Answer the following question given this paragraph: During a massive eruption all of the material may be ejected from a magma changer. Without support, the mountain above the empty chamber may collapse. This produces a huge caldera . Calderas are generally round, bowl-shaped formations like the picture in Figure below . Q: After a massive eruption what will a mountain collapsing above an empty chamber create? A:
****
A: caldera

Answer the following question given this paragraph: Fossils are a window into the past. They provide clear evidence that evolution has occurred. Scientists who find and study fossils are called paleontologists . How do they use fossils to understand the past? Consider the example of the horse, shown in Figure below . The fossil record shows how the horse evolved. Q: Scientists who find and study fossils are called what? A:
OPTIONS:
- biologists
- geologists
- anthropologist
- paleontologists
paleontologists

Answer the following question given this paragraph: Proteins are biochemical compounds that consist of one or more chains of small molecules called amino acids. Amino acids are the monomers of proteins. There are only about 20 different amino acids. The sequence of amino acids in chains and the number of chains in a protein determine the protein's shape. Shapes may be very complex. You can learn more about the shapes of proteins at this link:. Q: What is the name for biochemical compounds that consist of one or more chains of small molecules called amino acids? A:
OPTIONS:
- lipids
- protons
- hormones
- proteins

Answer: proteins

Question: Answer the following question given this paragraph: The global pattern of precipitation is influenced by movements of air masses.

OPTIONS:
- pollution masses
- air valleys
- clouds
- air masses
Answer: air masses

input with options: Answer the following question given this paragraph: No new mutations are occurring. Therefore, no new alleles are being created. Q: What is necessary for new alleles to be created? A:
OPTIONS:
- cross-pollination
- new rna
- new frequencies
- new mutations
output: new mutations

Problem: OPTIONS:
- multiplies

Q: Answer the following question given this paragraph: The pressure of the earth's atmosphere, as with any fluid, increases with the height of the column of air. In the case of earth's atmosphere, there are some complications. The density of the air is not uniform but decreases with altitude. Additionally there is no distinct top surface from which height can be measured. We can, however, calculate the approximate difference in pressure between two altitudes using the equation . The average pressure of the atmosphere at sea level is 1.013 10 5 Pa. This pressure is often expressed as 101.3 kPa. Q: What happens to the density of air as the altitude decreases? A:
Answer:
decreases
