At the very least, joe average and bill gates are both identically limited by:
a. their wealth.
b. the 24 hours that comprise a day.
c. their knowledge.
d. their influence.

The correct answer is option 'B': The 24 hours that comprise a day

Explanation:

For comparison between 2 random variables only those values can be said to be identical that have the same values.

From the given options if we compare Joe and Bill Gates we conclude

1) The 2 person's are not identically limited by wealth as the wealth difference can be large.

2) Similarly they can have a vast difference in their knowledge.

3) Person that has larger wealth and knowledge will naturally have larger influence.

Now since the length of a day is 24 hours and this is a universal truth no matter what the circumstances we conclude that they both are limited by this parameter no matter whatever be the difference between the 2.
