Mr. Krabbs wants to make Bikini Bottoms a nicer place to live. He has created a new sauce that he thinks will reduce the production of body gas associated with eating crabby patties from the Krusty Krab. He recruits 100 customers with a history of gas problems. He has 50 of them (Group A) eat crabby patties with the new sauce. The other 50 (Group B) eat crabby patties with sauce that looks just like new sauce but is really just a mixture of mayonnaise and food coloring. Both groups were told that they were getting the sauce that would reduce gas production. Two hours after eating the crabby patties, 30 customers in group A reported having fewer gas problems and 8 customers in group B reported having fewer gas problems.

Which is the CONTROL group?

• Group A

• Group B

• Mr. Krabbs

Read the following paragraph on how the body maintains homeostasis.

Have you ever been swimming with your friends and had a contest to see who could stay under water the longest?  If you have, then you know something about homeostasis.  Imagine taking that deep breath before diving under water.  You inhale and hold your breath.  The oxygen levels in your blood begin to decline and carbon dioxide levels begin to rise.  Sensors in your body alert the brain as oxygen and carbon dioxide levels are not normal.  Messages move through your nervous system to the diaphragm and rib cage.  Those muscles relax, forcing you to exhale.  You jump up above water, as the same muscles contract, and you inhale deeply.  You continue to inhale and exhale more deeply and rapidly than normal until oxygen and carbon dioxide levels return to their set points.

Which of the following sentences could be added to the end of the paragraph above?

• 1. You will continue to breathe rapidly until you leave the pool.

• 1. When oxygen and carbon dioxide levels are restored, normal breathing resumes.

• 1. Regular breathing levels resume before oxygen levels are restored to normal.
