Final answer:
The conjecture is that your cousin is at least 18 years old since they can vote, in accordance with the 26th Amendment. Voter turnout among younger people may be improved through various strategies, with age affecting voting behavior due to different levels of engagement and responsibilities.
Step-by-step explanation:
A conjecture using the provided information would be that since your cousin can vote and based on the age requirement, it's likely that your cousin is at least 18 years old. The 26th Amendment of the United States Constitution states that the right to vote cannot be denied to citizens who are eighteen years of age or older. This was a significant change made in 1971, allowing a larger portion of the population to participate in the democratic process.
Increase in voter turnout could involve strategies like moving to all-mail voting, holding elections on weekends, or automatic voter registration. Age affects voting likelihood due to factors including political engagement and social responsibilities. To predict whether classmates would vote, one might ask about their age, educational level, and interest in politics.
The voter turnout in younger demographics is often lower than that of older age groups, possibly due to feelings of disenfranchisement or a belief that their votes do not matter. Changes in voting laws, like those in Austria and Brazil where the voting age was lowered even further, reflect the dynamic nature of civil rights and the ongoing evolution of suffrage based on societal values and external factors.
