Question: Answer the following question given this paragraph: If plaque blocks coronary arteries that supply blood to the heart, coronary heart disease results. Poor blood flow to the heart may cause chest pain or a heart attack. A heart attack occurs when the blood supply to part of the heart muscle is completely blocked so that cardiac muscle cells die. Coronary heart disease is the leading cause of death in U. S adults. Q: Coronary heart disease is caused when what blocks coronary arteries? A:
OPTIONS:
- proteins
- carbohydrates
- fats
- plaque
Answer: plaque

input with options: Answer the following question given this paragraph: a small scrap of paper onto a droplet of water, the paper floats on top of the water droplet, although the object is denser (heavier) than the water. This occurs because of the surface tension that is created by the water molecules. Cohesion and surface tension keep the water molecules intact and the item floating on the top. It is even possible to "float" a steel needle on top of a glass of water if you place it gently, without breaking the surface tension (Figure 2.11). Q: What causes a small scrap of paper placed on top of the water droplet to float , although the object is denser (heavier) than the water? A:
OPTIONS:
- diffusion
- transfusion
- van der waals force
- surface tension
output: surface tension

Q: Answer the following question given this paragraph: Besides the four parts listed above, many cells also have a nucleus. The nucleus of a cell is a structure enclosed by a membrane that contains most of the cell's DNA. Cells are classified in two major groups based on whether or not they have a nucleus. The two groups are prokaryotic cells and eukaryotic cells. Q: What structure of a cell is enclosed by a membrane and contains most of the cell's dna? A:

OPTIONS:
- vacuole
- ribosome
- epidermis
- nucleus

A: nucleus

input: OPTIONS:
- resonant effect
- volumetric effect
- tonal effect
- coriolis effect Now, answer this question: Answer the following question given this paragraph: Zappy's. Flight paths look curved due to the Coriolis effect . CC BY-NC 3.0. Q: What effect is responsible for flight paths looking curved? A:
A:

Answer the following question given this paragraph: A: Acid rain dissolves and damages stone buildings and statues. The Figure below shows a statue that has been damaged by acid rain. Q: What type of rain dissolves and damages stone buildings and statues? A:

OPTIONS:
- plastic rain
- morning rain
- stored rain
- acid rain

Answer: acid rain

Q: Answer the following question given this paragraph: Streams often start in mountains, where the land is very steep. You can see an example in Figure below . A mountain stream flows very quickly because of the steep slope. This causes a lot of erosion and very little deposition. The rapidly falling water digs down into the stream bed and makes it deeper. It carves a narrow, V-shaped channel. Q: Where do streams often start? A:

OPTIONS:
- valleys
- oceans
- plains
- mountains

A:
mountains
