1. Correct Answer: D
解析:
Clue: ‘however’ indicates a contradictory statement, and therefore we need opposite ideas in the two halves of the sentence. So, Wegener’s theory is unchallenged(everyone accepts it); however he was treated with disdain (contempt). Also the word ‘outsider’ in the sentence indicates that the second blank will have to be a negative word. (approbation = approval; reverence = respect)


2.Correct Answer: E
解析:
Clue: ‘as ever’ indicates that things have not changed, so the two halves of the sentence need to say similar things. So, if the revolution has not lost its steam, it will be going on as strongly as before. Therefore rages is the best word. Also the word ‘fiercely’ indicates that we need a strong word. (trudges = walks as though tired; meanders = wanders; ambles = walks aimlessly)


3. Correct Answer: D
解析:
Clue: The second half of the sentence is talking about language, and it is amplifying what has been said before the semicolon. Therefore, the first blank needs to be about language and ‘jargon’ is specialized language used in a profession.


4. Correct Answer: C
解析:
Clue: He ‘spoke very little’ and so he uses few words. Therefore, taciturn is the best word. (garrulous = talkative; equivocal = ambiguous; gregarious = sociable)


5. Correct Answer: D
解析:
Clue: The sentence structure suggests that if biological clocks are a great advantage, then most organisms would possess them. [Or, if they are not an advantage, then organisms will not have them.] Therefore, the obvious value, leads us to expect that organisms possess them. (meager = small, slight; eschew = shun, avoid; ambivalent = ambiguous)
