You couldnt survive without your skin. It has many important functions. The main function of the skin is controlling what enters and leaves the body. It prevents the loss of too much water from the body. It also prevents bacteria and other microorganisms from entering the body. The skin helps maintain a constant body temperature. It keeps the body cool in two ways. Sweat from sweat glands in the skin evaporates to cool the body. Blood vessels in the skin dilate, or widen. This action increases blood flow to the body surface. This allows more heat to reach the surface. The heat is then able to radiate off the body. The opposite happens to retain body heat. Blood vessels in the skin constrict, or narrow. This decreases blood flow to the body surface. This reduces the amount of heat that reaches the surface. When this happens, less heat can be lost to the air.

Response: yes

Simply put, energy is the ability to a cause change. Energy can cause many types of change. Think about when you have a lot of energy. You are able to do a lot of things. When you dont have a lot of energy, you may sit around and do very little. A similar thing happens to particles of matter as energy is added. The more energy there is, the faster the particles of matter move. Energy is also the reason you are able to move around. In fact, matter is always in motion. It can even change from one form to another. For example, electrical energy can be converted into heat energy. You see this every time you use the toaster. Energy causes a change in matter when you lift your arm. Energy can be used to move matter. You use energy to take a step to move forward. Thanks to energy, your body moves. The energy of moving matter is called kinetic energy.

Question: "True or false. Matter is able to change forms despite, usually, not being in motion?"

Response: "True"

Problem: We drove about a great deal--the country at the back of Deauville, going away from the sea, is lovely--very like England--charming narrow roads with high banks and hedges on each side--big trees with spreading branches meeting overhead--stretches of green fields with cows grazing placidly and horses and colts gambolling about. It is a great grazing and breeding country. There are many haras (breeding stables) in the neighbourhood, and the big Norman posters are much in demand. I have friends who never take their horses to the country. They hire for the season a pair of strong Norman horses that go all day up and down hill at the same regular pace and who get over a vast amount of country. We stopped once or twice when we were a large party, two or three carriages, and had tea at one of the numerous farmhouses that were scattered about. Boiling water was a difficulty--milk, cider, good bread and butter, cheese we could always find--sometimes a galette, but a kettle and boiling water were entirely out of their habits. They used to boil the water in a large black pot, and take it out with a big spoon. However, it amused us, and the water really did boil.

Question: "The big Norman posters are in demand in the back of which country?"

Answer: "Deauville"

OPTIONS:
- no
- yes
Answer: yes

Question:
Plants also detect the daily cycle of light and darkness. Do you know how plants respond to these changes? Some plants open their leaves during the day. It is during these hours the plant can collect sunlight. At night, the plant closes its leaves to prevent water loss. Many plants respond to the change in the length of the day. As days grow shorter, some plants respond by going dormant. Dormant is when a plant suspends its growth. It does this in order to survive. Shorter days signal the coming of winter. Winter in most areas means extreme cold. It is also very dry in the winter months. As winter approaches, some plants respond by their leaves changing color. After the change in color, they fall off. This dormancy period helps trees. It allows them to survive the cold and dry winter. Plants only want to grow when conditions are right. After reading the above, is "It stops growing" the correct answer to the question "What happens to a plant when it goes dormant in order to survive?"? OPTIONS:
- no
- yes

Answer:
yes

Input: Convicted murderer Seth Baxter awakens chained to a table beneath a pendulum blade . A videotape informs him that crushing his hands between the presses will release him ; he does so , but the blade still swings down and violently cuts him in half , while someone watches through a hole in the wall . The scene cuts to Agent Peter Strahm , who kills Jeff Denlon in self-defense and is sealed in the sickroom . He finds a hidden passage with a tape recorder that warns him to stay in the sickroom , but ignores it . He is attacked by a pig-masked figure in the passage and awakens with his head sealed in a box slowly filling with water , Which he survives by performing a tracheotomy using a pen . Outside the plant , Detective Mark Hoffman delivers Corbett Denlon to the police and claims they are the only survivors , and is shocked when Strahm is brought out alive as well . Jill Tuck is met by John Kramer's attorney , who is administering his will . She is left a box and a videotape , in Which John stresses the importance of the box's contents . She opens it with a key hung around her neck and then leaves without disclosing its contents .

Sound waves are mechanical waves. They can travel only through matter. They cannot travel through empty space. This was demonstrated in the 1600s by a scientist named Robert Boyle. Boyle placed a ticking clock in a sealed glass jar. The clock could be heard ticking through the air and glass of the jar. Then Boyle pumped the air out of the jar. The clock was still running, but the ticking could not be heard. Thats because the sound couldnt travel without air particles to transfer the sound energy. Is there any other place where sound cannot be heard? Here is a hint: is there any other place that does not have air molecules? Thats right, in space sound cannot be transferred. So can astronauts hear each other? Yes, they can, because they are in enclosed space stations or pressurized suits.In both cases, they are surrounded by air molecules. If they left their space ship and did not use their electronics, they would not be able to hear each other. Next time you watch a science fiction movie, think about this factoid. When spaceships are destroyed by hostile alien beings, there would be no sound heard. Sound waves can travel through many kinds of matter.

Question: "Can sound waves travel through empty space?"

- no
