BigBook Test 12 question

in this question the : supports the idea . I am not sure which idea it supports

  • the misconception that sentence structure ~ thought → which means that blank should have a word like complex
  • Or the entire sentence in the left → which means (sentence structure !~ thought ) which means that even if sentence str is complex should not impact the idea

can someone pls explain how it is the former and not the latter ?

We would need a contrast word like “however” for the second interpretation to work.

Also, given where the blank sits in the sentence, you can’t really fill in anything to make it match the second interpretation.
