Literature is studied as a subject at school  because

Step 1: Analyze the question The question asks for the main reason Literature is studied as a school subject. This is about the purpose and value of literature in education.

Step 2: Explain the concept Literature (drama, prose and poetry) mirrors human society. Through characters, conflicts, themes and settings, students see issues such as love, betrayal, corruption, justice, death, and morality. This helps them understand life, develop empathy, think critically, and learn values. Entertainment and language skills are benefits of literature, but they are secondary to its main educational purpose.

Step 3: Evaluate each option

• A. It exposes students to the realities of life. This is correct. Literature is often called a "mirror of society," and studying it helps students understand human experiences, social problems and moral lessons.
• B. It provides entertainment. Literature can entertain, but this alone does not justify its place as a school subject. Entertainment is a function, not the main academic reason.
• C. It merely gives additional work to students. This is clearly wrong, because no subject is designed just to add workload.
• D. It teaches the use of words. Literature does improve vocabulary and style, but that is the focus of the English Language subject. It is a by-product of literature, not the core reason.

Step 4: Identify the answer

Step 5: Exam tip For "why is literature studied" questions, look for the option about life, society, values, or human experience. Options with words like "merely" or "only" are usually traps. Remember: Literature = mirror of life.
