In the week before a local election, a news company polled registered voters in the area to ask them which candidate they planned to vote for. Voters from a representative sample of genders, ages, races, and political affiliations were polled, and 53% of them said they would vote for incumbent Jana Reyes for mayor over any other candidate. Based on the poll results, the news company concluded that Reyes would win the mayoral race.
Each of the following, if true, could weaken the conclusion presented above except:
A. The news company conducted the poll by phone, mainly in the middle of the day over two weekdays.
B. This race has been a particularly tumultuous one in which public opinion has often turned very quickly.
C. In this town, any mayoral race in which the top candidate receives less than 55% of the vote will result in a runoff election.
D. In the past, polls given by the news organization that showed more than a 5% lead by a particular candidate have predicted the outcome of the race with a high degree of accuracy.
E. Due to an administrative error, Jana Reyes will be a write-in candidate on the ballot in the actual election.

This is an except question, therefore anything that will make the the conclusion more likely is the answer. Anything above 5% difference means that mayor will win. 53% -47%(2nd candidate) =6% difference, hence a likely victory based off the polls.
