input with options: Answer the following question given this paragraph: The vertebrate endoskeleton is made of bone and cartilage. Cartilage is a tough, flexible tissue that contains a protein called collagen. Bone is a hard tissue consisting of a collagen framework that is filled in with minerals such as calcium. Bone is less flexible than cartilage but stronger. A bony endoskeleton allows an animal to grow larger and heavier than a cartilage endoskeleton would. Bone also provides more protection for soft tissues and internal organs. Q: The vertebrate endoskeleton is made of bone and what tough, flexible tissue? A:
OPTIONS:
- cuticle
- collagen
- synovial tissue
- cartilage
output: cartilage

A dilute solution has a low concentration of solute. A concentrated solution has a high concentration of solute. Q: What term describes the amount of solute in a given amount of solution? A:
A:
output: concentration

Answer the following question given this paragraph: In arid regions, a mountain stream may flow onto flatter land. The stream comes to a stop rapidly. The deposits form an alluvial fan ( Figure below ). Q: When a mountain stream flows onto flatter land and comes to a stop rapidly, what do the deposits form? A:

OPTIONS:
- conical fan
- vertical fan
- upstream fan
- alluvial fan

Answer: alluvial fan

Problem: OPTIONS:
- kidney
- liver
- bone
- spleen
Q: Answer the following question given this paragraph: Figure 42.21 The spleen is similar to a lymph node but is much larger and filters blood instead of lymph. Blood enters the spleen through arteries and exits through veins. The spleen contains two types of tissue: red pulp and white pulp. Red pulp consists of cavities that store blood. Within the red pulp, damaged red blood cells are removed and replaced by new ones. White pulp is rich in lymphocytes that remove antigen-coated bacteria from the blood. (credit: modification of work by NCI). Q: What organ is similar to a lymph node but is much larger and filters blood instead of lymph? A:
Answer: spleen

Answer the following question given this paragraph: Physical chemistry is the study of macroscopic properties, atomic properties, and phenomena in chemical systems. A physical chemist may study such things as the rates of chemical reactions, the energy transfers that occur in reactions, or the physical structure of materials at the molecular level. Q: What is the study of macroscopic properties, atomic properties, and phenomena in chemical systems? A:

OPTIONS:
- differential chemistry
- thermal chemistry
- molecular chemistry
- physical chemistry

Answer:
physical chemistry
