Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the best answer to each of the following questions from 31 to 40.

In today's modern society, many people face economic challenges due to rising living costs and rapid changes brought by modernization. [I] Basic necessities such as food, clothing, and other daily expenses continue to increase, placing pressure on families. [II] As a result, some students choose to take on part-time jobs to support themselves and ease their parents' burden. [III] From a positive perspective, working part-time offers numerous valuable benefits for students. [IV]
One major advantage is that part-time work helps students use their free time productively. Instead of engaging in negative activities, such as unhealthy social behaviors, they can spend their time working in places like restaurants or shops. Although balancing work and study may initially be challenging and exhausting, students eventually realize that their efforts are worthwhile and beneficial for their personal growth. As the Malay proverb goes, “Rowing upstream, swimming to shore, suffering first, and enjoying later.”
In addition, part-time jobs help students develop essential life skills. Communication skills are enhanced through daily interactions with customers and coworkers. Furthermore, they also gain practical experience such as teamwork, customer service, and problem-solving. These experiences not only prepare them for future careers but also boost their self-confidence.
Financial benefits are another important reason students take part-time jobs. Some individuals work to keep the wolf from the door or to cover necessary expenses such as tuition fees, rent, or transportation, while others earn extra money for personal use. Regardless of their purpose, earning their own income teaches them how to manage money wisely, save for the future, and become more self-reliant. This also reduces the financial pressure on their families.
Finally, working part-time encourages students to develop discipline and a strong sense of responsibility. They must manage their time effectively to balance work, study, and rest. This ability not only contributes to academic success but also prepares them for future challenges in both their personal and professional lives.
In conclusion, part-time jobs provide students with opportunities to use their time properly, improve skills, gain financial independence, and develop strong discipline. These experiences not only shape their character but also lay a solid foundation for a successful and independent future.
