Article: A recent survey of 2000 parents in Britain showed that they are often afraid of science questions asked by their curious children only because they have no idea what the answer is. Here is a list of some simple questions that you can ask your parents to see if they know the answers. Q: Why is the sky blue? A: You probably know white sunlight is made up of seven colors. While it moves in a straight line when going through space, it starts to divide as it hits "raised area" in the atmosphere. The ones with longest wavelengths pass through easily. The blue , however , can be taken in by the gas molecules because it has a shorter wavelength , which in turn scatters it in different directions. That's why when you look up at the sky, it appears to be blue. Q:Why does the moon sometimes appear during the daytime? A: The simple answer to that is because just like any other object it is being lit by the sun. As long as it is around 45 degrees or even 90 degrees off the sun, it will receive light and be able to be seen. The only time it is not able to be seen during its 28-day orbit around the earth is when it is right between the earth and the sun. That's because its back , which is not lit by the sun, is facing us. Q: Where do birds/ honeybees go in winter? A: While the bird part is quite easy, since a lot of them get together and travel, the honeybee part is likely to puzzle your parents. It turns out that these busy insects stop being that active when the temperature drops below 50degF. Instead ,they get together in the lower central area of the hive and form a ball around their queen. This helps keep both warm enough to survive the cold winter months. Question: What do honeybees choose to do when the temperature drops below 50degF? Yes or no, is the answer "They choose to keep themselves warm."?

Article: The food in White Rose Restaurant was cheap and good, but nobody seemed to want to eat there. There were very few people going to eat there. The owner was very worried about it. Then he thought of a good idea. A few weeks later, his restaurant was always full of men and their girlfriends. Whenever a gentleman came with a lady, a kind waiter would give each of them a beautiful menu. The menus looked exactly the same on the outside, but there was an important difference inside. The menu that the waiter handed to the man gave the correct price for each dish and each bottle of wine, while the menu that he handed to the lady gave a much higher price! So when the man calmly ordered dish after dish and wine after wine, the lady thought he was much more generous than he really was! The man could make a good impression on the lady. Question: When a gentleman and his girlfriend went into the restaurant, the waiter would give _ a beautiful menu. Yes or no, is the answer "each of them"?
**Answer**
No

Article: Many years ago, when I was working as a volunteer at a hospital, I got to know a little girl named Lisa. The poor little girl had a very serious disease and was dying. The doctor had done his best but no medicine really worked. The only chance to save her seemed to be a blood transfusion from her five-year-old brother. The little boy had the same disease before and had developed the antibodies to fight the illness. The doctor talked to the little boy about what they planned to do, and asked him if he would be willing to give his blood to his sister. I saw him hesitate for a moment. He took a deep breath and said, "Yes, I'll do it if it can save Lisa." As the transfusion was going on, the little boy lay quietly in bed next to his sister. He looked at her and smiled all the time. When everything was done and the colour returned to his sister's face, his smile disappeared and he looked a little afraid. He looked up at the doctor and asked, " Will I start to die now?" He was too young to understand the doctor. He thought he would have to give all his blood to his sister, but he agreed. Question: How did the five-year-o1d boy understand the doctor's plan? Yes or no, is the answer "He thought he was going to lose all his blood."?
**Answer**
No

Article: I had a very special teacher in high school many years ago. Her husband died of a heart attack. About a week after his death, she shared some of her insights with us. The class was nearly over. She said, "Before class is over, I would like to share with all of you an important thought." "Each of us is put here on Earth to learn, share, love, enjoy and give all by ourselves. We must make the best of every single day." Her eyes were beginning to water and she went on, "So I would like you all to make me a promise. From now on, on your way to school, or on your way home, find something beautiful to notice. It doesn't have to be something you see -- it could be a nice smell -- perhaps of freshly baked bread, or it could be the sound of the breeze slightly blowing the leaves in the trees." "Please look for these things, and love them. For, although it may seem common, these things are the stuff of life. They are the little things we are put here on Earth to enjoy. They are the things we often take for granted. We must make it a point to notice them, for at any time it can all be taken away." The class was completely quiet. We picked up our books and went out of the room silently. That afternoon, I noticed more things on my way home from school than I had that whole term. I usually think of that teacher and try to enjoy all of those things that we sometimes overlook . Take notice of something special you see during your lunch hour today. Walk barefoot along the beach at sunset. For as we get older, it is not the things we did that we regret , but the things we didn't do. Question: The high school teacher shared her insights with her students _ . Yes or no, is the answer "at the end of class"?
**Answer**
Yes
