Answer:
I believe the answers are:
I've applied to three universities----> It deserves how many times it happened
I've seen this film before----> It happened at an unspecified time in the past
Explanation:
The word 'three' is explaining to us that she/he had applied many times.
'Seen before' tells us that it happened in the past but it does not give us a specific time, day or date in the sentence.
The verb is "trudged".
It's the past simple form of the verb "to trudge" which is a type of a walk, usually slow and heavy as if you have weights on yourself.
