Incorrect. The paradox surrounds strengthening of major muscles of the leg, not small muscles of the feet and ankles. This answer requires assuming strengthening those muscles results in strengthening leg muscles, but there's no information supporting that.

Incorrect. If anything, this makes the paradox worse by suggesting that any benefits should be short-lived.

Correct. Argument or Facts:
Facts

Question Type:
Paradox

Stimulus Summary:
Toning shoes don't give leg muscles more exercise than regular shoes, but people who switch to them experience leg muscle strengthening.

Answer Anticipation:
If the shoes themselves aren't strengthening muscles, then there must be some other change that accompanies them that results in it. Maybe people who buy them are doing so as part of a broader attempt to build strength. Anything to that effect will resolve the paradox, so we should stay flexible while analyzing the answers.

Answer Explanation:
This answer is similar to the anticipation—people who wear these shoes walk more (i.e., exercising), which would explain the strengthening leg muscles. It's not the shoes—it's the additional exercise.

Key Takeaway:
For Paradox questions, if a change is brought up (here, leg muscle strengthening), think about what could lead to that change, as it should guide you to the answer. But be sure that the change is connected to the paradox!

Incorrect. Not injuring people doesn't explain how it makes them stronger. It might rule out something that would prevent them from getting stronger, but it doesn't explain the strength gain itself.

Incorrect. Marketability doesn't explain how shoes that don't strengthen leg muscles would still result in the leg muscles being strengthened. This answer is out of scope.
