13. What is one responsibility that is only for U.S. citizens?

Answer: A

Explanation:

Serve on a jury

One responsibility that is exclusively for U.S. citizens is serving on a jury. This civic duty is fundamental to the American judicial system and is a privilege that only citizens can undertake.

A) Serve on a jury

This option is correct because serving on a jury is mandated by law specifically for U.S. citizens. It is a key component of participating in the judicial system and ensuring a fair trial, which reflects the rights and responsibilities that come with citizenship.

B) Pay taxes

While paying taxes is a responsibility for all residents in the U.S., it is not limited to U.S. citizens. Legal residents and non-citizens may also be required to pay taxes on their income, making this option incorrect.

C) Obey the law

Obeying the law is a responsibility that applies to everyone living in the United States, including both citizens and non-citizens. Therefore, this option does not pertain exclusively to U.S. citizens and is incorrect.

D) Attend school

Attending school is a requirement for minors in the U.S. and applies to all children, regardless of citizenship status. Thus, this responsibility does not uniquely belong to U.S. citizens, making it an incorrect choice.

E) Drive a car

Driving a car requires a valid driver's license, which can be obtained by both citizens and legal residents. This responsibility does not exclusively apply to U.S. citizens, so this option is incorrect.

F) Get a job

Getting a job is a general responsibility that can apply to both U.S. citizens and legal residents. As such, this choice does not reflect a duty exclusive to citizens and is therefore incorrect.

G) Buy health insurance

Buying health insurance is a requirement for many individuals in the U.S., but this obligation applies to both citizens and legal residents. Therefore, this option is also incorrect.

Conclusion

In summary, serving on a jury is the only responsibility listed that is reserved for U.S. citizens, highlighting the unique civic role they play in the judicial process. All other options either apply to non-citizens or do not represent responsibilities exclusive to citizenship.
