Question: Answer the following question given this paragraph: The new cells gradually move up through the epidermis toward the surface of the body. As they move, they produce the tough, fibrous protein called keratin. Q: What is the most common cause of lung cancer? A:
OPTIONS:
- coal smoke exposure
- restaurant smoke exposure
- tree smoke exposure
- tobacco smoke exposure
Answer: tobacco smoke exposure

input with options: Answer the following question given this paragraph: ♦️ Many industrial processes for preparing compounds use "continuous-flow reactors," which are chemical reaction vessels in which the reactants are mixed and allowed to react as they flow along a tube. The products are removed at a certain distance from the starting point, when the reaction is nearly complete. The key operating parameters in a continuous-flow reactor are temperature, reactor volume, and reactant flow rate. As an industrial chemist, you think you have successfully modified a particular process to produce a higher product yield by substituting one reactant for another. The viscosity of the new reactant is, however, greater than that of the initial reactant. Q: Continuous-flow reactors are chemical reaction vessels in which the what are mixed and allowed to react as they flow along a tube? A:
OPTIONS:
- reactives
- generators
- propellants
- reactants
output: reactants

Q: Answer the following question given this paragraph: Isotopes of Hydrogen Hydrogen, the most abundant element in the universe, is the ultimate source of all other elements by the process of nuclear fusion. (For more information on nuclear fusion, seeChapter 20 "Nuclear Chemistry". ) Table 21.2 "The Isotopes of Hydrogen" compares the three isotopes of hydrogen, all of which contain one proton and one electron per atom. The most common isotope is protium (1H or H), followed by deuterium (2H or D), which has an additional neutron. The rarest isotope of hydrogen is tritium (3H or T), which is produced in the upper atmosphere by a nuclear reaction when cosmic rays strike nitrogen and other atoms; it is then washed into the oceans by rainfall. Tritium is radioactive, decaying to 3He with a half-life of only 12.32 years. Consequently, the atmosphere and oceans contain only a very low, steadystate level of tritium. The termhydrogen and the symbol H normally refer to the naturally occurring mixture of the three isotopes. Table 21.2 The Isotopes of Hydrogen. Q: What is the most abundant element in the universe? A:

OPTIONS:
- carbon
- helium
- nitrogen
- hydrogen

A: hydrogen

input: OPTIONS:
- conjuration
- interconnection
- specmutation
- coevolution Now, answer this question: Answer the following question given this paragraph: Coevolution occurs when species evolve together. This often happens in species that have symbiotic relationships. Examples include flowering plants and their pollinators. Q: What is the term for species evolving together? A:
A:
output: coevolution

Answer the following question given this paragraph: Humid subtropical climates are found on the eastern sides of continents between about 20 and 40 latitude. The southeastern U. S. has this type of climate. Summers are hot and humid, but winters are chilly. There is moderate rainfall throughout the year. Pine and oak forests grow in this climate ( Figure below ). Q: Where can you find humid subtropical climates? A:

OPTIONS:
- between 20 and 40 degrees longitude
- between 40 and 60 degrees latitude
- between 40 and 60 degrees longitude
- between 20 and 40 degrees latitude

Answer: between 20 and 40 degrees latitude

Q: Answer the following question given this paragraph: Renewable resources can be renewed as they are used. An example is timber, which comes from trees. New trees can be planted to replace those that are cut down. Sunlight is a renewable resource. It seems we will never run out of that!. Q: Timber, obtained from trees that can be replanted to replace those that are cut down, is an example of what type of resource? A:

OPTIONS:
- nonrenewable
- fossil fuel
- mineral
- renewable

A:
renewable
