@Williamh Visualize them as subsets and supersets. For it to be a special class, it must be immutable i.e., the special class has to be immutable, but just because it is immutable, does not mean it has to classify as a special class.

Immutable is superset

Social class is a subset of immutable.

@FriendlyObligingState @CecileJudy Im in that same boat :/

@Princess.Beli Im still learning, but Id assume although it will frequently appear first. It by no means has to. The last question was a slight curveball. I initially thought the "not sustainable long term solution" was a conclusion, but after reading the full passage, it couldnt have been because it is not the final message the author ultimately wants to say.

For #2, I thought the "if the inflation drops" was another premises to the conclusion that follows. I see that its wrong but why?

Would the tiger argument be second because of the use of the word "can" or because it requires us to imply that tigers are mammals, or both (equally)?

All of my notes disappeared. I went to school the next day to find someone had one of my pages. Therefore, that person must have stole all my notes.
