How could these questions be viewed as racist or racially insensitive?

These questions could be racially insensitive because the only people they discuss are Caucasian men. This could be disrespectful or racially insensitive to African Americans, Native Americans, Chinese Americans, and Japanese Americans. They all played huge roles in the negative aspects of American history, and yet they are completely ignored in this test. They could have mentioned internment camps, the trail of tears, or, when they were discussing the emancipation proclamation at the end, they could have discussed the issue of slavery that President Lincoln finally addressed.
