EnglishIdioms, Phrasal Verbs & Proverbs
The detective suddenly ______ a useful clue. Fill in with the right phrasal verb.
- a.gave in
- b.came across
- c.fill up
- d.fell down
Answer: (B) came across
"Come across" means to find or encounter something unexpectedly, which fits a detective stumbling upon a clue; "give in" means to surrender, and "fall down"/"fill up" don't fit the sense of discovery at all.
