Question

the estimated arms effect indicates a 17 - percent increase in yields for herbicide - tolerant cotton adopters nationwide. in some regions, herbicide - tolerant cotton yields may have been lower than for conventional varieties. in particular, farmers in the mississippi portal encountered serious and unexpected problems with their herbicide - tolerant cotton during the 1997 growing season (virginia cooperative extension). some growers found deformed bolls and bolls that dropped off the plants. about 20 percent of the region’s herbicide - tolerant cotton was affected. however, the problems may have
according to the passage, what is one benefit of genetically modified cotton?
increased resistance to drought and disease
increased yields in all areas of the nation
increased yields in some areas of the nation
it may have caused problems with the plants.
it grows in only certain types of soil.

Explanation:

The text mentions "the estimated ARMS effect indicates a 17 - percent increase in yields for herbicide - tolerant cotton adopters nationwide". This shows that genetically - modified (herbicide - tolerant) cotton has an increase in yields. Although it also mentions that in some regions (like the Mississippi Portal) there were problems, the overall national - level benefit is an increase in yields. The option "increased yields in some areas of the nation" is incorrect as the text says "nationwide" for the yield increase (the problem areas are exceptions). The options about drought and disease resistance and soil - type limitation are not mentioned in the provided text.

Answer:

increased yields in all areas of the nation
