Answer:
A. Voters in states with late elections knew the results of early elections.
Step-by-step explanation:
The reason why this system of voting was discouraged was that towards the end of the 34-day period those who voted late could determine who will likely win from the results of those who voted early. That way, they would be able to galvanize themselves to influence the eventual winner of the election.
The agrarian nature of the American societies as well as the reason stated above were contributory factors to why the United States changed the voting day to a Tuesday in November.
