Help with Am. Govt. homwork/study guide?

Question

I have a test in American Govt tomorrow. I was absent for the review today (had a doctors appt). But anyway, on our study guide it tells us this:

Are the following questions a DELEGATED POWER of the national government? If so, is it an ENUMERATED or IMPLIED power? Or, is it a CONCURRENT power held by both the states and national government or a power RESEVERED to the states?

1. Power to regulate commerce

2. Power to collect an excise or sales tax

3. Power to inspect foodstuff

4. Power to establish schools

5. Power to construct roads

10 pts to the best answer. I tried to answer these myself but am really lost. I wanted to stay there for the review today (where my class went over the answers) but yeah... I need help.

Thanks :)

Answer 1

All powers are delegated by the Legislature to the President through the departments created by laws.
