passage
from a distance, saturn appears to be a perfect sphere with its famous rings in motion around it. but saturn is not a sphere at all. the planet spins so quickly on its axis that the edges of saturn are pulled out at its equator, with the result that saturn flattens out somewhat in orbit around the sun. the amount of flattening is slight enough that the casual observer does not notice that there is anything unusual about saturns shape, but close - up images of saturn clearly reveal that it is not a sphere like the other planets in our solar system.
question
the passage implies that planets other than saturn

• do not spin quickly enough to flatten out
• do not have equators
• cannot be seen by casual observers
• are not spheres

Explanation:

1. Analyze the first option: The passage says Saturn spins quickly, causing it to flatten. It also says Saturn is not a sphere like other planets. So other planets don't flatten, implying they don't spin quickly enough to flatten.
2. Analyze the second option: The passage mentions Saturn has an equator due to its spin, but there's no info to say other planets don't have equators. Eliminate this.
3. Analyze the third option: The passage talks about casual observers not noticing Saturn's shape issue, not about seeing other planets. Eliminate this.
4. Analyze the fourth option: The passage says Saturn is not a sphere like other planets, so other planets are spheres. This option is wrong.

Answer:

A. do not spin quickly enough to flatten out
