If all of the statements above are true, then which one of the following

Answer choices

  1. Correct63% picked this

    Some immoral actions that are not performed in public are not accompanied by

    Why this is right

    This contradicts the second sentence. The part is this answer about "not performed in public" is meaningless; it's just there to confuse people. Typically, when a correct answer to Must Be False contradicts a conditional, it throws some other detail into the sentence to distract us from the fact that they're presenting the Trigger and then saying the opposite of the Outcome. The second sentence said "all immoral actions are accompanied by feelings of guilt". Yet this answer is talking about some immoral actions that are not accompanied by feelings of guilt.

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

  2. Out of Scope: wrong9% picked this

    Immoral actions are wrong solely by virtue of being accompanied by

    We never talked about whether anything is wrong or not, so there's no way to contradict a claim about why something is wrong.

  3. Compatible8% picked this

    Some actions that offend public sensibilities if they are performed in public are not accompanied

    This doesn't contradict anything. It would only contradict if it were talking about immoral actions. (This answer could be referring to my armpit noises, which definitely offend public sensibilities when I do them in public. It's not immoral for me to be doing them. It's just unseemly. But I have no feelings of guilt. The children love the noises, and that's all I care about.)

  4. Out of Scope: not immoral10% picked this

    Some actions that are accompanied by feelings of guilt are not immoral, even if they

    We only learned about immoral actions, so we can't contradict any claims about actions that are not immoral.

  5. Compatible10% picked this

    Every action performed in public that is accompanied by feelings of

    This is just trying to make a weird conditional chain out of all the ideas we were told. We wouldn't be able to derive this conditional chain from the stimulus (i.e. it's not a valid inference), but it doesn't contradict anything in the stimulus. In order for this to be the right answer, we would have needed to have been told that "there exists some action that is performed in public and accompanied by feelings of guilt, but is not immoral".
