input: OPTIONS:
- rivers
- continents
- mountains
- oceans Now, answer this question: Answer the following question given this paragraph: Oceans cover more than 70 percent of Earth's surface and hold 97 percent of its surface water. It's no surprise that the oceans have a big influence on the planet. The oceans affect the atmosphere, climate, and living things. Q: The earth's atmosphere, climate, and living things are effected by what feature that covers more than 70 percent of earth's surface? A:
A:
output: oceans

Answer the following question given this paragraph: A metal is an element that is a good conductor of heat and electricity. Metals are also malleable, which means that they can be hammered into very thin sheets without breaking, and ductile, which means that they can be drawn into wires. When a fresh surface of any metal is exposed, it will be very shiny, because it reflects light well. This property is referred to as luster. All metals are solid at room temperature except mercury (Hg), which is a liquid. The melting points of different metals vary widely. Mercury has the lowest melting point of all pure metals (39C), and tungsten (W) has the highest (3422C). On the periodic table in Figure above , the metals are shaded blue and are located to the left of the bold stair-step line. About 80 percent of the elements are metals (see examples in Figure below ). Q: Which metal is not a solid even at room temperature? A:

OPTIONS:
- iron
- copper
- aluminum
- mercury

Answer: mercury

Problem: OPTIONS:
- stomach
- kidney
- gallbladder
- thyroid
Q: Answer the following question given this paragraph: The molecule pictured above is thyroxine, a compound produced by the thyroid gland. This molecule regulates how the body uses energy. In a condition known as hypothyroidism, the thyroid makes less thyroxine than normal. A person with this disease feels tired all the time and often puts on weight. Treatment with thyroid hormone supplements takes care of the problem. Q: The molecule pictured above is thyroxine, a compound produced by which gland? A:
Answer: thyroid

Problem:OPTIONS:
- variation
- abundance
- deatn
- reproduction

Answer the following question given this paragraph: 45.2 Life Histories and Natural Selection All species have evolved a pattern of living, called a life history strategy, in which they partition energy for growth, maintenance, and reproduction. These patterns evolve through natural selection; they allow species to adapt to their environment to obtain the resources they need to successfully reproduce. There is an inverse relationship between fecundity and parental care. A species may reproduce early in life to ensure surviving to a reproductive age or reproduce later in life to become larger and healthier and better able to give parental care. A species may reproduce once (semelparity) or many times (iteroparity) in its life. Q: All species have evolved a pattern of living, called a life history strategy, in which they partition energy for growth, maintenance, and what? A:
****
A: reproduction

Answer the following question given this paragraph: Dolphins are living organisms, so studying them is part of the life sciences. The life sciences, however, are broken down into many fields. Scientists that study dolphins and other life in the ocean are called marine biologists. Q: Scientists that study dolphins and other life in the ocean are called what? A:
OPTIONS:
- marine geneticists
- sea biologists
- ocean biologists
- marine biologists
marine biologists

Answer the following question given this paragraph: Many of the fibers that compose the materials for our clothes are naturally occurring. Silk and cotton are examples of natural fibers. Silk is produced by the silkworm, and cotton is grown as a plant. However, several chemical processes are used to treat silk thread so that it is shrink-resistant and will repel water. Chemical dyes are frequently used to color various fabrics. Cleaning requires special soaps or chemicals used to dry-clean materials. Cotton will grow better if the boll weevil (an insect that kills the plant) is eliminated with the use of specific insecticides. Ironing of cotton is made easier by the use of chemicals that produce a permanent press in the material. Q: Silk and cotton are examples of what type of fibers? A:
OPTIONS:
- mechanical
- artificial
- coral
- natural

Answer:
natural
