Context: This is a comprehension check question for a text which basically says that people are quick to forget information unless they study/review it several times. We have to answer whether the sentence below is true or false.
The sentence: People remember most of what they have studied for many days.
- People remember (for many days) most of what they have studied.
- People remember most of what they have studied (for many days).
My initial answer is FALSE, if the adverbial phrase modifies the verb "remember". But on second thought, can it also modify the verb "have studied"? If so, wouldn't the answer be TRUE?
