His point appears to be that "numbers" automatically means integers. After all, he is taking the GRE so he has only had 12 years of school and 4 years of college. You can't expect him to have worked with fractions or irrational numbers in that little time!

Frankly, I'm surprised he didn't complain that they didn't specifically tell him that the test is in English! Otherwise how can he be sure what "of" and "the" mean?
