Muskmelons harvested immediately after several days of heavy rain are generally less sweet, and thus less flavorful, than are muskmelons harvested after drier weather. The traditional explanation holds that excess water in the fruit dilutes the sugar. A recently proposed explanation is that excess water in the soil interferes with the plant`s normal ability to produce sugar. Thus, to satisfy its energy needs, the plant draws off sugar it had previously stored in its fruit.
Which of the following issues would it be most helpful to resolve in order to choose between the two explanation offered?
-
AWhether ripe muskmelons harvested shortly after a heavy rain are generally heavier than ripe muskmelons of the same variety harvested in a period of drier weather
-
BWhether fruits of other plants, such as strawberries, also tend to be less sweet if harvested after periods of heavy rain
-
CWhether fruits of plants that are grown under very dry conditions tend to be very sweet
-
DWhether muskmelons left on the vine for a week or more often the end of a period of heavy rain turn out to be as sweet and flavorful as muskmelons harvested in a period of dry weather
-
EWhether some varieties of muskmelons tend to be sweeter or more flavorful than other varieties
