Problem: If you have a mass of 50 kg on Earth, what is your weight in newtons? An object with more mass is pulled by gravity with greater force. Mass and weight are closely related. However, the weight of an object can change if the force of gravity changes. On Earth, the force of gravity is the same everywhere. So how does the force of gravity change? It doesnt if you stay on Earth. What if we travel to another planet or moon in our solar system? Look at the photo of astronaut Edwin E. Aldrin Jr. taken by fellow astronaut Neil Armstrong in the Figure. They were the first humans to walk on the moon. An astronaut weighs less on the moon than he would on Earth. This is because the moons gravity is weaker than Earths. The astronauts mass, on the other hand, did not change. He still contained the same amount of matter on the moon as he did on Earth. If the astronaut weighed 175 pounds on Earth, he would have weighed only 29 pounds on the moon. If his mass on Earth was 80 kg, what would his mass have been on the moon? [Figure 3]

Question: "When does the force of gravity change"

Answer: "When we change planets"

Question:
Energy often changes from one form to another. For example, the drummer transfers motion to sound energy. When the moving drumstick strikes the drum head, the drum starts to vibrate. The motion of the vibrating drum head creates the sound you hear. Any form of energy can change into any other form. Frequently, one form of energy changes into two or more different forms. Have you ever sat in front of a campfire? What are two things you notice? The fire creates light. It is also warm by the fire, meaning it creates heat. The energy of the fire comes from the stored energy in the wood. The wood contains chemical energy. As it burns, the chemical energy is changed into light and heat. Not all chemical energy changes produce light and heat. Our cars use gasoline as a fuel. Gasoline contains chemical energy. When our cars burn gasoline in their engines, it is converted into motion and heat. When energy changes forms, energy is conserved. After reading the above, is "Sound" the correct answer to the question "What is the stored energy in wood be turned into when burned in a campfire?"? OPTIONS:
- no
- yes

Answer:
no

Input: Bin Laden reportedly discussed the planes operation with KSM and Atef in a series of meetings in the spring of 1999 at the al Matar complex near Kandahar. KSM's original concept of using one of the hijacked planes to make a media statement was scrapped, but Bin Laden considered the basic idea feasible. Bin Laden, Atef, and KSM developed an initial list of targets. These included the White House, the U.S. Capitol, the Pentagon, and the World Trade Center. According to KSM, Bin Laden wanted to destroy the White House and the Pentagon, KSM wanted to strike the World Trade Center, and all of them wanted to hit the Capitol. No one else was involved in the initial selection of targets. Bin Laden also soon selected four individuals to serve as suicide operatives: Khalid al Mihdhar, Nawaf al Hazmi, Khallad, and Abu Bara al Yemeni. During the al Matar meetings, Bin Laden told KSM that Mihdhar and Hazmi were so eager to participate in an operation against the United States that they had already obtained U.S. visas. KSM states that they had done so on their own after the suicide of their friend Azzam (Nashiri's cousin) in carrying out the Nairobi bombing. KSM had not met them. His only guidance from Bin Laden was that the two should eventually go to the United States for pilot training. Hazmi and Mihdhar were Saudi nationals, born in Mecca. Like the others in this initial group of selectees, they were already experienced mujahideen. They had traveled together to fight in Bosnia in a group that journeyed to the Balkans in 1995. By the time Hazmi and Mihdhar were assigned to the planes operation in early 1999, they had visited Afghanistan on several occasions. Khallad was another veteran mujahid, like much of his family. His father had been expelled from Yemen because of his extremist views. Khallad had grown up in Saudi Arabia, where his father knew Bin Laden, Abdullah Azzam, and Omar Abdel Rahman (the "Blind Sheikh").
"What were the targets of 9/11, and who decided them?" is "Bosnia"?

Input: Greta ran to the corner with her older brother Tony. He had money for the ice cream truck in his pocket and she was very happy. The ice cream truck had been parked at the curb waiting for children for a very long time. The ice cream truck driver thought that no more children were coming to get ice cream so he started pulling away from the curb when they got to the corner. They yelled. They screamed, "Stop! Stop!" and jumped up and down on the side walk trying to get him to see them. The driver of the truck saw them, waved at them and smiled, pulled back to the curb and opened his truck up so that they could see everything that he had for sale. They were so excited. They saw some new treats. Tony wanted to try something new. He got an ice cream sundae with chocolate ice cream and nuts. He almost got a snow cone. Greta looked at everything that the ice cream truck had. She saw candy, ice cream cones, snow cones, and everything else. It all looked so good. But after looking at everything, she wanted to get an ice cream sandwich. She got the ice cream sandwich. She bit into it and smiled. It tasted so good. She felt so happy. Her brother, Tony, was happy too. He bit into his ice cream cone sundae and grinned. They walked home with their ice cream and told their mom about how close they came to not getting their ice cream at all. Their mom was happy that the truck had stopped for them. She said that they were very lucky to have gotten to the curb before the ice cream truck left.
"What did Greta end up getting from the ice cream truck after looking at everything?" is "She got an ice cream sandwich after looking at all of the options"?

OPTIONS:
- no
