5) Betty the botanist wanted to test the effects of chlorine on plants. To do this, Betty added chlorine
to the water she used to water the plants. She used five identical plants, which were planted in the
same type of pot with the same type of soil, and each was exposed to the same amount of sunlight.
Betty gave each plant the same amount of water. However, to the first plant's water she added 10
grams of chlorine, to the second plant's water she added 8 grams of chlorine, to the third plant's
water she added 6 grams of chlorine, to the fourth plant's water she added 4 grams of chlorine, and

fifth was fine
