Correct. Argument or Facts:
Facts

Question Type:
Paradox

Stimulus Summary:
Differences in air temperature make wind. From this, you might expect that Earth, which is heated by the sun, has more wind than Jupiter, which is not. However, Jupiter is many times windier than Earth.

Answer Anticipation:
Since it is established that temperature differences cause wind, the correct answer will probably mention a source that provides heat on Jupiter that is much bigger than the amount of heat provided by the Sun on Earth.

Answer Explanation:
While this answer doesn't discuss the scale of the heat, it does establish a constant source of heat on Jupiter. We'd defer on this and then select it after eliminating all other answers.

Key Takeaway:
When a question establishes a general principle (here, temperature causing wind) and then talks about one specific example of it (here, the Sun), look for answers that deal with other potential situations where the principle would apply.

Incorrect. Since this answer doesn't connect these gases to temperature or wind, it doesn't help to explain the situation.

Incorrect. This is a common style of trap answer in Paradox questions. While this answer aligns with the paradox, it doesn't explain it. Why are gaseous planets sometimes windier than rocky planets? This answer doesn't suggest an explanation, instead simply stating that they are.

Incorrect. Even if Earth is less windy than average, that doesn't present a reason as to why, and why Jupiter is windier.

Incorrect. First, this answer doesn't explain what drives those winds. Second, it doesn't compare these winds to Earth. Finally, and most importantly, it doesn't explain why Jupiter is so windy.
