Problem: OPTIONS:
- condensation
- solidification
- vaporization
- sublimation
Q: Answer the following question given this paragraph: The process in which a solid changes directly to a gas is called sublimation . It occurs when the particles of a solid absorb enough energy to completely overcome the force of attraction between them. Dry ice (solid carbon dioxide, CO 2 ) is an example of a solid that undergoes sublimation. Figure below shows a chunk of dry ice changing directly to carbon dioxide gas. Sometimes snow undergoes sublimation as well. This is most likely to occur on sunny winter days when the air is very dry. What gas does snow become?. Q: What is the process in which a solid changes directly to a gas called? A:
Answer: sublimation

Problem:OPTIONS:
- weathering
- flooding
- wind erosion
- soil erosion

Answer the following question given this paragraph: Many human actions make it easier for wind and water to carry away soil. They include plowing, logging, construction, and even some types of recreation. Q: Human actions such as plowing, logging, construction and other actions contribute to what kind of erosion? A:
****
A: soil erosion

Answer the following question given this paragraph: The seedless vascular plants include club mosses, which are the most primitive; whisk ferns, which lost leaves and roots by reductive evolution; and horsetails and ferns. Ferns are the most advanced group of seedless vascular plants. They are distinguished by large leaves called fronds and small sporangia-containing structures called sori, which are found on the underside of the fronds. Mosses play an essential role in the balance of the ecosystems; they are pioneering species that colonize bare or devastated environments and make it possible for a succession to occur. They contribute to the enrichment of the soil and provide shelter and nutrients for animals in hostile environments. Mosses and ferns can be used as fuels and serve culinary, medical, and decorative purposes. Q: What are the most advanced group of seedless vascular plants called? A:
OPTIONS:
- shrubs
- conifers
- grasses
- ferns
ferns

Answer the following question given this paragraph: Diamond is a form of carbon in which each carbon atom is covalently bonded to four other carbon atoms. This forms a strong, rigid, three-dimensional structure (see Figure below ). Diamond is the hardest natural substance, and no other natural substance can scratch it. This property makes diamonds useful for cutting and grinding tools as well as for rings and other jewelry (see Figure below ). Q: The hardest natural substance, diamond is a form of what element? A:
OPTIONS:
- zirconium
- zenon
- hydrogen
- carbon

Answer: carbon

Question: Answer the following question given this paragraph: Mercury is very close to the Sun, so it can get very hot. Mercury also has virtually no atmosphere. As the planet rotates very slowly, the temperature varies tremendously. In direct sunlight, the surface can be as hot as 427C (801F). On the dark side, the surface can be as cold as 183C (297F)! The coldest temperatures may be on the insides of craters. Most of Mercury is extremely dry. Scientists think that there may be a small amount of water, in the form of ice, at the planet's poles. The poles never receive direct sunlight. Q: What planet is closest to our sun? A:
OPTIONS:
- Earth
- Venus
- Pluto
- mercury
Answer: mercury

input: OPTIONS:
- a carbohydrate
- a fat

There are 20 different amino acids commonly found in the proteins of living things. Small proteins may contain just a few hundred amino acids, whereas large proteins may contain thousands of amino acids. Q: What is an organic compound made up of small molecules called amino acids called? A:
