input with options: Answer the following question given this paragraph: A concave mirror is shaped like the inside of a bowl. The type of image it forms depends on where the object is relative to the focal point. The image may be real, upside down, and reduced in size; or it may be virtual, right-side up, and enlarged. Q: What do you call a mirror shaped like the inside of a bowl? A:
OPTIONS:
- convex
- circular
- curved
- concave
output: concave

Q: Answer the following question given this paragraph: As the atoms approach one another, their electron clouds gradually begin to overlap. Now there are several interactions which begin to occur. One is that the single electrons that each hydrogen atom possesses begin to repel each other. This repulsive force would tend to make the potential energy of the system increase. However, the electron of each atom begins to be attracted to the nucleus of the other atom. This attractive force tends to make the potential energy of the system decrease. Q: As the atoms approach one another, their electron clouds gradually begin to do what? A:

OPTIONS:
- magnetize
- shrink
- disappear
- overlap

A: overlap

input: OPTIONS:
- isolated water
- clean water
- applied water
- strong water Now, answer this question: Answer the following question given this paragraph: Nitrogen Oxyacids and Salts Nitrogen pentaoxide, N2O5, and NO2 react with water to form nitric acid, HNO3. Alchemists, as early as the eighth century, knew nitric acid (shown in Figure 18.50) as aqua fortis (meaning "strong water"). The acid was useful in the separation of gold from silver because it dissolves silver but not gold. Traces of nitric acid occur in the atmosphere after thunderstorms, and its salts are widely distributed in nature. There are tremendous deposits of Chile saltpeter,. Q: Alchemists, as early as the eighth century, knew nitric acid as aqua fortis, which means? A:
A:
output: strong water

Answer the following question given this paragraph: Reverse transcription also occurs with retrotransposons and during telomere synthesis in eukaryotes. Retrotransposons are self-replicating segments of eukaryotic genomes that use reverse transcriptase to move from one position in the genome to another via a RNA intermediate. A telomere is a region of repetitive noncoding nucleotide sequences at each end of a chromosome. These sequences protect the end of the chromosome from deterioration or from fusion with neighboring chromosomes. Each time DNA is replicated, small segments of DNA from the ends of the chromosome is lost. Telomerase is a reverse transcriptase that uses an RNA intermediate to elongate the 3' end of DNA strands in the telomere regions after each replication cycle. Q: What is a region of repetitive noncoding nucleotide sequences at each end of a chromosome? A:

OPTIONS:
- diploid
- cellular
- cytoskeleton
- telomere

Answer: telomere

Problem: OPTIONS:
- primitive
- primordial
- distinctive
- vestigial
Q: Answer the following question given this paragraph: Penguins do not use their wings, known as flippers, to fly in the air. However, they do use them to move in the water. The theory of evolution suggests that penguins evolved to use their wings for a different purpose. A whale's pelvic bones, which were once attached to legs, are also vestigial structures. Whales are descended from land-dwelling ancestors that had legs. Q: What do you call structures like a whale's pelvic bones, which were once attached to legs, or wings that cannot be used for flight? A:
Answer: vestigial

Answer the following question given this paragraph: Meningitis is an infection of the membranes that cover the brain and spinal cord. If you have meningitis, you are likely to have a fever and a headache. Another telltale symptom is a stiff neck. Meningitis can be caused by viruses or bacteria. Viral meningitis often clears up on its own after a few days. Bacterial meningitis is much more serious ( Figure below ). It may cause brain damage and death. People with bacterial meningitis need emergency medical treatment. They are usually given antibiotics to kill the bacteria. Q: Meningitis is an infection of the membranes that cover the brain and what else? A:

OPTIONS:
- umbilical cord
- notochord
- liver
- spinal cord

Answer:
spinal cord
