What is the name of the section where the listing of unit-dose system is given ?

Sectionalism generally means being loyal to only a part, instead of the whole.

Explanation:

Examples can be seen more in a country term, taking the US for example. People in California may be more loyal to California and may put state priorities in front of national securities. Another example can be the South, which mostly contain rural townspeople and farmers, and they may be loyal to only politicians who can support their way of life. This is a "section" of people who are only loyal to a person because of such & such benefit.

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 !

showing or having an insensitive and cruel disregard for others. (so basically being heartless)

hope this : )
