Question

choose the sentence in this excerpt that supports the claim that daydreaming could be harmful. our ability to multitask in this way is useful, but it also has drawbacks. daydreaming minds are disconnected from the outside world and turned inward. so on that walk home from school, it would be hard for you to remember later anything you saw while you were daydreaming. it would also be harder for you to avoid sudden, unexpected sources of danger, like a tree root that causes you to trip and fall flat on your face.

Explanation:

To support the claim that daydreaming could be harmful, we look for a sentence that shows negative consequences of daydreaming. The sentence "It would also be harder for you to avoid sudden, unexpected sources of danger, like a tree root that causes you to trip and fall flat on your face" describes a harmful outcome (tripping and falling due to inability to avoid danger) resulting from daydreaming.

Answer:

It would also be harder for you to avoid sudden, unexpected sources of danger, like a tree root that causes you to trip and fall flat on your face.
