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).

Ex 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

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


Ex Input:
Paragraph: Objects that are closer together have a stronger force of gravity between them.
 Question: Ferb and Honey are walking towards each other. What is true about the force of gravity between them as the distance between them decreases? 
 Choices: A)it increases 
B)it decreases

Ex Output:
it increases


Ex Input:
Paragraph: Machines make work easier by increasing the amount of force that is applied, increasing the distance over which the force is applied, or changing the direction in which the force is applied.
 Question: John observed that machines are very helpful in performing work because they increase the amount of force, and also make the distance the force is applied 
 Choices: A)Greater 
B)Lesser

Ex Output:

Greater
