Problem understanding the logic of this verbal sentence

Read this thread and tell me if it answers your question:

Can someone pls help with my math stratergy thinking

Well, they’re part of the same idea chunk, but only one portion of the idea applies specifically to blank 1. The “recent eruption” is more of a set up for blank 2, along with “violent nature”. But ultimately, this is one of those questions where it’s best to think about the sentence holistically–both blanks play off each other and require us to use the same clues to solve both.
