience, wisdom, or judgment" when used of a person or action) or "inexperienced" ("having little knowledge or experience of a particular thing") could be potentially correct. Of the potentially correct answers we've identified, only "naïve" and "benign" appear in a single answer choice, so "naïve . . . benign" is the correct answer.

Considering the first blank, we know that Harry "hadn't expected to place in the top five" in the Science Fair, but ended up "com[ing] in second," so we can infer that Harry was very happy about this and that we need to pick out an adjective to describe him that means something like "very happy." Either "euphoric" ("characterized by or feeling intense excitement and happiness") or "ecstatic" ("feeling or expressing overwhelming happiness or joyful excitement") could be correct. For the second blank, we know that George "had expected to win first prize" but "came in fourth," so we can infer that he wasn't so happy with that turnout. So, we need to pick out another word that means something like "happy." Either "gleeful" ("exuberantly or triumphantly joyful") or "pleased" ("feeling or showing pleasure and satisfaction, especially at an event or a situation") could be correct. Of the possible words that we've identified as potentially correct for each blank, only "euphoric" and "gleeful" appear in the same answer choice, so the correct answer is "euphoric . . . gleeful."

The first blank of this sentence is contrasted with the subordinate clause "taken as  a whole." The general idea is that, while Greta was certain of something concerning the whole reasoning, she was not certain about any given parts of it. That is, she was not certain regarding any specific errors. The word "specific" means distinct or identifiable; it is often contrasted to "general" or "generic." The second blank is best understood in relation to the word "errors in George's reasoning." While she was not certain about any specific parts, she was sure that the reasoning had errors. Thus, among the options provided, the best answer is "illogical," which means "having the character of poor, incorrect reasoning."

The adjective that we choose for the first blank needs to describe texts and have a positive connotation since the intern was hired for her ability to write good explanations. "Lucid" (which means expressed clearly; easy to understand) and "articulate" (which means fluent and coherent when referring to a person's writing) are each good choices for the first blank. For the second blank, we need to pick an adjective that has something to do with the art works' beauty. Choosing between "aesthetic" (concerned with beauty or the appreciation of beauty) and "empirical" (having to do with observation or experience rather than theory), "aesthetic" is the better choice, so the answer is "lucid . . . aesthetic."
