Input: Rough surfaces create more friction than smooth surfaces. Thats why cars have tires. Its also why we use rubber mats in areas that might get wet. In your bathtub, you may even use No-Slip tape. No-slip is another way of saying the items has a lot of friction. In Figure 1.9, the blades of the skates are very smooth. Thats why you cant slide across ice with shoes. The soles of your shoes are much rougher than skates. The rougher surface of shoes causes more friction and slows you down. Heavier objects also have more friction. A heavy object presses down with more force. The surfaces are held together more tightly. This makes the surfaces harder to slide past each other. Did you ever try to push something heavy across the floor? Heavy objects are much harder to push than light objects.
"What is harder to do when surfaces are held together more tightly?" is "Slide past each other"?

OPTIONS:
- no
- yes
Output: yes

Input: The factory is highly automated and designed to shift flexibly to produce many different kinds of chips to suit demand. "The diversity is the big difference with this plant," said Richard Doherty, president of Envisioneering, a research firm. "It gives IBM the capability to make so many different kinds of custom chips, and the world is going to custom chips." The 140,000-square-foot plant is a testament to advanced manufacturing technology. The 300-millimeter silicon wafers -- about the size of a standard pizza -- are shuttled around the facility in enclosed plastic pods, which ride on overhead tracks. They drop down from wires automatically into machines, sheathed in stainless steel and glass, for each stage of processing and fabrication. Throughout the 500 processing steps, which typically last 20 days, the wafers are not touched by human hands. The circuits etched into the chips are less than one thousandth the width of a human hair. Human operators are there to monitor the systems, catch errors and fine-tune the production process for maximum efficiency. Because each of the hundreds of processing machines is self-enclosed, and essentially airtight, the uniforms operators wear are less constricting than in the previous generation of chip plants, which looked like space suits. The operators at the East Fishkill factory wear light nylon uniforms, light blue shoe coverings and translucent hair nets made of paper. They look more like workers in a bakery. Yes, said Richard Brilla, director of the new facility, "but the donuts are a lot more costly here." Each wafer, holding hundreds of chips, is worth $6,000 to $10,000 apiece, depending on what insulation, circuitry and materials are used.

Does the response "Wear light nylon uniforms, light blue shoe coverings and translucent hair nets made of paper" correctly answer the question "What is the brief summarization of the appearance of the operators' uniforms as described above?"?

Tim had always a red bike. His birthday party was coming up and he hoped that his parents would finally get him the bike. When his friends came over for the party, Tim was very worried that he wouldn't get the bike. He looked at all the presents and none of them seemed big enough to have a bike in them. Tim was sad. When it was time to open the presents he opened them one at a time. The first present was not a bike. The second present was not a bike. The third present was the biggest one. Tim knew if the bike was going to be in any of the presents it was going to be in this box. Tim opened it and there was no bike inside. Just as Tim tried not to look too upset, his Dad brought in the biggest present of them all. His Dad had been hiding the present all along. Tim opened it and his new bike was inside the box. Tim put the bike together with his Dad's help.

Question: "How many presents did Tim open before opening his bike?"

OPTIONS:
- no
- yes

Answer: "6"

Response: no

Problem: Living things need non-living matter as well as energy. What do you think matter is used for? One thing is to build bodies. They also need it to carry out the processes of life. Any non-living matter that living things need is called a nutrient. Carbon and nitrogen are examples of nutrients. Unlike energy, matter is recycled in ecosystems. You can see how in Figure 3.11. Decomposers release nutrients when they break down dead organisms. The nutrients are taken up by plants through their roots. The nutrients pass to primary consumers when they eat the plants. The nutrients pass to higher level consumers when they eat lower level consumers. When living things die, the cycle repeats.

Question: "What happens to nutrients when the decomposers use them to break down dead organisms?"

Answer: "Take up by plants"

OPTIONS:
- no
- yes
Answer:
yes
