Which shower would most likely be the control group in this
study?
Mildew is a fungus that grows in wet areas and can slowly
grow from microscopic to large stains in showers and sinks
Researchers are studying different sprays that could be used
to slow down the growth of mildew. They set up different
showers that are exactly the same and expose them each to
water with the same microscopic amount of mildew. They
then spray some showers with mildew-preventing sprays and
observe how fast mildew grows over time.
O the shower sprayed with many test sprays
the shower not exposed to any mildew at all
O the shower not sprayed with any mildew-preventing spray
O the shower sprayed with a test spray that is already
known to work
