Final answer:
Benedick's aversion to marriage, highlighted in 'Much Ado About Nothing', is alluded to in terms of fears of infidelity and skepticism, but the excerpts provided don't contain his specific reasoning, which can be found in the original Shakespeare play.
Step-by-step explanation:
The specific reason Benedick gives in Much Ado About Nothing for not wanting to marry is not directly stated in the excerpts provided. However, in Shakespeare's play, Benedick jests about being a bachelor and voices his concerns about women being unfaithful, which may suggest his fear of cuckoldry and skepticism about the sincerity of women. These reasons contribute to his initial aversion to marriage, not a direct citation or quotation from the play. Unfortunately, without the exact text or context from 'Much Ado About Nothing,' a definitive reason from these excerpts cannot be provided. For an accurate depiction of Benedick's views on marriage, one should refer to the original play.
