Complete Question Explanation
(The complete setup for this game can be found here: lsat/viewtopic.php?t=2408)

The correct answer choice is (E)

If only one experiment is performed and no orange flasks remain, then the original orange flask (flask 4) must have been mixed with one of the other flasks (this occurs under possibilities #4, #5, and #6 in the setup). Thus, because flask 4 must have been used in an experiment, answer choice (E) is correct.
