After reading the paragraph below, answer the questions that follow.

You've been experiencing acid indigestion lately, and you'd like a quick fix for the problem. You do a little research on the Internet and discover that your problem is caused by excess stomach acid. In the pharmacy aisles, however, you're having a little trouble deciding what to purchase to address the problem. At the pharmacy counter, the clerk recommends that you purchase PEPCID AC or Alka-Seltzer tablets.


You want to design a controlled experiment to determine which tablet, PEPCID AC or Alka-Seltzer, neutralizes stomach acid the quickest. Which of the following experiments would be the best to perform?
◦ Place a PEPCID AC tablet in a beaker of acid at pH 2 and an Alka-Seltzer tablet in a separate beaker of acid at pH 2 and record how long it takes for the tablets to dissolve.
◦ Place a PEPCID AC tablet in a beaker of acid at pH 2 and an Alka-Seltzer tablet in a separate beaker of acid at pH 2 and check the pH in the beakers every 2 minutes.
◦ Take a PEPCID AC tablet at 8:00 am on Monday and take an Alka-Seltzer tablet at 8:00 am on Tuesday and take note of how long it takes you to feel better.
◦ Find a group of your friends and go out to a big dinner. Then give half of them a PEPCID AC tablet and give the other half an Alka-Seltzer tablet and tell them to write down how long it takes them to feel better.
