Answer the following question given this paragraph: The four-chambered mammalian heart can pump blood in two different directions. The right side of the heart pumps blood to the lungs to pick up oxygen. The left side of the heart pumps blood containing oxygen to the rest of the body. Because of the dual pumping action of the heart, all of the blood going to body cells is rich in oxygen. Q: How many chambers does a mammalian heart have? A:
OPTIONS:
- one
- five
- three

four

Answer the following question given this paragraph: Global winds occur in belts around the globe. They are caused by unequal heating of Earth's surface. The Coriolis effect causes global winds to blow on a diagonal over the surface. Unequal heating also causes jet streams high in the troposphere. Q: What effect causes global winds to blow on a diagonal over the earth's surface? A:
OPTIONS:
- dopler effect
- resonant effect
- centrifugal effect
- coriolis effect

Answer: coriolis effect

Answer: greenhouse

input with options: Answer the following question given this paragraph: Scientists measure the gases that escape from a volcano to predict eruptions. Gases like sulfur dioxide (SO 2 ), carbon dioxide (CO 2 ), hydrochloric acid (HCl), and water vapor can be measured at the site. Gases may also be measured from satellites. The amounts of gases and the ratios of gases are calculated to help predict eruptions. Q: Scientists measure the gases that escape from a volcano to predict what? A:
OPTIONS:
- storms
- floods
- snowfall
- eruptions
output: eruptions
