Yeah I just did this prep-test a couple of days ago.

So we are looking for an AC that must be false.

The stimulus tells us that of all choral preludes, most of them were written for the organ. And, of those organ preludes, most of the great ones were by Bach. Then we have a bunch of details about the preludes but the last two sentence reveal more conditionals: some artists create to express their feelings, master artists never do, and Bach was a master artist.
(CP = chorale prelude, O = organ, GOCP = great organ chorale prelude, B = Bach, A = artist, EF = express your own feelings, MA = master artist).

CP --m--> O
GOCP --m--> B
(We can't deduce anything from these two statements)

A <--s--> EF
MA ------> ~EF
B ------> MA


Based on the above we can conclude that Bach never wrote music that expresses his own feeling so it must be false that a piece of music written by Bach was written to express his own feelings and hence answer choice C is correct.

Notice that the stuff about the organ doesn't affect the last conditional statements because they are about compositions in general and hence we can conclude that ALL of his compositions were written for reasons other than expressing his own feelings.

More often than not, when I see a must be false question, the correct answer seems to be having a certain sufficient condition occur without having the necessary condition occur - and such was the case here i.e. we know that if you are Bach, you don't write music to express you own feelings and the correct AC stated that Bach did write music to express his own feelings which can't be true.

all the other ACs could be true but don't have to be except for AC B) which must be true given the last three sentences of the stimulus.
