Question ID:PT89 S4 Q16 Passage:In an effort to boost milk production, some dairy farmers are treating cows with a genetically engineered hormone called BST. Consumer groups have opposed the use of BST even though the milk of BST-treated cows is identical in nutritional value to that of untreated cows; the treated cows run a greater risk of infection and hence are more likely to be given antibiotics, which may show up in their milk. In high levels, these antibiotics may be harmful to humans. Yet the milk of treated and untreated cows alike is regularly screened for antibiotics. Stem:Which one of the following is most strongly supported by the information above? Correct Answer Choice:DChoice A:Consumer groups have no legitimate reasons for opposing the use of BST. Choice B:Milk from BST-treated cows is as safe for human consumption as that from untreated cows. Choice C:There is no advantage to the use of BST on dairy cows. Choice D:Milk from BST-treated cows can be presumed safe for humans only if it is successfully screened for high levels of antibiotics. Choice E:The only threat posed by drinking milk from cows treated with BST is high levels of antibiotics.
