Question

What is a step you should take when asking someone to write a letter of recommendation for you?

Make sure that person only has one copy of the letter
Make sure the person hands you the letter in an unsealed envelope
You should sign the back of the envelope
You should thank the person who wrote the letter

This is for SAT Prep (Basic Skills SAT)

Answer 1

You should thank the person who wrote the letter.

Answer 2

You should definitely thank the person who wrote the letter!

This person is essentially helping you raise your chances, with the recommendation letter, to get into a decent college/university.
(The other three choices you were given don't really make sense.)

Hope this helps a lot! :)
