Stimulus

Any writer whose purpose is personal expression sometimes uses words ambiguously. Every poet’s purpose is personal expression. Thus no poetry reader’s enjoyment depends on of what the poet means.

  1. Unrelated to Goal14% picked this

    Writers who sometimes use words ambiguously have no readers who try to attain a precise understanding of

    Since the premises didn't define what a poetry reader's enjoyment does / doesn't depend on, the correct answer must define that idea or else we can never derive a conclusion that uses those words. So as soon as we look at this answer and see it doesn't define what a poetry reader's enjoyment does / doesn't depend on, we can eliminate it.

  2. Unrelated to Goal4% picked this

    Writers whose purpose is personal expression are unconcerned with whether anyone enjoys

    Since the premises didn't define what a poetry reader's enjoyment does / doesn't depend on, the correct answer must define that idea or else we can never derive a conclusion that uses those words. So as soon as we look at this answer and see it doesn't define what a poetry reader's enjoyment does / doesn't depend on, we can eliminate it.

  3. Correct66% picked this

    No writer who ever uses words ambiguously has any reader whose enjoyment depends on attaining a precise understanding

    Why this is right

    This has the New Term from the conclusion we're insisting on, so let's give it a look. It's a conditional in the form of No A's are B, which translates into A → ~B if you're a writer that then you have no reader ever uses words → whose enjoyment depends ambiguously on attaining a precise understanding If you're a poet, your purpose is personal expression, so you sometimes use words ambiguously. So every poet is a writer who sometimes uses words ambiguously. According to the rule in this answer choice, "every poet has ZERO readers whose enjoyment depends on attaining a precise understanding of what the poet means". Since poets' readers are poetry readers, this is saying that ZERO poetry readers' enjoyment depends on attaining a precise understanding of what the writer means. Thus, we've derived the conclusion!

  4. Too Weak11% picked this

    Without digging in too deeply, we would know this is wrong because of the word "Most". That quantifier leaves room for exceptions, but we're doing Sufficient Assumption and we must 100% prove our conclusion, airtight, no exceptions. If we dug in more deeply, it's a mess. It's only saying that if you looked at all the writers whose readers' enjoyment doesn't depend on attaining a precise understanding of the writers' meaning, then most of those writers would be poets. But that doesn't even mean that most of a poet's readers are people whose enjoyment does not depend on a precise understanding. And even if it did mean "most of a poet's readers are the type of readers we're talking about in the conclusion", we would still call this too weak, since we need to prove that ALL of a poet's readers are of this type. If I say, "Most people who have played in a Superbowl weigh over 240 lbs", that doesn't mean that "most people who weigh over 240 lbs have played in a Superbowl".

  5. Opposite of our Goal5% picked this

    Readers who have a precise understanding of what a writer has written derive their enjoyment

    We're trying to prove that a whole class of readers does not have their enjoyment depend on attaining a precise understanding. This is talking about people whose enjoyment does depend in part on attaining a precise understanding.
