Hãy chọn đáp án đúng để trả lời những câu hỏi dưới đây.

I am Thinh. My family has four members: my father, my mother, my sister and me. We live in the city and we’re all enjoying our busy lives.

My father is a doctor. He is responsible for examining, diagnosing and treating patients in the hospital. My father is a warm-hearted person. He’s never angry with us. His work often starts at 8 a.m. and finishes at 6 p.m. However, he sometimes has night shifts. Sometimes he spends the whole day in the hospital, taking care of patients.

My mother is a receptionist at a famous hotel. She works fewer hours than my father. She usually starts work at eight o’clock in the morning and comes back home at six in the evening. After work, she cooks, does the housework and helps me with my homework.

Although there are four members in my family, only three of us are living together. My sister, Chi, is an undergraduate student at Hanoi National University so she is studying in Hanoi. She comes home once a month and sometimes twice or more.

I’m 16 and I’m a student. I go to school six days a week and have five periods a day. I also have to deal with a lot of tests every week and it takes me plenty of time to prepare for them. My sister seems to have more free time than me. That’s why I want to become an undergraduate student like her.

My family has little time to gather and talk to one another, so we find long vacations such as a summer vacation or Tet holiday valuable. We spend the whole day at home, decorating our house, cooking meals and watching our favorite TV programs.

A. Because she seems to have less free time than him.

B. Because he seems to have more free time than her.

C. Because he has a lot of tests to prepare for.

D. Because he wants to have more free time.
