Check it. Assuming that the passive players will call anyway (and given the size of the pot, it wouldn't be incorrect for them to call with gutshots), a bet doesn't accomplish very much. Checkraise MP1's bet to knock out UTG if possible.

However, if one of the passive players bets, I would just call. Let me elaborate before I get flamed: If one of the super passive players who is unlikely to semi bluff bets, it probably means a straight. Given that I'm most likely behind, but will be far ahead if the board pairs, my equity isn't particularly sensitive to the number of players in the pot. I'll win if I fill up, and lose if I don't. Thus, I wouldn't mind callers behind me because they'll pay me off if I do infact fill up.
