Sarah is testing different types of planting soil to determine which type is most effective in growing blueberry bushes. She purchases two different brands of planting soil from a local store. Sarah applies Brand A to 1 area of the yard and Brand B to another area of the yard, both of which receive full sunlight. She waters the area with Brand B daily; she waters the area with Brand A every other day. At the end of the study, Sarah concludes Brand B is more effective in growing blueberry bushes. Why is her conclusion not valid

what are the options?
it says that she watered the brand B plant every single day while she only watered the brand A plant every other day - if she wants to compare how Brand A and Brand B are different, she needs to give each plant the same amount of water
(this process is called "controlling for variables")
so her conclusion is not valid because she needs to give each plant the same amount of water
