Answer choices

  1. No Connection15% picked this

    Everyone who is excessively generous is

    This is the style of trap answer we knew was coming, acting as though the concepts of generosity and boldness can be connected to each other conditionally. This answer is saying: Excessively generous ? Not bold We were told: Excessively generous ? Not levelheaded Can we get from "not levelheaded" to "not bold"? No, we were given this Levelheaded ? Not bold Bold ? Not levelheaded The only thing we know about excessively generous people is that they're not levelheaded. We don't know anything about what proportion of people who are "not levelheaded" are bold or not bold.

  2. Unknown Trigger3% picked this

    Everyone who is not bold is

    This is another trap trying to conditionally connect the concepts of generosity and boldness, which were not connectable. This answer is saying: Not bold ? Excessively generous We were told: Levelheaded ? Not bold Bold ? Not levelheaded "Not Bold" never shows up as a trigger, so we know this answer is not something we can derive.

  3. Unknown Trigger7% picked this

    No one who is not bold lacks

    This is another trap trying to conditionally connect the concepts of generosity and boldness, which were not connectable. The form "no one who is A is B" becomes "everyone who is A is not B" But here there will be a double negative that could mess us up. "No one who is A lacks B" becomes "everyone who is A is not lacking B", which means "everyone who is A possesses B". If I say "No one who is rich lacks a luxury car" I'm saying "everyone who is rich possesses a luxury car". So saying, "No one who is not-bold lacks generosity" is saying, "everyone who is not-bold possesses generosity". So this answer is saying the same conditional that (B) was saying, which of course would guarantee they're both wrong (because they can't both be right) Not bold ? Excessively generous

  4. Correct69% picked this

    If someone is levelheaded, then that person is neither bold nor

    Why this is right

    We had these conditionals: Excessively generous ? Not levelheaded Levelheaded ? Not excessively generous Levelheaded ? Not bold Bold ? Not levelheaded As we can see from the 2nd and 3rd line, if someone is levelheaded than they are not excessively generous and not bold. When we say, "If A, then neither B nor C" it looks like, "A ? ~B and ~C" So this answer is saying Levelheaded ? ~Bold and ~Excessively Generous

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

  5. Unknown Trigger6% picked this

    If someone is not levelheaded, then that person is either bold

    These were the conditionals we were given. Excessively generous ? Not levelheaded Levelheaded ? Not excessively generous Levelheaded ? Not bold Bold ? Not levelheaded This answer choice starts with the trigger "If not levelheaded". We don't have that trigger, so this answer is doomed.
