Question

read the excerpt from jacksons blog. learning to speak a new language is one of the best decisions i ever made! this summer, i traveled throughout japan with my robotics team and was able to communicate with almost everyone we met. next year, im planning to live in japan as an exchange student. i think it will help me improve my japanese reading and writing skills. i hope all my friends get inspired to learn a language, too! the purpose of jacksons blog is to ○ advertise foreign language lessons. ○ entertain with humorous anecdotes. ○ persuade readers to learn a language. ○ teach readers how to speak japanese.

Explanation:

To determine the purpose, analyze the excerpt: Jackson shares positive experiences of learning a language (travel, communication, future plans to improve), and hopes friends get inspired. "Advertise" is wrong (no lessons ad). "Entertain" is wrong (no humorous anecdotes). "Teach how to speak" is wrong (no teaching steps). "Persuade" fits as he shares benefits to inspire others to learn.

Answer:

C. persuade readers to learn a language.
