In my country, the system to access university includes a philosophy exam that works similarly. You are given a text to understand, summarise, discuss, and compare with a different author. They are testing for reading skills, reasoning and expression, so there is no good answer - knowing the works of different authors just makes it more likely that you'll know some ideas similar to the text at hand, but if you don't happen to know something similar you can, say, get a text by Marx and compare it to Plato, as long as you make a decent argument on the connection.
