QUESTION TEXT: In an effort to boost milk production,…
QUESTION TYPE: Most Strongly Supported
FACTS:
- Some dairy farmers are treating cows with a genetically engineered hormone called BST.
- Consumer groups have opposed the use of BST.
- BST-treated cows produce milk with the same nutritional value as milk from untreated cows.
- Treated cows run a greater risk of infection.
- Treated cows are more likely to be given antibiotics.
- The antibiotics may show up in milk.
- These antibiotics, at high levels, may be harmful to humans.
- The milk of treated and untreated cows is screened regularly for antibiotics.
ANALYSIS: Lots of facts here. Make sure you’ve got them all straightened out, and then look at the answers. Remember that it’s hard to prephrase for Most Strongly Supported questions; you have to come in and consider which answer is best.
___________
- We don’t know all the reasons consumer groups oppose the use of BST, so it’s hard to say that there are no legitimate reasons.
- We can’t conclude this. We know that both are screened for antibiotics, but there may be other hazards in milk from treated cows that is absent from untreated cows’ milk.
- This definitely doesn’t follow. We’re explicitly told that BST is used in an effort to boost dairy production, and aren’t given a reason to doubt that.
- CORRECT. We’re told that treated cows are more likely to be given antibiotics, which can be harmful to humans if it shows up in the milk. The milk must be screened, therefore, in order to be sure that it’s safe.
- Similar to B, we don’t know that there aren’t other problems with BST milk. We’re only told about one.
