Answers

Answer: D) If we could get at least twenty-five percent of the entire senior class to agree with the change of venue for prom.

Explanation: Every other sentence is more or less a cause and effect. Mom screamed was the effect and the cause was due to the horror movie in front of her kids. The room goes silent, also an effect. Due to the principle with a clipboard. The final sentence has an effect, but no reason or cause. Therefore, it is incomplete.

How are "in Just-" and "July" different in terms of their language? The word choice in "July" reflects the slow, meandering rhythms of summer, while the word choice in "in Just-" reflects the slow, meandering rhythms of spring. The word choice in in Just- enhances its meaning as a poem about children, while the word choice in July reflects that it is a poem about middle age. In "July," word choice reflects the slow pace and laziness of summer, while the word choice in "in Just-" suggests the youth and vigor of spring. The word choice in July creates an unpredictable rhythm, which suggests the fleeting nature of summer, while the predictable rhythm of "in Just-" reflects the rebirth that occurs in spring.
