Aaaah so you mean "elles" and "ils"?
You can look here, I don't know if it's accurate though. http://italian.about.com/library/fare/blfare116a.htm
Firstly, you were marked one for typing "reads" instead of "read". "reads" is only for "he/she/it".
Secondly, the sentence; "Which men read the newspaper?" - could be both past tense and present tense - depending on how you pronounce the word 'read'.
Seeing as you are learning present tense, you should assume it is the present tense required.
The past particle of the word 'read' is spelt the same as the present tense in English; they are just pronounced differently.
So, in written form - only the context can inform you if it is past or present tense. But, in speech - the pronunciation will inform you.
Hope that helps.
