Answer:
1. More pollination processes in the regular corn planted in field A than in field B.
2. Low pest and insect attack on corn planted in field A compared to B.
1. Pollination is the process in which a plant becomes fertilized, so as to produce seeds. The process requires some agent which could be; air, the human, wind, etc.
Therefore more pollination of the corn planted in field A than those in B would lead to more yield (ears of corn harvested) than that of B.
2. Pests and insects are agents which could reduce the yield of corn after harvest. Comparing the two fields A and B, if the corn planted in field A were not affected by pests or insects, while those planted in B were affected, then more ears of corn would be harvested in field A.
Final Answer = it's a and d obviously the price of the corn doesn't make the corn be planted differently.
