To solve this analogy you need to rely on your knowledge of Greek roots. To begin with the prefix ichthy- means fish, so "ichthyology" is the study of fish. So, what is "ecclesiology" the study of? The Greek prefix ecclesi- means congregation, church. So, "ecclesiology" is the study of churches.

The prefix theo- means related to religion or to "God." So, "theocracy" is the rule of a government through "God" or the application of religious laws. To solve this analogy you need to determine what "autonomy" is the rule of. Well, auto- means "self," so "autonomy" is the ability to rule oneself.

The adjective bovine is used to describe characteristics displayed by or attributed to cows.

Cow is to bovine as dog is to canine as cat is to feline, etc.

"Bi-" and "duo-" are prefixes that both mean "two." A bicameral government is one with two branches, and a duet is a musical performance by two singers.

"Ante-" and "pre-" both mean "before;" both words refer to things that come before other things. "Post" means "after" and "script" refers to writing, so a postscript is an afterword.

Aquaphobia is the fear of water. Whenever you see the prefix ­­"aqua_-_," you can assume that the word will have something to do with water. So to solve this analogy, you have to determine what chronophobia is a fear of. Chronophobia has the same prefix as the word "chronological" (which has to do with the passage of time), so it would be reasonable to assume that the prefix "chrono-" implies a relationship to time. This line of thinking would lead you to the correct answer, that chronophobia is the fear of time or the passage of time.
