Which statement is an example of the author's use of logos that might be used in an argument?

'Logos' in Literature, can be simply defined as an appeal to logic. It's a device (a tool) used by writers (and implicitly by common people in everyday speaking).

It is one of the three called 'Aristotelian appeals' (Logos, Ethos, and Pathos). The most important thing to know about them here is that they all serve a common purpose: Prove the author's argument. Logos aims to do this through logic.

So usual characteristics of this tool are the use of facts, statistics, etc. (Please note that the sole use of these elements does not characterize Logos. Logos appears when these elements are used, again, to sustain an argument.)

Therefore the best answer would be letter B. As by stating his firsthand experience, the author tries to legitimate any argument he proposes after that.

The following statement is an example of the author's use of logos that might be used in an argument:
