yeah! it's really me with my homework, you should try it!
the correct answer is b. so you can tailor your resumé to the position.
it is important before sending your resumé for you could add some extra information relating to former jobs that might you get a higher possibility to be hired.
may be the company is looking for an experienced person, and showing you have worked in the area they are looking a person for may give you more positive points!
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 !
