Farmer: Worldwide, just three grain crops-rice, wheat, and corn-account for most human caloric intake. To maintain this level of caloric intake and also keep pace with global population growth, yields per acre from each of these crops will have to increase at least 1. 5 percent every year, given that the supply of cultivated land is diminishing. Ttherefore, the government should increase funding for research into new ways to improve yields Which of the following is an assumption on which the farmers argument depends? ['Increasing the yields per acre of rice, wheat, and corn is more important than increasing the yields per acre of other crops', 'Increasing government funding for research into new ways to improve the yields per acre of rice, wheat, and corn crops would help to increase total worldwide annual production of food from these crops', 'Current levels of funding for research into ways of improving grain crop yields per acre have enabled grain crop yields per acre to increase by more than 1. 5 percent per year worldwide', 'It is solely the governments responsibility to ensure that the amount of rice wheat, and corn produced worldwide keeps pace with global population growth']
