In an essay what do transitional tags like therefore and on the other hand connect?

her eyes water as she let her go

her mothers hand goes limp

face white and pale

lips blue and stale

she is gone

sadness fills her body

she collapses to her knees

as her mothers disease leaves the girl alone

the correct answer is option d. none of these. it is noted that options a, b, and c share the same content.

despite the valid answer provided at the last sentence of each of the options, a question/answer format shouldn't include humourous themed responses such as "you bet your thermal pj's we do." - unless of course, the answer is carried out in an informal environment. this could be replaced with a simple "yes" or "it is necessary".

the question should be re-phrased to a more appropiate syntaxis. instead of "do we need the greenhouse effect? ", it should be written as "is the greenhouse effect necessary? " in order to give it a general scope, instead of limiting the answer to the needs of "we" the humans.
