According to local farmers, the recent significant decline in the yield of Einkorn, a variety of wheat cultivated primarily in Ingrostia, is due to
the unfavorable weather conditions last year.
However,
a government spokesperson recently made a statement claiming that
the yield of Einkorn has declined because of the decline in the usage of pesticides by the local farmers.
Which of the following, if true, most seriously calls the spokesperson’s claim into question?
We need to find an answer choice that undermines the spokesperson's claim.
(A) Weather conditions in Ingrostia have been the same this year as they were last year.
The government spokesperson's claim is about decline in the usage of pesticides. A is not relevant.
(B) Einkorn has been losing its popularity to another variety of wheat called Durum that
requires cheaper seeds and fewer fertilizers. Again, this answer choice is about some other variety of wheat that requires cheaper seeds and fewer fertilizers. Pesticides is not even mentioned here. B is not relevant.
(C) The yield of Spelt, a variety of wheat grown in Ingrostia that requires the same weather conditions as Einkorn but is extremely resistant to pests has also declined. Correct. Since the yield of the other variety of wheat which is extremely resistant to pests (implies it doesn't need much use of pesticides) has also declined - this option undermines the government spokesperson's claim and strengthen's the claim of local farmers. Correct.
(D) The spokesperson is not from an agricultural background, whereas the farmers are more knowledgeable about agricultural conditions - irrelevant
(E) The global yield of Einkorn has been lower this year than in the previous years. - irrelevant.
Answer C
