The question is which basic principle of individual choice do the statements best illustrate? and let's look to all answer options to find the best answer.
00:16
A, the cost of something is what you give up to get it.
00:21
This one looks very good.
00:24
It's the correct answer.
00:25

00:29
So she cannot do everything.
00:34
So she need to choose and the cost of something is what you give up to get it.
00:41
Let's look to all other answers just to be sure that all of them are incorrect.
00:47
B, people usually exploit opportunities to make themselves better off.
00:53
Well, yeah, it's a good statement, but it's nothing about this situation.
