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).

Input: Consider Input: Paragraph: At higher concentrations, particles of reactants are crowded closer together, so they are more likely to collide and react.
 Question: Ian sees an object with few colliding particles, and he compares it to another object with few colliding particles. Which is true about the objects? 
 Choices: A)the object with many colliding particles has a lower concentration of particles 
B)the object with many colliding particles has a higher concentration of particles

Output: the object with many colliding particles has a lower concentration of particles


Input: Consider Input: Paragraph: The size of an ocean wave depends on how fast, over how great a distance, and how long the wind blows. The greater each of these factors is, the bigger a wave will be.
 Question: Phil surfed huge 15 foot waves on the beach. _____ wind speeds likely contributed to such large waves 
 Choices: A)high 
B)low

Output: high


Input: Consider Input: Paragraph: The closer the charged objects are, the stronger the electrostatic force.
 Question: Will was pulling some magnets apart. When is the electrostatic force the highest? 
 Choices: A)when the magnets are close 
B)when the magnets are far


Output: when the magnets are close
