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).
One example: Paragraph: Many of the worlds people live with water scarcity, and that percentage will increase as populations increase and climate changes.

 Choices: A)scarce 
B)plentiful

 Question: A small container that has 100 hydrogen ions is sitting near a larger container that has 2 hydrogen ions. The solution in the larger container is 
 Choices: A)more acidic
