Question

as you read, identify the causes and effects of the attack on pearl harbor.
the attack on pearl harbor was the culmination of a decade of deteriorating relations between japan and the united states over the status of china and the security of southeast asia. this breakdown began in 1931 when japanese army extremists, in defiance of government policy, invaded and overran the northern - most chinese province of manchuria. japan ignored american protests, and in the summer of 1937 launched a full - scale attack on the rest of china. although alarmed by this action, neither the united states nor any other nation with interests in the far east was willing to use military force to halt japanese expansion

1. part b: which detail from paragraph 1 best supports the answer to part a?

a. \the attack on pearl harbor\
b. \a decade of deteriorating relations\
c. \this breakdown began in 1931\
d. \in the summer of 1937 launched a full - scale attack\

Explanation:

To determine which detail from paragraph 1 best supports the answer to Part A, we need to analyze each option. Option A just names the event (the attack on Pearl Harbor) without providing context related to the cause - effect relationship over time. Option B mentions "a decade of deteriorating relations" which is a general time - frame but not as specific as Option C in starting the timeline. Option D is about a later event (1937 attack on China) and not the start of the breakdown. Option C, "This breakdown began in 1931" clearly marks the start of the deteriorating relations (the cause) which is crucial for understanding the long - term build - up to Pearl Harbor.

Answer:

C. "This breakdown began in 1931"
