ok... I got 37. Not bad for my first 6 months of keeping bees. That said I agree with MB's comment that it is important to give their answer not the correct one.
The use of chemicals in a hive of honey bees is regulated by:?
a. instructions provided by the seller
b. the label of the product
c. the way the beekeeper uses the product
d. none of these
Ultimately, the beekeeper using the product regulates its use. I don't use chemicals except sugar but just because it has a label doesn't mean that they will be used in accordance with the label. That would have been 38... Still looking at some of the others I got wrong.
