Simple Question Explanation Please

The OG question provides a picture of a number line with five labeled points; the answer choices are not as you've written them. In early printings of OG-11, there was an error in the diagram, and you must have that printing. In the correct diagram, the rightmost point is less than 2, which is why -2 is the right answer. There were a few other errors in that early printing of OG-11, and if you do a google search, you should be able to find the pdf document GMAC released which has a list of corrections.
