1. How are senators elected? Is it by district or at-large?Explain.

Senators are elected at the state level, not by district. Each state has two senators, regardless of its population size. The senators are elected by the entire state, not by specific districts within the state. This means that senators represent the interests of the entire state, not just a particular district. The senators are elected through a statewide election, where voters across the state cast their ballots for the candidates. The senators serve six-year terms, with elections held every six years. This system was established by the U.S. Constitution to ensure that senators represent the interests of the entire state, rather than just a specific district.
