Perhaps technically, but άνθρωπος normally refers to people in general, not men.
I could not hear the 'οι' in the spoken text (even when it was slowed down), so I wrote ολοι άνθρωποι... lost another heart ;-(
‘All the men’ should be OK, as the both men and άνθρωποι have the sense of human, people in general.
I wrote All the human beings, which was marked wrong. However I think it should have been accepted.
