Answer the following question given this paragraph: Catalytic converters are used on motor vehicles. They break down pollutants in exhaust to non-toxic compounds. For example, they change nitrogen oxides to harmless nitrogen and oxygen gases. Q: Catalytic converters used on motor vehicles break down pollutants in what, yielding non-toxic compounds? A:
OPTIONS:
- muffler
- intake
- oil
- exhaust

Answer: exhaust

Question: Answer the following question given this paragraph: Roundworms make up the phylum Nematoda. They have a pseudocoelom and hydrostatic skeleton. Their body is covered with tough cuticle. Free-living roundworms are found mainly in freshwater habitats. Parasitic roundworms have a variety of hosts, including humans. Q: What has a pseudocoelom and hydrostatic skeleton? A:
OPTIONS:
- vertebrates
- omnivores
- gymnosperms
- roundworms
Answer: roundworms

input with options: Answer the following question given this paragraph: The lungs of mammals are unique in having alveoli. These are tiny, sac-like structures. Each alveolus is surrounded by a network of very small blood vessels (see Figure below ). Because there are millions of alveoli in each lung, they greatly increase the surface area for gas exchange between the lungs and bloodstream. Human lungs, for example, contain about 300 million alveoli. They give the lungs a total surface area for gas exchange of up to 90 square meters (968 square feet). That's about as much surface area as one side of a volleyball court!. Q: What in mammalian lungs, increases the surface area for gas exchange? A:
OPTIONS:
- bronchi
- thorax
- bronchioles
- alveoli
output: alveoli

Q: Answer the following question given this paragraph: Glycogen is a branched polymer of glucose and serves as energy storage in animals. Q: What is a branded polymer that serves as energy storage in animal? A:

OPTIONS:
- triglyceride
- hydrocarbon
- pathogen
- glycogen

A: glycogen

input: OPTIONS:
- pollution insulators
- sunlight insulators
- warmth insulators
- thermal insulators Now, answer this question: Answer the following question given this paragraph: Particles of gases are farther apart and have fewer collisions, so they are not good at transferring thermal energy. Materials that are poor thermal conductors are called thermal insulators . Figure below shows several examples. Fluffy yellow insulation inside the roof of a home is full of air. The air prevents the transfer of thermal energy into the house on hot days and out of the house on cold days. A puffy down jacket keeps you warm in the winter for the same reason. Its feather filling holds trapped air that prevents energy transfer from your warm body to the cold air outside. Solids like plastic and wood are also good thermal insulators. That's why pot handles and cooking utensils are often made of these materials. Q: What are materials that are poor thermal conductors called? A:
A:
output: thermal insulators
