Question: Answer the following question given this paragraph: When we run a reaction to produce a gas, we expect it to rise into the air. Many students have done experiments where gases such as hydrogen are formed. The gas can be trapped in a test tube held upside-down over the reaction. Carbon dioxide, on the other hand, sinks when it is released. Carbon dioxide has a density greater that air, so it will not rise like these other gases would. Q: Carbon dioxide does not rise like other gases because it has a density greater than what? A:
OPTIONS:
- gravity
- light
- water
- air
Answer: air

input with options: Answer the following question given this paragraph: Some solids are not crystals. Glass, or the rock obsidian, are solid. However, they are not crystals. In a crystal , the atoms are arranged in a pattern. This pattern is regular and it repeats. The image below shows how the atoms are arranged in halite (table salt) ( Figure below ). Halite contains atoms of sodium and chlorine in a pattern. Notice that the pattern goes in all three dimensions. Q: What type of solid has atoms arranged in a repeating pattern? A:
OPTIONS:
- ions
- metals
- hydrocarbons
- crystals
output: crystals

Q: Answer the following question given this paragraph: Cooling or evaporation of fresh water from the sea surface makes surface water dense. This causes the surface water to undergo downwelling. Q: Cooling or evaporation of what from the sea surface makes surface water dense? A:

OPTIONS:

- salt water
- warm water
- fresh water

A: fresh water

input: OPTIONS:
- particle

It strikes everything on Earth's surface, including these volleyball players. Q: What type of radiation from the sun reaches earth across space striking everything on earth's surface? A:
A:
output: electromagnetic

Answer the following question given this paragraph: Figure 42.18 Vaccines are often delivered by injection into the arm. (credit: U. Navy Photographer's Mate Airman Apprentice Christopher D. Blachly). Q: What preventative measure is often delivered by injection into the arm? A:

OPTIONS:
- medication
- anesthesia

Answer: vaccine

Q: Answer the following question given this paragraph: This animation (http://openstaxcollege. org/l/insulin) describe the role of insulin and the pancreas in diabetes. Impaired insulin function can lead to a condition called diabetes mellitus, the main symptoms of which are illustrated in Figure 37.10. This can be caused by low levels of insulin production by the beta cells of the pancreas, or by reduced sensitivity of tissue cells to insulin. This prevents glucose from being absorbed by cells, causing high levels of blood glucose, or hyperglycemia (high sugar). High blood glucose levels make it difficult for the kidneys to recover all the glucose from nascent urine, resulting in glucose being lost in urine. High glucose levels also result in less water being reabsorbed by the kidneys, causing high amounts of urine to be produced; this may result in dehydration. Over time, high blood glucose levels can cause nerve damage to the eyes and peripheral body tissues, as well as damage to the kidneys and cardiovascular system. Oversecretion of insulin can cause hypoglycemia, low blood glucose levels. This causes insufficient glucose availability to cells, often leading to muscle weakness, and can sometimes cause unconsciousness or death if left untreated. Q: Oversecretion of insulin can cause what? A:

OPTIONS:
- hyperglycemia
- inflammation
- hypoxia
- hypoglycemia

A:
hypoglycemia
