Answer the following question given this paragraph: These devices are not very sensitive to low levels of radiation, but more sensitive devices are also available that reliably measure the frequency of radioactive events. One such device is the Geiger counter. A Geiger counter is a tube filled with an inert gas that will conduct electricity when exposed to charged radiation, such as alpha or beta particles. When a charged particle enters the tube, it changes the electrical potential between the anode and the cathode, and this change in potential is registered by an electrical circuit as a single radioactive event. Geiger counters are fairly inexpensive and reliable, so they are useful in a wide range of applications. More complicated types of counters are also available, but are generally used only in sophisticated experiments. Q: What is the tube-like device used to reliably measure lower levels of radiation? A:

OPTIONS:
- Richter scale
- weber counter
- MRI machine
- geiger counter

Answer: geiger counter

Problem: OPTIONS:
- thermal potential
- specific gravity
- momentum
- specific heat
Q: Answer the following question given this paragraph: where the mass, specific heat, and change in temperature are multiplied together. Specific heat is a measure of how much energy is needed to change the temperature of a substance; the larger the specific heat, the more energy is needed to change the temperature. The units for specific heat are depending on what the unit of Tis. You may note a departure from the insistence that temperature be expressed in Kelvin. That is because a change in temperature has the same value whether the temperatures are expressed in degrees Celsius or kelvins. Q: What is a measure of how much energy is needed to change the temperature of a substance? A:
Answer: specific heat

Problem:OPTIONS:
- nitric acid
- residual acid
- excessive acid
- lactic acid

Answer the following question given this paragraph: Animals and some bacteria and fungi carry out lactic acid fermentation. Lactic acid is a waste product of this process. Our muscles perform lactic acid fermentation during strenuous exercise, since oxygen cannot be delivered to the muscles quickly enough. The buildup of lactic acid is believed to make your muscles sore after exercise. Bacteria that produce lactic acid are used to make cheese and yogurt. The lactic acid causes the proteins in milk to thicken. Lactic acid also causes tooth decay, because bacteria use the sugars in your mouth for energy. Q: During strenuous exercise our muscles perform what kind of fermentation? A:
****
A: lactic acid

Answer the following question given this paragraph: Refraction is another way that waves interact with matter. Refraction occurs when waves bend as they enter a new medium at an angle. You can see an example of refraction in Figure below . Light bends when it passes from air to water. The bending of the light causes the pencil to appear broken. Q: Light bends when it passes in from what to what? A:
OPTIONS:
- air to ground
- product to water
- water to air
- air to water
air to water

Answer the following question given this paragraph: Q: The cells of what basic plant structure lack chloroplasts? A:
OPTIONS:
- leaf
- stem
- ferns
- root

Answer: root

input with options: Answer the following question given this paragraph: One type of molecular compound behaves quite differently than that described so far. A covalent network solid is a compound in which all of the atoms are connected to one another by covalent bonds. Diamond is composed entirely of carbon atoms, each bonded to four other carbon atoms in a tetrahedral geometry. Melting a covalent network solid is not accomplished by overcoming the relatively weak intermolecular forces. Rather, all of the covalent bonds must be broken, a process that requires extremely high temperatures. Diamond, in fact, does not melt at all. Instead, it vaporizes to a gas at temperatures above 3500C. Q: What is a compound in which all of the atoms are connected to one another by covalent bonds? A:
OPTIONS:
- covalent bond element
- covalent mixture
- compound metal
- covalent network solid
output:
covalent network solid
