To show that improvement in crop yields can properly be attributed to the new drought resistance quality of the hybrid seed we need to show whether any other factor is possible which might have made the impact due to which crop yields significantly improved across the country.

So option B, the answer to question Has there been a significant change in the local weather patterns, particularly in rainfall amounts, in the last two years would be helpfu to evaluate the answer. If ans is yes it means actually rain contributed to yield improvement and if ans is No, it means hybrid seed contributed to yieield improvement.

Thanks

12 Days of Christmas 2024 - 2025 Competition with $40,000 of Prizes

Agricultural Researcher: After several years of declining crop yields due to droughts, Country A’s research center introduced a new hybrid seed specifically designed to be more drought-resistant. Before the introduction of the hybrid seed, farmers used a variety of traditional seeds that had varying levels of drought tolerance. After adopting the new hybrid seed, crop yields significantly improved across the country.

It would be most helpful to find out which of the following in order to assess whether the improvement in crop yields can properly be attributed to the new drought resistance quality of the hybrid seed?

(A) What proportion of the farmers' total expenditure is spent on purchasing seeds?
(B) Has there been a significant change in the local weather patterns, particularly in rainfall amounts, in the last two years?
(C) Among all the crops planted, which seed type accounts for the largest proportion of the yield improvement?
(D) Do any farmers continue to use traditional seeds along with the new hybrid seeds?
(E) Are there more farms specializing in crops that are traditionally drought-resistant or in those that are typically more water-dependent?
