Opposites attract

Quiz time again. This week I have been pondering a nice set of easy questions for you to answer. We all see pairs of letters everywhere, mostly opposites. Below you'll see 2 letters. Each is the first letter to a word, and each pair of letters are pairs of words, that must be opposites to each other. See how many you can get. (The first one is done for you)
