Question

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 solve this, we analyze each option in the context of supporting a Part A answer (likely about the breakdown of US - Japan relations).

• Option A: "The attack on Pearl Harbor" is an event that happened later and is a result of the deteriorating relations, not a detail that shows the start or progression of the breakdown.
• Option B: "a decade of deteriorating relations" gives a broad overview of the time - frame of the worsening relationship, which is a key detail to support an answer about the breakdown of relations between the US and Japan.
• Option C: "This breakdown began in 1931" only gives the start year but doesn't show the overall context of the deteriorating relations over time as well as Option B.
• Option D: "In the summer of 1937 launched a full - scale attack" is about a specific attack (likely the Sino - Japanese war - related) and not directly about US - Japan relations' breakdown.

To determine the best supporting detail, we analyze each option. Option A describes an outcome of deteriorating relations. Option C only gives a start year. Option D is about a different conflict. Option B ("a decade of deteriorating relations") provides a broad context of the worsening US - Japan relationship, making it the best support.

Answer:

B. "a decade of deteriorating relations"
