A jazz band will play two one-hour sets at a jazz festival. In the ban

Official Explanation

First examine the tunes they have already scheduled. Set 1 already has two ballads, so its remaining two songs must be up-tempo, in order that the set have more up-tempo songs than ballads. Also, only one of the remaining two songs in Set 1 can be an original because the festival producers have requested more standards than originals per set.

Next, Set 2 has only one ballad, so the remaining song can be up-tempo or ballad. However, it has to be an original because the band wants to maximize the number of originals it is allowed to perform in each set. One consequence of these observations is that a standard ballad cannot be performed in either set (in Set 1 because it’s a ballad, and in Set 2because it’s a standard). Thus, you can eliminate choices (A) and (B), which list the standard ballad “It Never Entered My Mind.” So, the songs that can be performed in either set can only be original (because of the need for an original in Set 2) and up-tempo (because the need for up-tempo in Set 1). Choice (E) lists two such tunes, and it is thus the correct answer.

The right choice for Column 2 will be the one that lists two up-tempo standards: these can be performed only in Set 1. Note that these cannot be performed together in Set 1—rather, they have to be paired with an up-tempo original—but that’s not what the question is asking. Choice (C) lists two songs that can be performed only in Set 1.

Note that choice (F) lists one up-tempo standard, which can be performed only in Set 1, and one up-tempo original, which can be performed only in Set 2.
