<h3>
Answer: Choice J (lower right corner)</h3>
-20 and -7 are in circle A, but outside circle B
0, 9, 81 are in circle B
=====================================================
Explanation:
The set of whole numbers is
{0, 1, 2, 3, 4, ...}
While the set of integers is
{ ..., -3, -2, -1, 0, 1, 2, 3, ... }
The difference is that integers involves negative numbers.
-----------------
The upper left corner is incorrect because the "0" should be in set B since 0 is also a whole number. The lower left corner is also ruled out because of this reason.
The upper right corner (choice H) is incorrect as well because 10 and 46 are whole numbers also, so they belong in set B which is a better description/place for them.
So basically the numbers 0,1,2,3,... go in circle B. The negatives of those values will go in circle A, but outside circle B. Only choice J describes this kind of situation.
