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.
Which one of the following is the most logical and rational inference that can be made from the above passage?
- Farmers who modernize their methods and diversify their fields will be in an advantageous position in future.
- Climate change will adversely affect the crop diversity.
- Shifting major crops to new croplands will lead to a gr t increase in the total area under cultivation and thus an increase in overall agricultural production.
- Climate change is the most important factor affecting the agricultural economy in the future.
The correct option is A.
