Derek lives in a hot, humid climate. He has two rose bushes in pots in his yard. The rose bushes grow quickly and bloom with large, red roses. Derek moves to a cold, dry climate at the same altitude and notices that his rose bushes stop growing and do not have large blooms. He hypothesizes that the rose bushes are not receiving enough water because he is now in a dry climate. He waters them more often, but they do not improve.
Which of the following scientific questions should he ask next to find out what is wrong with his roses?
A. Does temperature affect the growth of the rose bushes?
B. Do rose bushes grow better in high or low altitudes?
C. Which rose bush has larger, more colorful blooms?
D. How much do rose bushes cost in his new area?
