Choose the words that best complete the sentence.
Although the instructions looked ______ at first, they proved quite ______ once the teacher had worked through an example, and every group finished early.
A. simple … easy
B. confusing … straightforward
C. complicated … baffling
D. clear … puzzling
- 'Although' is a contrast signal, so the two blanks must have opposite senses. This removes A and C, where both words point the same way.
- Clue for the second blank: after one example, 'every group finished early', so the instructions turned out to be easy.
- The second blank is positive and the first is negative. D has them the wrong way round.
- B fits both: looked confusing at first, proved straightforward in the end.
Answer: B. confusing … straightforward
