(I hope this is in the right section, I apologize if it isn't)

I would like to jump straight to the point, I am a first year college student and I have my Math preliminary exam in about... Four or so hours and there's been something that I don't quite understand how to answer from notes I have, (I was absent that day regarding this question in particular and was stupid enough not to ask the professor about it sooner)

Here is the question, copy pasted:

_____________

3. In each of the following, determine which one of the sets N, J, Q H, R and Ø is equal to the given set.

a) J U Q

b) J (intersection) Q

c) N (intersection) H

d) H U R

______________

Does anyone know how to answer this question? We had previous ones that I knew how to answer (which I will post below) and I understand what this question asks, I just don't know how to answer it. For example, in the first question I know it says: The integer set Union the Rational set = (and then you add one of the above listed sets I guess?) I'm not quite sure what they mean. Any help would be greatly appreciated <3

Here are some of the previous questions (That I knew how to answer):

1. Insert or in the blank to make the statement correct.

a) 15____ N e) 0____ Q

b) 1.41421____H f) 2009____ J

c) -3____ J g) ____ R

d) ____ Q h) -5____ H.

2. Insert or in the blank to make the statement correct.

a) N ____ Q

b) R ____ Q

c) J ____ N

d) J ____ R

e) R ¬____ N

f) J ____ Q

g) H ____ R

h) {0} ____ J
