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. Therefore, the government should increase funding for research into new ways to improve yields.
premise: The land that we cultivate grain crops( rice, wheat, and corn) will have to increase to maintain level of caloric intake and pace with global population because the cultivated land is diminishing.
Conclusion: The government should increase funding for research into new ways to improve produce these grain crops. it is a sort of recommendation given by author. and he is assuming that this is best way to achieve this plan. lets see options choice
Which of the following is an assumption on which the farmer's argument depends?
A. It is solely the government's responsibility to ensure that the amount of rice, wheat, and corn produced worldwide keeps pace with global population growth.
We aren't concerned about what is the only responsibility of government . it also uses a extreme language{all,any,no, only, every,never, alwyas} be careful
when you see the extreme language used in the options choice.
B. 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.
this is what exactly we are assuming. let's negate it.
Increasing government funding for research into new way to improve the yields per acre of rice, wheat, and corn corps
would NOT help
to increase the world wide annual production of food from these crops. if the increasing funding for research would not help to increase the world production of
food , then what is value of increasing government funding for research, as to author, so it completely destroys the author conclusion. that's why Author must
assume prepositions to reach to the conclusion.
C. Increasing the yields per acre of rice, wheat, and corn is more important than increasing the yields per acre of other crops.
there is no discussion about to other crops, so c is out.
D.
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.
does the author is talking about the specific type of research in the passage no, that's why (d) is out.
E. In coming decades, rice, wheat, and corn will become a minor part of human caloric intake, unless there is government-funded research to increase their yields per acre.
let's discuss this options choice it's confusing
if there isn't government-funded research to increase their yields per acre, rice, wheat, and corn will become a minor part of human caloric intake, In coming
decades.
author is discussing here every year not a decade, we don't what could happen in the future,? other reason
lets negate this options choice,
if there is government-funded research to increase their yields per acre, rice, wheat and corn will become a minor part of human caloric intake, in coming ten
year. does it weaken the author's conclusion? no way.
what rice, wheat and corn will become a minor part of human caloric intake, in coming ten year? is the author is really assuming that if government-funded
research to increase their yields to get the result in ten year. no? why , but the passage stated that every year land will have to increase 1.5 percent to maintain
demand of people of the world.
