At a concert, exactly eight compositions -- F, H, L, O, P, R, S, and T -- are to be performed exactly once each, consecutively and one composition at a time. The order of their performance must satisfy the following conditions:T is performed either immediately before F or immediately after R. At least two compositions are performed either after F and before R, or after R and before F. O is performed either first or fifth. The eighth composition performed is either L or H. P is performed at some time before S. At least one composition is performed either after O and before S, or after S and before O.Which one of the following lists the compositions in an order in which they could be performed during the concert, from first through eighth?
Answer(s): A
The only potential snag in this Acceptability question - and believe us, it's not much of a snag - is that we have many more rules here than we have wrong choices, so we can't be sure which of the rules are going to knock out the four losers. No matter; the approach is the same. As it turns out, all five choices have either L or H 8th (Rule 4), and all have P preceding S (Rule 5). But Rule 1 knocks out option [O, T, P, F, S, H, R, L]. by separating T from either R or F. Rule 2 knocks out option [T, F, P, R, O, L, S, H]. by placing R and F too close together. Option [P, T, F, S, L, R, O, H] unacceptably places F and R too close together (Rule 3), and [P, T, F, S, O, R, L, H] does likewise with O and S (Rule 6).

The fact that O is performed right after T ought to draw your eye right back to the Master Sketch, where both O and Tare explicitly mentioned in concrete rules. If O comes after T, then clearly O (Rule 3) will occupy slot 5 rather than slot 1;and if T precedes O, then clearly T (Rule 1) will have to follow immediately after R, for:______RTO______L or H12345678The question concerns F, which conjures up Rule 2. Under these circumstances, the only way to keep F the requisite distance from R is to assign F to slot 6 or 7.

Answer(s): C
We are asked to choose a possible 1-2-3 trio given that S is in slot 4:_________S_________L or H12345678The mention of S should conjure up O, and our Master Sketch helps us out. O can't be placed next to S (Rule6), so O will have to take slot 1 (Rule 3). Choices [F, H, P], [B. H, P, L], [E. P, R,T], all bite the dust: O is definitely first, here. Now that it's down to two choices, why mess around? Sketch in both options [O, P, R] and [O.P.T] and decide which one works. If we put option [O, P, R] into the first three slots, no problem: T and F will take slots 6 and 7, in that order, leaving slots 5 and 8 for L and H. But [O.P.T] won't fly. Making the first three "O, P, T" leaves R and F unacceptably close together towards the far end of the sequence.
