Which logical fallacy is used in the text?
Did you really vote for Ken as class treasurer? Didn't you hear that his uncle was imprisoned for embezzling $1.5 million?

 - guilt by association: a negative association intended to discredit someone or something
 - false dichotomy: an argument that presents only two choices when more options exist
The text argues that Ken can't be trusted with money, because his uncle embezzled money. However, even though his uncle couldn't be trusted with money, that doesn't necessarily mean that Ken can't be trusted with it. This illustrates a type of logical fallacy known as guilt by association.
