input with options: Answer the following question given this paragraph: Pectin, a carbohydrate from fruit juices, is a gel-forming substance important in jelly making. Silica gel, a colloidal dispersion of hydrated silicon dioxide, is formed when dilute hydrochloric acid is added to a dilute solution of sodium silicate. Canned Heat is a gel made by mixing alcohol and a saturated aqueous solution of calcium acetate. Q: What carbohydrate from fruit juices is a gel-forming substance important in jelly making? A:
OPTIONS:
- potassium
- gelatin
- cellulose
- pectin
output: pectin

Q: Answer the following question given this paragraph: You can follow the operation of an electricity-generating fission reactor in the image above. The reactor core is submerged in a pool of water. The heat from the fission reaction heats the water, which is pumped into a heat exchange container. There the heated water boils the water in the heat exchanger. The produced steam is forced through a turbine that spins a generator and produces electricity. After the water passes through the turbine, it is condensed back to liquid water and pumped back to the heat exchanger. Q: A turbine that spins a generator will produce? A:

OPTIONS:
- solar energy
- light
- magnetic fields
- electricity

A: electricity

input: OPTIONS:
- variation
- generation
- extinction
- evolution Now, answer this question: Answer the following question given this paragraph: Evolution occurs in a population when its allele frequencies change over time. For example, the frequency of the A allele might change from 0.7 to 0.8. If that happens, evolution has occurred. What causes allele frequencies to change? The answer is forces of evolution. Q: What occurs in a population when its allele frequencies change over time? A:
A:
output: evolution

Answer the following question given this paragraph: Primary Producers/Food Sources Protists are essential sources of nutrition for many other organisms. In some cases, as in plankton, protists are consumed directly. Alternatively, photosynthetic protists serve as producers of nutrition for other organisms. For instance, photosynthetic dinoflagellates called zooxanthellae use sunlight to fix inorganic carbon. In this symbiotic relationship, these protists provide nutrients for coral polyps (Figure 23.29) that house them, giving corals a boost of energy to secrete a calcium carbonate skeleton. In turn, the corals provide the protist with a protected environment and the compounds needed for photosynthesis. This type of symbiotic relationship is important in nutrient-poor environments. Without dinoflagellate symbionts, corals lose algal pigments in a process called coral bleaching, and they eventually die. This explains why reefbuilding corals do not reside in waters deeper than 20 meters: insufficient light reaches those depths for dinoflagellates to photosynthesize. Q: Without dinoflagellate symbionts, corals lose algal pigments in a process called coral bleaching and eventually die, while corals in turn provide protection, making this what type of relationship?. A:

OPTIONS:
- idealistic
- semantic
- parasitic
- symbiotic

Answer: symbiotic

Problem: OPTIONS:
- water vapor
- freon
- calcium
- hydrogen
Q: Answer the following question given this paragraph: the fact that stars are made up of very lightweight hydrogen gas. Q: What type of gas are stars made up of? A:
Answer: hydrogen

Answer the following question given this paragraph: Over much of Earth's past, the climate was warmer than it is today. Picture in your mind dinosaurs roaming the land. They're probably doing it in a pretty warm climate! But ice ages also occurred many times in the past. An ice age is a period when temperatures are cooler than normal. This causes glaciers to spread to lower latitudes. Scientists think that ice ages occurred at least six times over the last billion years alone. How do scientists learn about Earth's past climates?. Q: What do you call a period when temperatures are cooler than normal, causing glaciers to spread? A:

OPTIONS:
- polar age
- earth age
- thermal age
- ice age

Answer:
ice age
