Critic: Most chorale preludes were written for the organ, and most great chorale preludes written for the organ were written by J. S. Bach.

Statements

- Most CP's were written for organ. - Most great CP's for organ were written by Bach. - One of Bach's CP's sets to music a hymn about reflecting on the year that passed, disappointments and all. - That CP doesn't necessarily reveal Bach's attitudes, but it captures the text of the hymn. - Some artists create in order to express their own feelings. - Master artists never create in order to express their own feelings. - Bach was a master artist.

Evaluate

On Must Be False, the correct answer almost always does one of two things:

1. contradicts a conditional that was provided 2. contradicts some inference we can derive by combining claims

Were there any conditionals?

Yes, just one, "Master artists never do":

master artist → does not create in order to express their own feelings

Were there any inferences we could make by combining claims?

The last two claims allow us to say that . This, in turn, would allow us to say that the unnamed prelude the passage talked about was not written to reflect Bach's own feelings about the change of the year.

Goal

Let's look for something that contradicts the conditional, X is a master artist and does create to express their feelings

or look for something contradicting the inferences we made: Bach did sometimes create to express his feelings. Bach's prelude was expressing his own feelings.

Or anything else that we can contradict.

If the critic's statements are true, then on the basis of them which one of the following CANNOT be true?

  1. Bach believed that the close

    Out of Scope: Bach's beliefs

    Must Be True

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

  3. Correct

    In compositions other than chorale

    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.

  4. Most of Bach’s chorale preludes

    Unknown Most Group

    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".

  5. Most of the great chorale

    Unknown Most Group

    We could only contradict this answer if we knew that "Most great chorale preludes 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, 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.
