Answer:
On, during, near, are the correct answers.
Explanation:
A preposition expresses a relation between one word and another one, or a word and a part of the sentence. There are different types, such as place, direction, and motion.
The first answer is "Juan left his wallet on top of the dresser." The object (the wallet) lays on the surface since the sentence says "top of the dresser", that's why on is correct.
Second one is "Lorna fell asleep during the television show and missed the ending," since it expresses that one action (fell asleep) happened while the other action was in progress, and then it continued.
Last one indicates a short distance (we can walk), so the correct answer is Sheryl’s house is near the park, so we can walk from there.
