I agree with this statement completely. But the question posted is on a test,
not in a class. Unless this issue was raised in class, and that's not at all
clear, the content will put some students off. That's not fair, on a test of
mathematics.
Perhaps the reader used classes to include testing. Even in that case,
I still say, raise it in class, but not on a test, unless, possibly,
the social issue was also raised in the class.
