Answer:
Hello there, what you got wrong was you didn’t circle the prepositions.
Explanation:
For example, let’s take the last sentence in you paper,
“Then they place additional rows on top.”
On is a preposition. The prepositional phrase always starts with the prepsoition, so the phrase is “on top.”
For the 1st one, during is a preposition, so during their travels is correct.
Thank you and have a wonderful day/night!
