102.  But if you replace the books with a literal one, I believe they will drowse in no time.

103.  They look like no one but a student majoring in natural science, however, in our room there are only social science girls.

104.  From all these, I can draw the conclusion that no one can be simply allocated into a certain group.

105.  All the features should be taken into account before considering such a "group" or "community".

110.  It's not fair to make such a list about someone without knowing him further.
