Question 41: She wishes she didn't send her the candy yesterday because she's on diet.
Answer: A. didn't send
(Correct form: "hadn't sent" to match the past perfect construction needed with "wishes" for something that did not happen in the past.)

Question 42: The children enjoyed taking to the zoo when they had free time.

(Correct form: "enjoyed going" or "enjoyed the trip" as "taking" is incorrect in this context.)
