The answer is option C "They have lower voter turnout than presidential elections"
Explanation:
Elections for government federal offices are held in the US twice a year. Since the president of the US is chosen for a long term period, one of these election will happen in the President's long term of office. It is these decisions that are known as "midterm elections."During a midterm political race all the 435 individuals from the Place of Agents are on the ballot and 33% or at least 30 of the 100 individuals from the Senate.
The explanation as to just a single third of the Senate is on the ballot is that Representatives serve long terms of office and the writers of the Constitution needed to guarantee that they were not all moved out at one time.
The delegates elected George Washington to preside over the Convention. 70 Delegates had been appointed by the original states to attend the Constitutional Convention, but only 55 were able to be there. Rhode Island was the only state to not send any delegates at all.
