Which statement is scientifically reasonable?

in the early 2000s, scientists and farmers began to notice

a sharp decline in the population of honeybees around

the world. many explanations were proposed for the

cause of the decline. three possible explanations were

pesticides on crops, parasites in beehives, and cell phone

tower signals.

one study showed that pesticides were affecting

bee populations near one farm. therefore,

pesticides on crops is the only reasonable

explanation

a post online claims, "many people thought that cell

phone signals were confusing the bees' sense of

navigation." therefore, cell phone signals is the

best explanation

multiple scientific experiments need to be

conducted to determine whether these possible

causes are affecting bee populations
