When does Buck learn to rely on his instinct? When Buck is traveling from his original home
When he experiences the dangers in the Yukon
When he gets to roam around with John Thornton
When Buck needs to pull the sled alone

i think it's either 'to expose the corruption of the communists in russia', or 'to criticize animal brutality by communists in russia.'  

hope this ! : )

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 !
