I would say A for question 4
She didn't want to be the receiver of memories because they made her very depressed and she felt empty so she asked to be released so she doesn't have to deal with more horrible memories, they made her feel alone and that there was so much sad times. She had to face things she has never felt before and it was too much so death was the answer.
Since misery and depression are both sad/bad kinds of feelings, then we have to find a pair of words that have the same kind of feeling in order to complete this analogy. The correct answer should be melancholy and boredom.
