Question 45: Mark the letter A, B, C, or D on your answer sheet to indicate the undelined part that needs correction in each of the following questions: Little he knows (A) about (B) the surprise that (C) awaited (D) him when he arrived there.
We have: little (almost, very little) at the beginning of a sentence, the following clause must be inverted. So: he knows => did he know. (there is “awaited” in the latter – simple past tense.)
Translation: He knew almost nothing of the surprise that awaited his return there.
