Summary
Most classic jazz recordings won’t be transferred onto compact disc. Why? Because the only preexisting recordings that record companies transfer onto compact disc are those they think will be profitable on compact disc, and few classic jazz recordings are played on the radio.
Missing Connection
Based on the argument’s premises, we only know that few classic jazz recordings are played on the radio and the only preexisting recordings that record companies transfer onto compact disc are those they think will be profitable on compact disc. So why does the author conclude that most classic jazz recordings won’t be transferred onto compact disc?
The author’s conclusion follows logically if we assume that if a preexisting recording isn’t played on the radio, record companies won’t believe it will sell well enough on compact disc to be profitable (Contrapositive: For record companies to believe a song will sell enough on compact disc to profitable, it must be played on the radio).

It doesn’t matter what percent of the recordings that record companies believe can be profitably transferred to compact disc are classic jazz. We need an answer that confirms that most classic jazz recordings won’t be transferred onto compact disc.
b
Few compact discs █████████ ███████ ████ ██████████ ███ ██████ ██ ███ ██████
It doesn’t matter how many existing compact discs featuring classic jazz are played on the radio. The correct answer must verify that, overall, most classic jazz recordings won’t be transferred onto compact disc.

This is the opposite of what we need. The correct answer must say that for record companies to believe a song can be profitably sold on a compact disc, it must be played on the radio. (C) flips the sufficient and necessary conditions.
d

The argument never discusses the preservation of jazz recordings. The correct answer choice must explain why most classic jazz recordings won’t be transferred to compact disc.

No recording that ██ ███ ██████ ██ ███ █████ ██ ███ ████ ██████ █████████ ███████ █████ ██ ██████████ ██ ███████████ ██ ███████ █████
Contrapositive: For record companies to believe a recording would be profitable if transferred to compact disc, the recording must be played on the radio. If (E) is true, we can infer the argument’s conclusion, that most classic jazz recordings will not be transferred onto compact disc.
