Problem: OPTIONS:
- oceans
- deserts
- equators
- poles
Q: Answer the following question given this paragraph: Much less solar energy gets to the poles. Q: What parts of the planet does solar energy have difficulty reaching? A:
Answer: poles

Problem:OPTIONS:
- interaction mapping
- diagnostic mapping
- chemical mapping
- linkage mapping

Answer the following question given this paragraph: Determining recombination frequencies between genes located on the same chromosome allows a linkage map to be developed. Linkage mapping is critical for identifying the location of genes that cause genetic diseases. Q: What type of mapping is critical for identifying the location of genes that cause genetic diseases? A:
****
A: linkage mapping

Answer the following question given this paragraph: The other idea is that evolution occurs by natural selection. Natural selection is the process in which living things with beneficial traits produce more offspring. As a result, their traits increase in the population over time. Q: Under which process do living things with beneficial traits produce more offspring? A:
OPTIONS:
- migration
- differentiation
- evolution
- natural selection
natural selection

Answer the following question given this paragraph: In a red supergiant, fusion does not stop. Lighter atoms fuse into heavier atoms. Eventually iron atoms form. When there is nothing left to fuse, the star's iron core explodes violently. This is called a supernova explosion. The incredible energy released fuses heavy atoms together. Gold, silver, uranium and the other heavy elements can only form in a supernova explosion. A supernova can shine as brightly as an entire galaxy, but only for a short time, as shown in Figure below . Q: What always continues in a red supergiant? A:
OPTIONS:
- heat
- movement
- fission
- fusion

Answer: fusion

Question: Answer the following question given this paragraph: The ancestor of plants is green algae. This picture shows a close up of algae on the beach. Q: Name the plant considered to be the ancestor of plants? A:
OPTIONS:
- brown algae
- ferns
- grass
- green algae
Answer: green algae

input: OPTIONS:
- antifreeze
- dry ice
- fluorocarbons
- liquid nitrogen Now, answer this question: Answer the following question given this paragraph: Magnetic resonance imaging (NMR) devices use liquid nitrogen to cool the superconducting magnets. Nitrogen is a gas at room temperature and liquefies at -195.8C. Its neighbor on the periodic table (oxygen) boils at -182.95C. The interactions between nitrogen molecules (N 2 ) are weaker, so the boiling point is lower. Interactions between non-polar molecules depend on the degree of electron fluctuation within the molecule. Q: Magnetic resonance imaging devices use what to cool the superconducting magnets? A:
A:
output:
liquid nitrogen
