Q: Read the following article and answer the question. Article: One day, a man found the cocoon of a butterfly and he brought it home. A few days later, the man saw a small hole in the cocoon. He sat and watched for several hours as a butterfly struggled to force its body through that little hole. Then it stopped. So the man decided to help the butterfly. He took a knife and cut a bigger hole in the cocoon. The butterfly came out of the cocoon but it had a weak body and small, thin wings. The butterfly didn't start to fly. In fact, the butterfly spent the rest of its life crawling around with a weak body and thin wings. It was never able to fly. The man acted with kindness but he didn't understand that he had done something wrong. When a butterfly crawls out of the cocoon, it must struggle. The hard work of getting out of the cocoon forces the fluid from the butterfly's body into wings. It helps the butterfly be ready to fly. If the butterfly never has to force itself out of the cocoon, its wings never get the fluid and it can never fly. Sometimes struggles are exactly what we need in our lives. If we lived our lives without any problems, we would never learn or grow. We would not be as strong as we could have been and we would never fly. So, the next time you are faced with a challenge or a problem, remember the butterfly. Struggle a little - then fly! Question: Why did the man cut a bigger hole in the cocoon? Answer:

OPTIONS:
- To catch the butterfly easily.
- To play with the butterfly.
- To help the butterfly come out.
- To make the butterfly stronger.

A: To help the butterfly come out.

Unluckily, a lot of food that looks good may have pollution. Where is the pollution from? It has something to do with how people produce food: growing it on the farm, processing it in factories, and making it ready for you to eat. Here's what happens: Most farmers use chemicals to stop their crops from getting sick. Many of these chemicals remain in the food that you eat. Some people believe this may cause cancer. These chemicals may also pollute water and air, and kill animals and even people by accident. Most drinks are just flavored water . Every drink coming in plastic bottles which you then throw away means a waste. Sugary drinks make you fat. In the factories, much of what you eat and drink gets messed. Often things are put into food to make it delicious and look good but they might be harmful to people. And some food like meat often gets polluted by bacteria. What you can do: Try to get organic food. Organic food doesn't have any ingredients that are bad for the land, air or water. Don't eat processed food or drinks. Eat fresh food whenever you can and cook at home. Question: Which of the following processes cannot make the food be polluted? Answer:
