Question: Answer the following question given this paragraph: If an ore is deep below Earth's surface it may be too expensive to remove all the rock above it. These deposits are taken by underground mining. Underground mines can be very deep. The deepest gold mine in South Africa is more than 3,700 m deep (that is more than 2 miles)! There are various methods of underground mining. Underground mining is more expensive than surface mining. Tunnels must be blasted into the rock so that miners and equipment can get to the ore. Underground mining is dangerous work. Fresh air and lights must be brought in to the tunnels for the miners. The miners breathe in lots of particles and dust while they are underground. The ore is drilled, blasted, or cut away from the surrounding rock and taken out of the tunnels. Sometimes there are explosions as ore is being drilled or blasted. This can lead to a mine collapse. Miners may be hurt or killed in a mining accident. Q: In what type of mining must tunnels be blasted into the rock so that miners and equipment can get to the ore? A:
OPTIONS:
- open-pit mining
- strip mining
- gold mining
- underground mining
Answer: underground mining

input with options: Answer the following question given this paragraph: Plant Parasites and Pathogens The production of sufficient good-quality crops is essential to human existence. Plant diseases have ruined crops, bringing widespread famine. Many plant pathogens are fungi that cause tissue decay and eventual death of the host (Figure 24.25). In addition to destroying plant tissue directly, some plant pathogens spoil crops by producing potent toxins. Fungi are also responsible for food spoilage and the rotting of stored crops. For example, the fungus Claviceps purpurea causes ergot, a disease of cereal crops (especially of rye). Although the fungus reduces the yield of cereals, the effects of the ergot's alkaloid toxins on humans and animals are of much greater significance. In animals, the disease is referred to as ergotism. The most common signs and symptoms are convulsions, hallucination, gangrene, and loss of milk in cattle. The active ingredient of ergot is lysergic acid, which is a precursor of the drug LSD. Smuts, rusts, and powdery or downy mildew are other examples of common fungal pathogens that affect crops. Q: Which is the active ingredient of cereal crop disease, ergot? A:
OPTIONS:
- byblis acid
- amino acid
- pixelation acid
- lysergic acid
output: lysergic acid

Q: Answer the following question given this paragraph: In a chemical reaction, the quantity of each element does not change; there is the same amount of each element in the products as there was in the reactants. This is because matter is always conserved. The conservation of matter is reflected in a reaction's chemical equation. The same number of atoms of each element appears on each side of the arrow. For example, in the chemical equation above, there are four hydrogen atoms on each side of the arrow. Can you find all four of them on each side of this equation?. Q: Matter is always conserved in what type of reaction? A:

OPTIONS:
- developed reaction
- Quick reaction
- toxic reaction
- chemical reaction

A: chemical reaction

input: OPTIONS:
- close to themselves
- different from themselves
- far away from
- similar to themselves Now, answer this question: Answer the following question given this paragraph: Nonrandom Mating If individuals nonrandomly mate with their peers, the result can be a changing population. There are many reasons nonrandom mating occurs. One reason is simple mate choice; for example, female peahens may prefer peacocks with bigger, brighter tails. Traits that lead to more matings for an individual become selected for by natural selection. One common form of mate choice, called assortative mating, is an individual's preference to mate with partners who are phenotypically similar to themselves. Another cause of nonrandom mating is physical location. This is especially true in large populations spread over large geographic distances where not all individuals will have equal access to one another. Some might be miles apart through woods or over rough terrain, while others might live immediately nearby. Q: One common form of mate choice, called assortative mating, is an individual's preference to mate with partners who are what? A:
A:
output: similar to themselves

Answer the following question given this paragraph: ♦️ Many industrial processes for preparing compounds use "continuous-flow reactors," which are chemical reaction vessels in which the reactants are mixed and allowed to react as they flow along a tube. The products are removed at a certain distance from the starting point, when the reaction is nearly complete. The key operating parameters in a continuous-flow reactor are temperature, reactor volume, and reactant flow rate. As an industrial chemist, you think you have successfully modified a particular process to produce a higher product yield by substituting one reactant for another. The viscosity of the new reactant is, however, greater than that of the initial reactant. Q: Continuous-flow reactors are chemical reaction vessels in which the what are mixed and allowed to react as they flow along a tube? A:

OPTIONS:
- reactives
- generators
- propellants
- reactants

Answer: reactants

Q: Answer the following question given this paragraph: Q: What is the study of the vital statistics of populations and how they change over time? A:

OPTIONS:
- sociology
- ethnography
- anthropology
- demography

A:
demography
