Question: Answer the following question given this paragraph: and procaine. Not only do catalysts greatly increase the rates of reactions, but in some cases such as in petroleum refining, they also control which products are formed. The acceleration of a reaction by a catalyst is called catalysis. Q: Catalysts can greatly increase the rates of chemical what? A:
OPTIONS:
- photosynthesis
- decay
- effects
- reactions
Answer: reactions

input with options: Answer the following question given this paragraph: Superposition refers to the position of rock layers and their relative ages ( Figure below ). Relative age means age in comparison with other rocks, either younger or older. The relative ages of rocks are important for understanding Earth's history. New rock layers are always deposited on top of existing rock layers. Therefore, deeper layers must be older than layers closer to the surface. This is the law of superposition. Q: Deeper layers of rock must be older than layers closer to the surface, this is the law of what? A:
OPTIONS:
- erosion
- diffraction
- flux
- superposition
output: superposition

Q: Answer the following question given this paragraph: Figure 3.20 The phospholipid bilayer is the major component of all cellular membranes. The hydrophilic head groups of the phospholipids face the aqueous solution. The hydrophobic tails are sequestered in the middle of the bilayer. Q: The major component of what cellular structures is the phospholipid bilayer? A:

OPTIONS:
- cytoplasm
- nuclei
- ribosomes
- cell membranes

A: cell membranes

input: OPTIONS:
- waterproofness
- webbed feet
- bonelessness
- flightlessness Now, answer this question: Answer the following question given this paragraph: There are about 10,000 living species of birds. Almost all of them can fly. Flying birds are classified in 29 orders. Most species belong to the order of perching birds. A few birds are flightless, such as the ostrich and penguin, but they evolved from a flying ancestor. Q: What important and unusual physical property (for birds) do ostriches and penguins share? A:
A:
output: flightlessness

Answer the following question given this paragraph: Hookworms, such as Ancyclostoma and Necator, infest the intestines and feed on the blood of mammals, especially in dogs, cats, and humans. Trichina worms (Trichinella) are the causal organism of trichinosis in humans, often resulting from the consumption of undercooked pork; Trichinella can infect other mammalian hosts as well. Ascaris, a large intestinal roundworm, steals nutrition from its human host and may create physical blockage of the intestines. The filarial worms, such as Dirofilaria and Wuchereria, are commonly vectored by mosquitoes, which pass the infective agents among mammals through their blood-sucking activity. Dirofilaria immitis, a blood-infective parasite, is the notorious dog heartworm species. Wuchereria bancrofti infects the lymph nodes of humans, resulting in the non-lethal but deforming condition called elephantiasis, in which parts of the body become swelled to gigantic proportions due to obstruction of lymphatic drainage and inflammation of lymphatic tissues. Q: What part of the body do hookworms infest? A:

OPTIONS:
- lungs
- skin
- brain
- intestines

Answer: intestines

Q: Answer the following question given this paragraph: Sometime in your life you've asked a question about the world around you. Probably you've asked a lot of questions over the years. The best way to answer questions about the natural world is by using science. Scientists ask questions every day, and then use a set of steps to answer those questions. The steps are known as the scientific method. By following the scientific method, scientists come up with the best information about the natural world. As a scientist, you need to do experiments to find out about the world. You also need to wonder, observe, talk, and think. Everything we learn helps us to ask new and better questions. Q: What is the set of steps that scientists use to learn about the world? A:

OPTIONS:
- philosophic method
- rhythm method
- Socratic method
- scientific method

A:
scientific method
