Question II Read the passage and answer the questions.
Visual pollution has a greater effect on people than you may think. I remember when I went to a big city, I was really scared because so much graffiti on the buildings' wall. Then I looked up, and I saw a lot of power lines over my head. Although they were not dangerous, I still felt unsafe since I thought they might fall down. These things prevented me from enjoying the beautiful sights of the city.
I also remember the time when I was a student at a university. Once I was so busy with my assignments that I did not tidy my room for two weeks. Looking at the messy room caused me so much stress that I did not want to study. Then I decided to clean the room and put my thing in their proper places. I also bought a small plants and placed it in a corner of the room. These simple actions increased my motivation and helped me to focus on my learning.
Questions.
1.How did the author feel when she saw the power lines?
 .
2.Why did she have that feeling?
3. What was she busy with?
4. What happened when she looked the messy room?
5. What did she do for her room?
