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 regions herbicide - tolerant cotton was affected. however, the problems may have

this information appears on page 15 of the source. which citation format is correct?
(price 15)
(price et al.15)
(price and lin et al. 15)
(price, lin, falck - zepeda et al.15)

Explanation:

• For the first question:
• The original text says "a 17 - percent increase in yields for herbicide - tolerant cotton adopters nationwide".
• The second option "One study found a 17% increase in cotton yields using a genetically modified variety" is a paraphrase as herbicide - tolerant cotton is a type of genetically modified variety.
• The first option is wrong as it says "17% less" which is opposite. The third option just repeats the "ARMS effect" term without proper paraphrasing.
• For the second question:
• In citation, when there are multiple authors, the correct format is to list the first author followed by "et al." (which means "and others").
• Here, if the main author is Price (assuming from the options), the correct citation format is (Price et al. 15) as it follows the standard academic citation style for multiple - author works.

Answer:

• First question: One study found a 17% increase in cotton yields using a genetically modified variety.
• Second question: (Price et al. 15)
