Which word in the sentence is the object of the preposition? the movie hero boarded the moving train and went into a dark tunnel. a. dark b. tunnel c. train d. hero

a source card is mage during research to tell the facts about the source one is using.

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 !
