What do the terms race and ethnicity mean to you ? African Americans

Why are these concepts important to the United States?

The teacher apparently is asking for your opinions. However, having information will help you to develop your own opinions.

Since this is not my area of expertise, I searched Google under the key words "United States Race Ethnicity" to get these possible sources:

I hope this helps. If not, you can expand the search usingthe same or other key words. Thanks for asking.

Can someone tell me if this is correct or not queastion His grandmother really enjoys spending the afternoon at the center for senior citizens.
my answer
His grandmother enjoy spending the afternoon at the center for senior citizens.

Your answer is almost correct but there is a small mistake. The correct sentence should be: "His grandmother enjoys spending the afternoon at the center for senior citizens."

In this sentence, the subject is "his grandmother" and the verb is "enjoys." The word "enjoys" is used instead of "enjoy" because in the sentence, the subject is singular (grandmother), so the verb should also be singular (enjoys). Additionally, the word "the" should be included before "afternoon" to indicate a specific afternoon at the center.

Overall, your understanding is correct, but the small mistake can be corrected to make the sentence grammatically accurate.
