Which two islands were invaded by the Japanese after the attack on Pearl Harbor?

The correct answer is that Guam and Wake Island were invaded by the Japanese following the attack on Pearl Harbor. This invasion occurred as part of Japan's broader strategy to expand its territory across the Pacific in response to the United States' presence in the region.

Guam, an American possession since the Spanish-American War, was overrun shortly after the Pearl Harbor attack, occurring in December 1941. The Japanese aimed to eliminate American defensive positions in the Pacific, ensuring that their advance could continue unimpeded. Similarly, Wake Island, which was critical due to its strategic location, was also attacked and captured soon after Pearl Harbor.

Other options consist of locations that either were not subject to invasion at that specific time or did not have the military significance of Guam and Wake during the early stages of World War II. The selections of Tahiti and Fiji are incorrect because they were not involved in these initial military actions by Japan, while Hawaii is primarily known for the attack itself rather than being invaded afterward. Midway, though strategically important, was not invaded until later in the war. Hence, the focus on the invasions of Guam and Wake Island highlights the early tactical moves by Japan in the Pacific theater.
