Problem: OPTIONS:
- spreading friction
- static friction
- rolling friction
- sliding friction
Q: Answer the following question given this paragraph: Sliding friction is friction that acts on objects when they are sliding over a surface. Sliding friction is weaker than static friction. That's why it's easier to slide a piece of furniture over the floor after you start it moving than it is to get it moving in the first place. Sliding friction can be useful. For example, you use sliding friction when you write with a pencil. The pencil "lead" slides easily over the paper, but there's just enough friction between the pencil and paper to leave a mark. Q: What type of friction is friction that acts on objects when they are sliding over a surface? A:
Answer: sliding friction

Problem:OPTIONS:
- latitude
- longitude
- plate
- equator

Answer the following question given this paragraph: Q: What is the name for the line dividing the earth's hemispheres? A:
****
A: equator

Answer the following question given this paragraph: For example, in the fall, when the days start to get shorter, the trees sense that there is less sunlight. The plant is stimulated, and it sends messages telling the leaves to change colors and fall. This is an example of photoperiodism , the reaction of organisms, such as plants, to the length of day or night. Photoperiodism is also the reaction of plants to the length of light and dark periods. Many flowering plants sense the length of night, a dark period, as a signal to flower. Each plant has a different photoperiod, or night length. When the plant senses the appropriate length of darkness, resulting in an appropriate length of daylight, it flowers. Flowering plants are classified as long-day plants or short-day plants. Long-day plants flower when the length of daylight exceeds the necessary photoperiod, and short-day plants flower when the day length is shorter than the necessary photoperiod. Long-day plants include carnations, clover, lettuce, wheat, and turnips. Short-day plants include cotton, rice, and sugar cane. Q: What happens to the length of the days in the fall? A:
OPTIONS:
- they stay the same
- they change randomly
- they get longer
- they get shorter
they get shorter

Answer the following question given this paragraph: 23.4 The Stomach The stomach participates in all digestive activities except ingestion and defecation. It vigorously churns food. It secretes gastric juices that break down food and absorbs certain drugs, including aspirin and some alcohol. The stomach begins the digestion of protein and continues the digestion of carbohydrates and fats. It stores food as an acidic liquid called chyme, and releases it gradually into the small intestine through the pyloric sphincter. Q: What organ participates in all digestive activities except ingestion and defecation? A:
OPTIONS:
- small intestine
- tongue
- large intestine
- stomach

Answer: stomach

Question: Answer the following question given this paragraph: Small streams often flow into bigger streams or rivers. The small streams are called tributaries. A river and all its tributaries make up a river system. Q: What do a river and all its tributaries make up? A:
OPTIONS:
- abundance system
- water system
- food system
- river system
Answer: river system

input: OPTIONS:
- fatty microorganisms
- lentiviruses microorganisms
- sponges microorganisms
- chemosynthetic microorganisms Now, answer this question: Answer the following question given this paragraph: These brilliant red "feathers" are actually animals called tube worms. They live in an extreme environment on the deep ocean floor, thousands of meters below the water's surface. Their world is always very cold and completely dark. Without sunlight, photosynthesis is not possible. So what do organisms eat at these depths? Tube worms depend on chemosynthetic microorganisms that live inside them for food. In this and other ways, tube worms have adapted to the extreme conditions of their environment. Q: What do tube worms rely on for food? A:
A:
output:
chemosynthetic microorganisms
