Question
HI. I recently made a car rental reservation for an upcoming trip. I only have to pay when I pick up the car and can cancel the reservation before that. I then found a lower price with another company. Can I make a reservation with the 2nd company but still keep the first one, just in case there is an issue with the 2nd company when I get there?

Question
Dear Rabbi, Is there a problem with a kohen flying on a plane transporting a dead body? Truth is, passengers usually don’t know the plane has one. The one time I found out was when a plane I was on landed and they announced they were stopping to ceremoniously drop off the body of a soldier killed while on duty. That soldier was not likely Jewish. But all airlines, El Al included, do transport corpses, usually without letting passengers know.

Question
Shalom! I would like to know some halachot about grafting: Is it allowed to graft trees from the same plant species (e.g. two apple trees)? Is it allowed to plant such a tree? Is it allowed to plant a grafted tree which contains two species (e.g. a quince and a pear)? Is it allowed to plant a tree that is in itself a mixture of two species (e.g. a plumcot, which is a hybrid from a plum x apricot)? Thank you!
