Theo kế hoạch một công nhân dự định làm 100 sản phẩm trong thời gian đã định. Nhưng thực tế, do áp dụng khoa học kỹ thuật nên đã tăng năng suất 4 sản phẩm mỗi giờ do đó không những hoàn thành trước thời hạn 25 phút mà còn vượt mức 10 sản phẩm. Hỏi theo kế hoạch mỗi giờ người đó làm được bao nhiêu sản phẩm?

Visual pollution has a greater effect on people than you may think.
I remember when I went to a foreign city, I was really scared because there was so much graffiti on the buildings' walls. Then I looked up, and I saw a lot of power lines over my head. Although they were not dangerous, I still felt insecure since I thought they might fall down. These things prevented me from enjoying the beautiful sights of the city.

I also remember the time I studied in Melbourne. 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 things in their proper places. I also bought a small plant and placed it in a corner. These simple actions increased my motivation and helped me to focus on my learning.
What about you? Have you ever been affected by visual pollution?
