Given the task definition, example input & output, solve the new input case.
You are given a short paragraph, a question and two choices to answer from. Choose the correct answer based on the paragraph and write the answer(not the key).
Example: Paragraph: Many of the worlds people live with water scarcity, and that percentage will increase as populations increase and climate changes.
 Question: John's town used to have lots of water, back when there were only a few hundred people. However, now that the town holds several thousand people, the water availability is 
 Choices: A)scarce 
B)plentiful
Output: scarce
Based on the information given in the paragraph, population growth will make water more scarce, so that is the correct answer.

New input case for you: Paragraph: When a person smokes there are chemicals released by the tobacco that enter the lungs. Because the lungs have to work harder to remove the chemicals, the body has to work harder to get the air needed to survive.
 Question: If the amount of chemicals inside of Jim's lungs decreases, what will happen to the amount of air his lungs can process? 
 Choices: A)increase 
B)decrease
Output:
increase
