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

The correct answer choice is (B)

If only one experiment is performed and no red flasks remain, then the original red flask (flask 1) must have been used in the experiment. Flask 1 cannot be mixed with flask 2 because that would produce a red chemical, so the experiment must be either 1 + 3 (leaving 2 and 4 unused, producing a B, B, O result), or 1 + 4 (leaving 2 and 3 unused, a G, B, G result). Answer choice (B) is correct because it presents B, G, G (2, 1 + 4, 3). This is possibility #5 in the master list.
