- "chilles is sad and angry because hector, the trojan leader, killed his best friend patroclus. he seems angry with himself because he didn't or protect patroclus against the trojans."

the answer is subjective. i personally agree with the first answer for this question.

if one isn't strictly talking about objects then the correct answer would be 'my eyes' since according to this riddle i am asleep and in order to answer/open the door i need to open my eyes first of all.

however, if one is specifically looking for an object, then the first thing i would open would be the door

hope this !
