Passage

Climate change may actually benefit some plants by lengthening growing seasons and increasing carbon dioxide. Yet other effects of a warmer world, such as more pests, droughts, and flooding, will be less benign. How will the world adapt? Researchers project that by 2050, suitable croplands for four commodities — maize, potatoes, rice, and wheat — will shift, in some cases pushing farmers to plant new crops. Some farmlands may benefit from warming, but others won’t. Climate alone does not dictate yields; political shifts, global demand, and agricultural practices will influence how farms fare in the future.

Select an option to attempt

Explanation

Statement A is correct. The passage discusses how climate change will bring both benefits (e.g., longer growing seasons, increased CO₂) and challenges (e.g., pests, droughts, flooding). It highlights the need for adaptation, including changing crops and practices. It also states that other factors like political shifts, global demand, and agricultural practices play a role in farm yields, suggesting that farmers who adapt their methods will fare better.

Statement B is incorrect. Because the passage does not explicitly state that crop diversity will be adversely affected.

Statement C is incorrect. Because the passage does not suggest that shifting crops will lead to a large increase in cultivation area or overall production.

Statement D is incorrect. Because the passage explicitly mentions multiple factors, not just climate change, influencing the agricultural economy.
