input: OPTIONS:
- rocks
- the Sun
- caves
- oceans Now, answer this question: Answer the following question given this paragraph: Life probably began in the oceans. No one knows exactly how or when. Life may have originated more than once. If life began before the Moon formed, that impact would have wiped it out. Then life would have had to originate again. Eventually conditions on Earth became less violent. The planet could support life. Q: Life probably began where? A:
A:
output: oceans

Answer the following question given this paragraph: Just like it sounds, a wheel and axle is composed of two connected cylinders of different diameters. Since the wheel has a larger radius (distance) than the axle, the axle will always have a larger force than the wheel. The ideal mechanical advantage of a wheel and axle is dependent on the ratio between the radii:. Q: The ratio between the radii of a wheel and axle determines what? A:

OPTIONS:
- fundamental mechanical advantage
- introduced mechanical advantage
- theoretical mechanical advantage
- ideal mechanical advantage

Answer: ideal mechanical advantage

Problem: OPTIONS:
- potential energy
- subsequent energy
- stellar energy
- electrical energy
Q: Answer the following question given this paragraph: Electrical energy is transmitted by moving electrons in an electric current. In order to travel, electric current needs matter. It cannot pass through empty space. However, matter resists the flow of electric current. That's because flowing electrons in current collide with particles of matter, which absorb their energy. Some types of matter offer more or less resistance to electric current than others. Q: What is transmitted by moving electrons in an electric current? A:
Answer: electrical energy

Problem:OPTIONS:
- inverted
- darker
- invisible
- blurry

Answer the following question given this paragraph: Farsightedness, or hyperopia, is the condition in which distant objects are seen clearly, but nearby objects are blurry. It occurs when the eyeball is shorter than normal. This causes images to be focused in back of the retina. Hyperopia can be corrected with convex lenses. The lenses focus images farther forward in the eye, so they are on the retina instead of behind it. Q: Farsightedness, or hyperopia, is the condition in which distant objects are seen clearly, but nearby objects are? A:
****
A: blurry

Answer the following question given this paragraph: Once again, a mutation is the change in the DNA or RNA sequence. In multicellular organisms, mutations can be subdivided into germline mutations and somatic mutations. Germline mutations occur in the DNA of sex cells, or gametes, and are therefore potentially very serious. These mutations can be passed to the next generation. If the zygote contains the mutation, every cell in the resulting organism will have that mutation. If the mutation results in a disease phenotype, the mutation causes what is called a hereditary disease. Somatic mutations , which occur in somatic, or body, cells, cannot be passed to the next generation (offspring). Mutations present in a somatic cell of an organism will be present (by DNA replication and mitosis) in all descendants of that cell. If the mutation is present in a gene that is not used in that cell type, the mutation may have no effect. On the other hand, the mutation may lead to a serious medical condition such as cancer. Q: In multicellular organisms, mutations can be subdivided into germline mutations and? A:
OPTIONS:
- elective mutations
- comparative mutations
- resultant mutations
- somatic mutations
somatic mutations

Answer the following question given this paragraph: The troposphere is the lowest layer of the atmosphere. All of the air you breathe is in the troposphere. All of Earth's weatherwind, rain, snow, heatis in the troposphere. The troposphere is the lowest and most important layer of the atmosphere!. Q: What is the lowest layer of the atmosphere? A:
OPTIONS:
- ionosphere
- chromosphere
- lithosphere
- troposphere

Answer:
troposphere
