Thanks for the help! :)

Zowie · Answer

The first one I believe is D.
The second one is definitely C.

Could you explain your reasoning for question #1

Zowie · Answer

Honestly it's what I think. Not a 100% correct answer. But the second one is definitely C. I know that for a fact.

CSWSlearning · Answer

Ok...

CSWSlearning · Answer

The answer for number 1 was C and the second one was B  :)  thanks for trying though

dude · Answer

Question 1 could've been C because you can only accommodate 500 people and you cant have a fraction of a person, therefore so not ALL real numbers would fit
