Raul: The disturbing reality is that 85 percent of individuals now report that they know at least one individual who has spent at least one year in prison.

Stefano: But suppose that any given person knows about 40 other people. If about 5 percent of the population, or about one out of every 20 individuals, has spent at least one year in prison, then any given person probably knows multiple people who have been imprisoned for at least one year.

Stefano's argument relies on the assumption that ____.


(A) for the population in question, reasonable rates of imprisonment with one-year sentences are not generally exceeded your answer

(B) individuals who have never been imprisoned for one year or longer do not associate only with other individuals who have never been imprisoned for one year or longer correct

(C) at least 85 percent of the population in question is always comprised of people who know at least one person who has been imprisoned for at least one year

(D) Raul is not intentionally manipulating the numbers he uses to support his assertion

(E) first-hand knowledge of the prison system motivates individuals to stay out of prison more than do statistics about the percentage of the population that has been imprisoned for at least one year

Conclusion: Any given person probably knows MULTIPLE people who were in prison 1+ years.

Evidence: 5% of population has spent 1+ years in prison (1/20 people). 85% of people say they know at least 1.

Assumption: Ex-cons don't only know other ex-cons; people w/no record don't only know people w/no record.

Notice how Stefano's argument relies on WHO "any given person" knows. That must be part of the correct answer.
