  3. In 2015, according to a news channel, 30 percent of the voters had inclination towards party “A”. In 2017, this figure rose to 36 percent.But in another poll, the percentage was low to 32 percent. Therefore, the party “B” is likely to win next elections. Which of the following seriously weaken the above conclusion?
    It has been showed that 79 percent of voters belonging to party “A” vote in an election as compared to 75 percent of voters belonging to party “B”
    People like to switch their votes at last minute
    No one can predict how much people will vote
    31 percent of people favore party “B”
    none of these
    Option D
    The conclusion drawn in the pasage talks about party B likely to win.Obviously if we know that only 31 percent of people favour party B,party A will win election-as the estimates for how many people support party A varies from 32 to 36 percent.Even,in worst case, for party A ,party B would still not be likely to win election.
