Article: The Earth has warmed by about half a degree(0.50degC)over the last 100 years. It could be getting warmer on its own, but many scientists think that people are making the Earth warmer by making a greenhouse effect. The greenhouse effect is important. Without it, the Earth would not be warm enough for us to live on. But just a little warmer than it is now could cause problems for humans, plants and animals. Many of the things we do every day can change the Earth's temperature by sending greenhouse gases into the air. We send greenhouse gases into the air when we watch TV, turn on lights, dry hair, play video games, wash or dry our clothes or drive cars. The rubbish from factories and homes also produces greenhouse gases. Even a small change in temperature can affect our weather. This can cause changes in the sea levels, the air, flooding, and our fresh water. The change in the temperature can also cause changes in the living places for animals and plants, endangering many animals. Global warming is a big problem, and every little bit we do can help. We can save electricity. We can save energy in other ways such as by taking buses or walking rather than driving cars. We can recycle to reduce the rubbish and save natural resources such as trees, oil and metals. We can buy products that don't do bad to the environment and we can turn to solar energy. Remember the little bit that you do will bring a better world. Question: In this passage, the scientists are mainly trying to make the readers realize _ . Yes or no, is the answer "humans are making the earth warmer"?
**Answer**
No

Article: A wild baby bison at Yellowstone National Park had to be killed because of tourists. The tourists thought that the baby bison looked cold. They put it in their car and drove to a park ranger station. A ranger described the action of the tourists as a "dangerous move" because adult bisons can look after their babies very well and they will attack to protect their young. Park rangers took the animal from the car and set it free. But, sadly, the baby was refused by its family because it had the smell from humans. Yellowstone National Park explained on Facebook that the smell from people can cause parent animals to refuse to accept their young. The park tried again and again to make the baby bison lives with its parents. After several times they had to give up. Many people expressed anger at both the tourists and the park. The park said that they did not have the ability to care for a young bison. They also said that it is "not the task of the park to save animals". The tourists were fined $110 for touching park wildlife. Park rules say that visitors to Yellowstone should stay at least 22 meters away from all wildlife, and at least 90 meters away from bears and wolves. One ranger said that Yellowstone recently added many safety signs that say staying near the wildlife there is dangerous to humans and animals as well. Those signs are written in English and other languages. Question: The park ranger described the action of the tourists as a "dangerous move" because _ . Yes or no, is the answer "adult bisons would attack the tourists"?

Article: Dear Mrs. Smith, I was a students of yours in Grade Six, and I hope you still remember me. I'm writing this letter because I want to let you know that the school year with you was important and special to me. It made a big contribution to my life. I know I was very quiet in your class, and you never said much to me. But you did something that made a big difference in my life. You see, all through my first year in school, I hated to read. Books were just words that had very little to do with me, and I was bored by them. I'll never forget the first day of Grade Six when you took out a thick book and began to read the story to our class. Your voice seemed to change with the people in the story, I couldn't wait until after lunch when you would read to the class. You read us all kinds of wonderful books. During the summer after my year in your class, I missed hearing the stories you would read. So one day I picked up a book and read it all on my own. I found out that I could make the words interesting, too. I love to read! Thank you for opening the world of books for me. Yours, Jenny Question: Jenny was not sure if(="whether)" Mrs. Smith could remember her because _ at school. Yes or no, is the answer "She had few words."?
