Which one of the following was not a common cause of death for concentration camp prisoners

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 !

caminas makes the most sense here since it means to walk.

when in the second paragraph fourth sentence it says "if youre" it should be "if you're"
