(1)__________________________________________________________.But how do these polls actually work?Polls are surveys of a relatively small number of people compared to the actual number who will vote.They are an attempt to determine who may actually win an election in advance of the final vote.Let’s say that 100 million people are expected to vote in the general election.If 100 people are asked for their opinions,each respondent represents a million voters.Obviously, the results of such a poll are not very reliable.The more people surveyed, the more meaningful are the results.(2)_____________________________________.They try to find a representative variety of people to question.For example, they look for people with similar backgroundsand from similar regions to those of all the voters.Pollsters also ask questions that try to determinehow many people who support each candidate will actually vote. If a candidate has a higher percentage of enthusiastic supporters than his opponent,he has a better chance of winning than the simple numbers might suggest. Pollsters may only count those who they consider to be “likely voters”.Polls often ask potential voters what they like or dislike about each candidate.The campaigns use those results to help them decide which issues to stress or which positions to clarify.(3)_____________________________________________. But they can give important clues as to where things may be heading.At the very least, if you like politics, polls can be great entertainment.
