The author would MOST likely agree that Swift _________.

The most reasonable inference is the one that is closest to what is directly stated in the passage. The passage states in the second paragraph that Swift raised his questions “through satire” to “point out the underlying ridiculousness of the society around him.”
The other options are less likely. The author does not state that Swift believed that any attempt at human civilization should be abandoned. The author also does not state that Swift deliberately distorted historical facts for his own ends. Finally, the author does not state that Swift was not involved with the English government.
