Hi there! Would you kindly elaborate on question 7 about Pluto not being a planet? I suppose I am unclear on how an answer choice containing a necessary condition meets the criteria for a sufficient assumption question. It would not be sufficient for a celestial body to form an orbit around the sun because then asteroid would be a true planet, so it makes sense that choice E uses language indicating necessity. I'm not sure how this answer choice guarantees the conclusion. The curriculum has discussed how conditions can be both necessary and sufficient, but I do not think this is the case here. Thank you for your help! I might have missed a video that discusses this as well if you happen to know of one :-) All the best!
