Question

the doolittle raid in the spring of 1942 proved that japans homeland was
○ powerful.
○ defenseless.
○ protected
○ conquerable.

Explanation:

The Doolittle Raid was a U.S. air strike on Japanese mainland targets in 1942. While it caused limited physical damage, it demonstrated that Japan's home islands were not immune to attack, meaning they could be targeted and overcome. "Defenseless" is incorrect as Japan had defenses, just not enough to stop this small raid; "powerful" and "protected" contradict the raid's implication.

Answer:

D. conquerable
