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 Input: Paragraph: Larger telescopes can collect more light and see finer details than smaller telescopes.
 Question: One reason scientists sometimes use smaller telescopes for bright objects is because they collect 
 Choices: A)more light 
B)less light
Example Output: less light

Example Input: Paragraph: The closer objects are, the stronger the gravitational pull between them.
 Question: Mary is looking through her new telescope. She sees some objects in space that are exerting gravitational pulls on each other. If the first two objects are 50,000 miles apart, and the second set of objects are 100,000 miles apart from each other, then the gravitational pull of the first set of objects is 
 Choices: A)greater 
B)less.
Example Output: greater

Example Input: Paragraph: Shorter wavelengths (higher frequencies) correspond to higher energies and thus hotter star temperatures.
 Question: Don is sending out wavelengths, and wants them to correspond to lower energies. In order to best do this, Don will send out wavelengths that are 
 Choices: A)longer 
B)shorter
Example Output:
longer
