Answer the following question given this paragraph: Chemical sedimentary rocks form when crystals precipitate out from a liquid. The mineral halite, also called rock salt, forms this way. You can make halite! Leave a shallow dish of salt water out in the Sun. As the water evaporates, salt crystals form in the dish. There are other chemical sedimentary rocks, like gypsum ( Figure below ). Q: What are formed when crystals precipitate out from a liquid? A:

OPTIONS:
- diamonds
- additive sedimentary rocks
- gaseous sedimentary rocks
- chemical sedimentary rocks

Answer: chemical sedimentary rocks

Problem: OPTIONS:
- lungs
- layers
- pores
- gills
Q: Answer the following question given this paragraph: Fish have gills that allow them to "breathe" oxygen in water. Water enters the mouth, passes over the gills, and exits the body through a special opening. Gills absorb oxygen from the water as it passes over them. Q: What do fish have that allow them to "breathe" oxygen in water? A:
Answer: gills

Problem:OPTIONS:
- gathering materials
- making a conclusion
- independent variables
- testing the hypothesis

Answer the following question given this paragraph: Scientific method is a process consisting of making observations, developing a hypothesis, and testing that hypothesis. Q: What takes place directly after developing a hypothesis in the scientific method process? A:
****
A: testing the hypothesis

Answer the following question given this paragraph: Radiotherapy is effective against cancer because cancer cells reproduce rapidly and, consequently, are more sensitive to radiation. The central problem in radiotherapy is to make the dose for cancer cells as high as possible while limiting the dose for normal cells. The ratio of abnormal cells killed to normal cells killed is called the therapeutic ratio, and all radiotherapy techniques are designed to enhance this ratio. Radiation can be concentrated in cancerous tissue by a number of techniques. One of the most prevalent techniques for well-defined tumors is a geometric technique shown in Figure 32.13. A narrow beam of radiation is passed through the patient from a variety of directions with a common crossing point in the tumor. This concentrates the dose in the tumor while spreading it out over a large volume of normal tissue. The external radiation can be x-rays, 60 Co rays, or ionizing-particle beams produced by accelerators. Accelerator-produced beams of neutrons, -mesons , and heavy ions such as nitrogen nuclei have been employed, and these can be quite effective. These particles have larger QFs or RBEs and sometimes can be better localized, producing a greater therapeutic ratio. But accelerator radiotherapy is much more expensive and less frequently employed than other forms. Q: Radiotherapy is effective against cancer because cancer cells reproduce rapidly and, consequently, are more sensitive to this? A:
OPTIONS:
- UV light
- separation
- destruction
- radiation
radiation

Answer the following question given this paragraph: Bacterial infections of urinary organs, especially the urinary bladder, are common. They are called urinary tract infections. Generally, they can be cured with antibiotic drugs. However, if they aren't treated, they can lead to more serious infections and damage to the kidneys. Q: Antibiotic drugs are usually effective in treating what kind of infections? A:
OPTIONS:
- viral
- lethal
- biological
- bacterial

Answer: bacterial

input with options: Answer the following question given this paragraph: Ice is an example of solid matter. A solid is matter that has a fixed volume and a fixed shape. Figure below shows examples of matter that are usually solids under Earth conditions. In the figure, salt and cellulose are examples of crystalline solids. The particles of crystalline solids are arranged in a regular repeating pattern. The steaks and candle wax are examples of amorphous ("shapeless") solids. Their particles have no definite pattern. Q: What is the name for a matter that has a fixed volume and a fixed shape? A:
OPTIONS:
- gas
- stable
- liquid
- solid
output:
solid
