Sarah was testing paper towels to see which brand was the strongest. She used five brands of towels in her experiment. She wet
the towels and then used them to hold beans. She counted the number of beans the wet paper towels could hold without tearing.
When the experiment was completed, Sarah compared the towel strength using a bar graph. What was her label on the X-axis?
A brand of paper towel
B number of beans
C tearing time
D strength of paper towel
