No they're not!
how do I know that is "answers" and not "answer"? Very confusing for me. Someone can help, please?
I think - but am not sure - because the verb is plural. Which would indicate that there's no difference between answer and answers.
Yes, we only know because it is हैं and not है. Masculine nouns that do not end in aa do not change in the plural form.
Because there is tumhare before. If it was singular it would have been tumhara...
