Suffering the impact of swarms of locusts, a farmer uses an airplane to spray an insecticide over 1,500 acres of his corn field. this farmer is trying to address this pest problem by using
select one:
a. an agricultural treatment.
b. integrated pest management.
c. a chemical treatment.
d. an ecological control.

C. a chemical treatment.

Explanation:

In this case we would be talking about a chemical treatment, since the application of an artificial compound is made, and it is not clarified that it was "ecofriendly".

On the other hand, the question clarifies that the farmer is suffering from the plague. This indicates that he is not preventing it (Integrated pest management), he is treating it.

Finally, it should not be considered as an agronomic treatment, since no real modifications are being made to the way the field is managed.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

it's not c. i took the quiz and got it wrong. so my best guess is b.

have a great day, and hope this .
