Does this make sense? I have no idea what any of this means.

Qu’est-ce que les marchands vendent dans cette rue?

Any french speakers? i need some . how would i say 'my oldest brother is very tall, interesting, and good at drawinng.' in french? would it be: mon (i don't know the french word for oldest) frère est très grand, intéressant, et bon à dessin. also, how would i say 'my dad is good at his work' in french?

Can someone translate this to french? “my mother swims from time to time. my brother always sings. my grandma rarely dances.”
