input with options: Answer the following question given this paragraph: Fossils may form in other ways. With complete preservation, the organism doesn't change much. As seen below, tree sap may cover an organism and then turn into amber. The original organism is preserved so that scientists might be able to study its DNA. Organisms can also be completely preserved in tar or ice. Molds and casts are another way organisms can be fossilized. A mold is an imprint of an organism left in rock. The organism's remains break down completely. Rock that fills in the mold resembles the original remains. The fossil that forms in the mold is called a cast. Molds and casts usually form in sedimentary rock. With compression, an organism's remains are put under great pressure inside rock layers. This leaves behind a dark stain in the rock. Q: A mold is an imprint of an organism left in what? A:
OPTIONS:
- magma
- band
- fossil
- rock
output: rock

OPTIONS:
- helper blood cells
- blue blood cells
- red blood cells
- white blood cells

A: white blood cells

It is most frequent in adolescents and young adults, and is more common in females. It often results from excessive running, particularly downhill, but may also occur in athletes who do a lot of knee bending, such as jumpers, skiers, cyclists, weight lifters, and soccer players. It is felt as a dull, aching pain around the front of the knee and deep to the patella. The pain may be felt when walking or running, going up or down stairs, kneeling or squatting, or after sitting with the knee bent for an extended period. Patellofemoral syndrome may be initiated by a variety of causes, including individual variations in the shape and movement of the patella, a direct blow to the patella, or flat feet or improper shoes that cause excessive turning in or out of the feet or leg. These factors may cause in an imbalance in the muscle pull that acts on the patella, resulting in an abnormal tracking of the patella that allows it to deviate too far toward the lateral side of the patellar surface on the distal femur. Because the hips are wider than the knee region, the femur has a diagonal orientation within the thigh, in contrast to the vertically oriented tibia of the leg (Figure 8.17). The Q-angle is a measure of how far the femur is angled laterally away from vertical. The Q-angle is normally 1015 degrees, with females typically having a larger Q-angle due to their wider pelvis. During extension of the knee, the quadriceps femoris muscle pulls the patella both superiorly and laterally, with the lateral pull greater in women due to their large Q-angle. This makes women more vulnerable to developing patellofemoral syndrome than men. Normally, the large lip on the lateral side of the patellar surface of the femur compensates for the lateral pull on the patella, and thus helps to maintain its proper tracking. However, if the pull produced by the medial and lateral sides of the quadriceps femoris muscle is... Q: What body joint incurs the most common overuse injury among runners and other athletes? A:
A:
output: knee

Answer the following question given this paragraph: The elements mercury, gold, and copper display properties that are common of metals. Mercury ( left ) is the only metal that is a liquid at room temperature. Even in its liquid form, it still has a high luster. Gold ( middle ) is malleable and can be formed into very thin sheets called gold leaf. Because copper ( right ) is ductile, inexpensive, and a good conductor, it is used extensively in electrical wiring. Q: What is the only metal that is a liquid at room temperature? A:

OPTIONS:
- copper
- aluminum
- tin
- mercury

Answer: mercury

Problem: OPTIONS:
- prokaryotes
- plants
- arthropods
- protists
Q: Answer the following question given this paragraph: Scientists think that protists are the oldest eukaryotes. If so, they must have evolved from prokaryotic cells. How did this happen? The endosymbiotic theory provides the most widely-accepted explanation. That's because it is well supported by evidence. Q: What do many scientists think are the oldest eukaryotes? A:
Answer: protists

Answer the following question given this paragraph: Acids have some properties in common. They turn litmus, a plant extract, red. They react with some metals to give off H2 gas. They react with carbonate and hydrogen carbonate salts to give off CO2 gas. Acids that are ingested typically have a sour, sharp taste. (The name acid comes from the Latin word acidus, meaning "sour. ") Bases also have some properties in common. They are slippery to the touch, turn litmus blue, and have a bitter flavor if ingested. Acids and bases have another property: they react with each other to make water and an ionic compound called a salt. A salt, in chemistry, is any ionic compound made by combining an acid with a base. A reaction between an acid and a base is called a neutralization reaction and can be represented as follows: acid + base H2O + salt The stoichiometry of the balanced chemical equation depends on the number of H+ions in the acid and the number of OH ions in the base. Q: What type of ionic compound is formed from acid and bases reacting with each other? A:

OPTIONS:
- isolated
- common
- dry
- salt

Answer:
salt
