The answer to which one of the following questions would most help in evaluating the columinist's argument?

A) How many books had each person surveyed read?

B) How many people chose books other than 1984?

C) How many people read the columnist's newspaper?

D) How many books by George Orwell other than 1984 was chosen?

E) How many of those surveyed had actually read the books they chose?

The answer is B. My reasoning is that since the columnists conclusion says that it 194 exercised much influece, by showing how many ppl chose books other than 1984, it would prove that it did have much influece. Is this correct? Thanks.
