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:
OPTIONS:
- antifreeze
- dry ice
- fluorocarbons
- liquid nitrogen
liquid nitrogen

OPTIONS:
- reactions
- organisms
- Proteins
- isotopes

Answer: isotopes

Question: Answer the following question given this paragraph: Mole fractions describe the fraction or percentage of a mixture that is made up of a particular substance. Q: What describe the fraction or percentage of a mixture that is made up of a particular substance. A:
OPTIONS:
- molecular scale
- atomic weight
- solute level
- mole fractions

input with options: Answer the following question given this paragraph: Lysosomes are vesicles that are formed by the Golgi apparatus. They contain powerful enzymes that could break down (digest) the cell. Lysosomes break down harmful cell products, waste materials, and cellular debris and then force them out of the cell. They also digest invading organisms such as bacteria. Lysosomes also break down cells that are ready to die, a process called autolysis. Q: What is the name of vesicles that are formed by the golgi apparatus? A:
OPTIONS:
- vessels
- lymphocytes
- capillaries
- lysosomes
output: lysosomes

Q: Answer the following question given this paragraph: Logging, mining, construction, and paving surfaces are some of the ways that soil erosion increases. Q: What is aggravated by practices such as logging, mining, construction, and paving surfaces? A:

OPTIONS:
- global warming
- seismic activity
- water pollution
- soil erosion

A: soil erosion

Answer the following question given this paragraph: Q: What do hydrophilic substances have an affinity for? A:
