You might infer from the substantial growth of the united states army and navy during the civil war that (choose more than one answer.)

a. the civil war strengthened the american armed forces

b. better training and equipment methods were developed

c. the navy overpowered the army

d. the civil war did not consider the u. s. armed forces a priority

the strategies is fictional storied

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 !
