What can be inferred about the cyclops?

he lives in fear of zeus and all the rest of the greek gods.
he sided and fought with the trojans during the war.
he is eager to provide food and shelter to his guests.
he does not live by the same rules and customs as the greeks.

It can be inferred that the Cyclops does not live by the same rules and customs as the Greeks. 

This is easy to comprehend what he did to Odysseus and his men. He was going to eat them therefore we can see he was not very hospitable and hospitality was very important to the Greeks, especially to the God's.

The correct answer is D,) He doesn't go by the same customs , etc

The Cyclops doesn't like company , he will eat his guests. He does anything that he wants to except disobey the gods rules.

He was going to eat Odysseus and his men , he ate most of them already. 

I really hope that this helps you.
