## Step 1<br />The question is asking for the reason why Japan attacked the U.S. naval base at Pearl Harbor. The options provided are:<br />- U.S. trade sanctions had caused shortages of oil, gas, and rubber.<br />- Japanese Americans had been relocated to internment camps.<br />- The Japanese naval fleet had been defeated at the Battle of Midway.<br />- The U.S. strategy of island hopping had disturbed Pacific trade routes.<br /><br />## Step 2<br />The correct answer is "U.S. trade sanctions had caused shortages of oil, gas, and rubber." This is because, prior to the attack on Pearl Harbor, the U.S. had imposed trade sanctions on Japan, which severely restricted Japan's access to essential resources such as oil, gas, and rubber. These resources were vital for Japan's military and industrial operations.<br /><br />## Step 3<br />The other options are incorrect for the following reasons:<br />- Japanese Americans had been relocated to internment camps: This event occurred after the attack on Pearl Harbor, not before it.<br />- The Japanese naval fleet had been defeated at the Battle of Midway: This event also occurred after the attack on Pearl Harbor.<br />- The U.S. strategy of island hopping had disturbed Pacific trade routes: This strategy was developed and implemented after the attack on Pearl Harbor.
