input with options: Answer the following question given this paragraph: Gravity has traditionally been defined as a force of attraction between things that have mass. According to this conception of gravity, anything that has mass, no matter how small, exerts gravity on other matter. Gravity can act between objects that are not even touching. In fact, gravity can act over very long distances. However, the farther two objects are from each other, the weaker is the force of gravity between them. Less massive objects also have less gravity than more massive objects. Q: What is the term for the force of attraction between things that have a mass? A:
OPTIONS:
- weight
- motion
- magnetism
- gravity
output: gravity

input with options: Answer the following question given this paragraph: Just as the burning of wood releases energy in the form of heat, many other chemical reactions also release heat. There are also chemical reactions, such as photosynthesis in plants, which absorb energy in the form of heat. The study of energy changes in chemical reactions is called thermochemistry . The broader term thermodynamics also looks at how heat, work, and various forms of energy are related to one another. In this lesson, we will study the difference between reactions that absorb versus release heat as well as how to measure this change in energy. Q: What branch of physical science looks at how heat, work, and various forms of energy are related to one another? A:
OPTIONS:
- photosynthesis
- frigidity
- transformations
- thermodynamics
output: thermodynamics

input with options: Answer the following question given this paragraph: In the forward reaction, hydrogen and iodine combine to form hydrogen iodide. In the reverse reaction, hydrogen iodide decomposes back into hydrogen and iodine. The two reactions can be combined into one equation by the use of a double arrow. Q: In the forward reaction, hydrogen and iodine combine to form what? A:
OPTIONS:
- hydrogen ionicide
- ionic hydrogen
- iodinic hydrogen
- hydrogen iodide
output: hydrogen iodide

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
