What do i call the daughter of my step mother?

Ineed simplifying this thesis and making it easier to understand for the reader (more concise) "no matter how religious one may be, one’s faith tends to change under unexpected and challenging circumstances."

In a group discussion, which statement most clearly uses evidence to support a conclusion? a) the author makes some good points, but i feel that he’s ultimately biased. b) the author proves that he’s biased when he uses terms like “silly” and “stupid”. c) the author obviously hates the way fast food tastes, which is why he’s negative. d) the author first criticizes fast food, and then goes in to criticize junk food.

Besides the revisions listed in the paragraph, what else can deepak do to strengthen his paper?
