West's "jump shift" (bidding a new suit and skipping one level) shows an unbalanced hand with at least 5 hearts and 5 diamonds, and interest in Game. In such case East should show preference for one of West's two long suits. East must bid the suit in which he holds the most cards, or, when he has an equal number of cards in both suits, bid the first suit West bid. So what should East bid ?
