Question

how does mr. depalmas change in behavior reflect the shift in mood in the second section of american history? he becomes emotional and grief - stricken, showing a shift to a somber mood. he becomes a strict disciplinarian, showing a shift to a tense mood. he becomes a comforting figure to the students, showing a shift to a more sentimental mood. he becomes indifferent to his students, showing a shift to a stunned mood.

Explanation:

Analyze each option based on the mood - shift concept. The description of Mr. DePalma becoming a strict disciplinarian creates a tense atmosphere, which aligns with a shift to a tense mood. The other options do not match the description of the mood - shift as well. For example, being emotional and grief - stricken is more related to a sad mood, being a comforting figure is more about a warm mood, and being indifferent is not related to a "stunned" mood in a typical sense.

Answer:

He becomes a strict disciplinarian, showing a shift to a tense mood.
