Correct Option (A)
Assumption 1 is valid. The passage highlights several critical issues indicating a future challenge in food production. These include the stagnation of yields for staple crops like rice and wheat, the limited availability of new arable land, and the projected negative impact of rising global temperatures on farming suitability. The discussion of technological applications and improved agricultural practices to increase food availability for humanity further underscores that growing enough food for future generations is indeed perceived as a challenge.
Incorrect Options:
Assumption 2 is not valid. The passage does not advocate for or even mention corporate farming as a solution for food security in poor countries. Instead, it focuses on adapting agricultural technology, extending existing best practices to "small holders and subsistence farmers of Africa and Asia," and improving infrastructure such as roads and storage facilities. The emphasis is on empowering small-scale farmers rather than promoting corporate farming models.
