I'm confused by the definitions I've read. In general, what is the difference between the Talmud and the Midrash? Thank you for your time and effort on my behalf.

can you draw lines on shabbat?

What did Yaakov Avinu learn in Yeshivas Shem V'ever? He spent 22 years learning in yeshiva long before klal yisrael received the torah?!

am i allowed to sit in a non-kosher restaurant with a Kipppah? Can i eat a double-wrapped kosher meal? What if the meal has no kosher symbol on it, but I reserved Kosher and the waiters say they got it delivered as special kosher, and everyone else is being served on normal plates etc. while i get a tin with a plastic cover? (this happened last night at a dinner). can i assume its kosher?

I need informationb on halacha and birth control. thank you
