It is well known that teenage boys tend to do better (1 )math than girls, that male high school students are more likely than their female counterparts ( 2 )advanced math courses like calculus, that virtually all the great mathematicians ( 3 ) men.

The conclusion: males have (10 )superior mathematical reasoning ability.
