Explanation:

Option 1: the passage does not talk about Copan inhabitants destroying the records.
The first paragraph mentions that “detailed archaeological studies are available for some Maya sites” which contradicts options 2. Further, since there is no other evidence in the passage, we have no ground for option 3.
Option 5 is mentioned in the third paragraph; however, it does not explain the reasons for Maya collapse.
The passage mentions five possible strands for the Maya collapse. The passage states, “I acknowledge, however, that Maya archaeologists still disagree vigorously among themselves - in part, because the different strands evidently varied in importance among different parts of the Maya realm; because detailed archaeological studies are available for only some Maya sites; and because it remains puzzling why most of the Maya heartland remained nearly empty of population and failed to recover after the collapse and after re-growth of forests”. The summary of this paragraph is option 4.
Hence, the correct answer is option 4.
