Answer:
Number line with open circle on 2 and shading to the right.
Explanation:
The key words in the question were more than 5. So the debate club needs more than 2 more members. Closed circles mean that a value can also be equal to the number they're on. A closed circle on 2 would be incorrect because it says that the number of members the debate club needs can include two, but the value must be more than two.
So now it's narrowed down to the last two options. But since we know that they need more than 5 members, and not less, the shading will be on the right. So it's the last option.
