pls answer asap

Use the following passage to answer the next 4 questions.
A farmer who grows blackberries has found his harvest to be lower than usual. He suspects that some
animals are eating the berries before he can pick them. The farmer thinks it may be either birds (landing
on the bushes to feast on berries) or rodents (climbing the bushes from below to munch on berries). He
decides to first test the hypothesis that birds are eating his berries, and consults with a local expert
on how best to prevent the birds from eating berries. He has eight fields with 10 rows of berry bushes in
each field. In one of his fields (depicted below, as viewed from above), he covers half of the rows with
nets that will prevent birds from landing on the bushes, and he leaves the other half uncovered. Over
the course of 8 weeks, he counts the berries harvested from each row of bushes in the test field.

Q3.6. The farmer's experiment was widely considered to be well-designed and well-implemented.
After 8 weeks, he found no difference between groups, and the berry harvest was still lower than
in previous years. What can he conclude about his hypothesis?
Rodents are eating the berries.
Birds are eating the berries.
Birds are not eating the berries.
The results do not address the hypothesis.
