Stimulus

Critic: Most chorale preludes were written for the organ, and most great chorale preludes written for the organ were written by J. S. Bach. One of Bach’s chorale preludes dramatizes one hymn’s perspective on the year’s end. This prelude is agonizing and fixed on the passing of the old year, with its their own feelings. Some artists do. Master artists never do, and Bach was a master artist.

Answer choices

  1. Out of Scope: Bach's beliefs10% picked this

    Bach believed that the close of the year was not a time for optimism

    We have precisely zero information about anything Bach believed, so we have no ammunition for contradicting any statement about Bach's beliefs.

  2. Must Be True8% picked this

    In composing music about a particular subject, Bach did not write the music in order to express his

    This is one of the inferences we derived, so this would be correct if the question wanted to know what must be true.

  3. Correct68% picked this

    In compositions other than chorale preludes, Bach wrote music in order to express his feelings

    Why this is right

    This contradicts the inference we made about Bach based on the final two claims. Master artists never create to express their own feelings. Bach was a master artist. Therefore, Bach never created to express his own feelings.

    Skill tested: Must be False · how this choice captures the argument's function is the move to repeat next time.

    We could only contradict this answer if we knew that "Most of Bach's CP's were written for the organ". Do we know this? No, we don't. We can always tell that a most fact is not derivable if we never received a most fact about that group. We received most facts about these groups: chorale preludes great chorale preludes written for the organ This answer is talking about an unknown group, Bach's chorale preludes If the passage didn't say "Most Bach's chorale preludes" then we can't derive anything about "Most Bach's chorale preludes".

We can always tell that a most fact is not derivable if we never received a most fact about that group. We received most facts about these groups: chorale preludes great chorale preludes written for the organ This answer is talking about an unknown group, great chorale preludes It's entirely possible that most great chorale preludes were written for non-organ instruments. We know that most chorale preludes in general were for organ. But it could be that most of the chorale preludes for organ are lame and most of the great chorale preludes were written for piano.
