In Q4, I fail to understand why the negation cannot be that Some small animals cannot move more rapidly than large animals. This captures the full range required for the negation. Can someone help me understand why that is not a valid negation?

For question 7, I eliminated option 1 by focusing on the word simultaneous. It is emphasizing the simultaneous status of a celestial body, but the stimulus emphasizes Pluto changing its orbit through time. We are not viewing the problem through the lense of simultaneousness.

Just wanted to share the way I looked at it. 🤘🏻

Up to now I though that question stems would consist of verbatim quotes from the stimulus and this through me off! Not a mistake I will be making any longer.
