Stimulus

If there is an election, you can either vote or not. If you vote, you have the satisfaction of knowing you influenced the results of the election; if you do not vote, you have no right to complain about the results. So, following an election, either you its results or you will have no right to complain.

What this question is testing

Parallel

Conclusion

The author is laying out a clean either/or: either you voted (and got satisfaction) or you didn't (and forfeited your right to complain). One way or the other, you end up with one of those two outcomes.

Evidence

The reasoning is built on a forced two-way split. There are only two options — vote or don't vote — and each option has its own consequence. Voting gives satisfaction. Not voting takes away the right to complain. Since one of the two must happen, one of the two consequences must follow.

Evaluate

For Parallel Reasoning questions, abstract the structure away from the topic. Here is the skeleton:

The right answer needs to match this skeleton exactly: a forced binary choice (X or not-X), two conditionals — one for each branch — and a conclusion combining the two outcomes with "or."

Watch out for answers that introduce extra conditions, missing branches, or comparisons (better off, more likely, etc.) that the original argument does not have.

Goal

Find the answer with a clean A-or-not-A split, two distinct outcomes (one per branch), and a conclusion that says "either outcome 1 or outcome 2."

  1. Bad Conclusion Match4% picked this

    When you rent a car, you can either take out insurance or not. If you take out insurance you are covered, but if you

    This argument has the right opening structure (insured or not, with each branch leading to an outcome), but the conclusion is different in kind. The original concludes a disjunction ("X or Y"). This conclusion is a comparative judgment ("you will be better off if insured"). That is a different logical move — picking a winner between two options — not the original's "you will end up with one outcome or the other."

  2. Bad Premise Match8% picked this

    If you go for a walk, when you are finished either you will feel relaxed or you will not. If you feel relaxed, then

    The conditionals here are tangled. The original says "If you vote, then satisfaction" and "If you don't vote, then no right to complain" — clean one-step conditionals. This answer says relaxed muscles will likely not be sore, but if they do feel sore, they will become better conditioned faster. That is a probabilistic chain, not a clean if-then. And the conclusion ("sore or better conditioned") doesn't cleanly combine the two outcomes the way the original does.

  3. Bad Premise Match12% picked this

    If you attend school, you will find the courses stimulating or you will not. If your teachers are motivated, you will find the courses

    The conditionals run the wrong way. The original goes from your action (vote or not) to the outcome (satisfaction or no complaint). This argument goes from a condition (teachers motivated or not) to the result you experience (stimulating or not), and then concludes about the teachers' motivation. That's a contrapositive-and-conclude move, not the parallel "X or not-X; therefore outcome 1 or outcome 2" structure of the original.

  4. Correct72% picked this

    If you use a computer, its messages are either easily readable or not. If the messages are easily readable, they are merely password protected.

    Why this is right

    This is a clean structural match. Step by step: the original says "election forces a choice — vote or don't" / "vote → satisfaction" / "don't vote → no complaint" / "so satisfaction or no complaint." This answer says "computer message forces a choice — easily readable or not" / "readable → password protected" / "not readable → encrypted" / "so password protected or encrypted." Same skeleton: A-or-not-A, two conditionals (one per branch), and a conclusion combining the two outcomes with "or."

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

  5. Bad Conclusion Match3% picked this

    When manufacturers use a natural resource, they are either efficient or inefficient. If they are inefficient, the resource will be depleted quickly. If they

    The first three sentences set up a clean dichotomy (efficient or inefficient, with consequences on each side). But the conclusion goes off the rails: "either manufacturers are efficient or they should be fined." "Should be fined" is not one of the consequences set up by the conditionals (depleted quickly vs. last much longer). The conclusion introduces a brand-new term, breaking the parallel structure.
