Channel 7 news sent pollsters downtown to ask people this question: Do you watch Channel 7 news at least 3 nights per week, from Monday to Friday?

The next day they advertised in the newspaper that, according to a poll, "More people watch Channel 7 news than any other channel." How might these results have been influenced by the way the pollsters asked their questions?
A.
They sent pollsters out into public to poll people, and polls of this type should be done on the telephone.
B.
People downtown likely watch more news, so this skewed the result.
C.
They should have polled more people.
D.
The pollsters narrowed the question to Monday to Friday, which is 5 days. "Three nights a week" would not have been a majority if they considered a full week as 7 days.
