Step-by-step explanation:
The statement that best summarizes the ideas in this passage is that states have different deadlines and requirements for citizens to register to vote. Voter registration in the United States is primarily the responsibility of the states, with federal laws setting certain limits and requirements. The process of registering to vote varies from state to state and may involve residency requirements, citizenship confirmation, and identification. While some states provide for online voter registration and automatic registration, others still prefer traditional methods due to concerns about fraud and security.
In efforts to promote higher voter turnout, governments have been working to make registering easier, such as through online registration systems or by making it part of other government service applications. Despite these efforts, the complexity of voter registration can still present a barrier to some citizens, particularly among different age groups, educational levels, and socio-economic statuses.
