The best way to study for a music concepts test is to study the music you have a test on (i.e. research all information and look it through).
Hope this helped and good luck on your test!!!! :DDD

Yes there are such sentences. “He eats food.” and “People often sleep.” are both examples.
This isn't neccessarily true. Your introduction can still make sense without the hook, and the information inside the introduction part should really not directly depend on the hook to explain them, they should either be self explanatory, or you should explain them there.
Hopefully this helps!
