Question

before cambria entered the arena to watch the speech, she decided to turn her cell phone off. cambrias decision wi help her
pay attention to the speaker.
prejudge the speaker
avoid jumping to conclusions.
research the speakers topic.

Explanation:

Turning off the cell phone reduces distractions. This allows Cambria to focus on the speaker. Prejudging the speaker (making assumptions before listening) is not related to turning off the phone. Avoiding jumping to conclusions (making hasty judgments) is about thinking critically during the speech, not phone - off action. Researching the speaker's topic would require using resources like a computer or books, not just turning off the phone.

Answer:

pay attention to the speaker.
