In an effort to boost milk

   Too Strong: no legit reasons6% picked this

   Consumer groups have no legitimate reasons for opposing the use

   The final sentence does tamp down the fear about antibiotics ending up in our milk, but it's much stronger to suddenly say there are zero legitimate reasons for opposing the use of BST. Maybe BST does a lot of other weird things to cows or has bad environmental effects or has other health threats to humans.

   Too Strong: as safe20% picked this

   Milk from BST-treated cows is as safe for human consumption as that

   We know that BST-cows are more likely to get antibiotics and that it would be bad for humans to consume milk with antibiotics in it. So just that already makes it hard to sign off on an extreme comparison that BST-milk and untreated milk is equally safe. And even if the milk is screened, that would only tell us that antibiotics aren't a safety threat. There might be other safety threats that weren't discussed by the passage.

   There is no advantage to the use of BST on

   Too Strong: no advantage Opposite, if anything It's hinted at that there is an advantage to the use of BST. It's thought to potentially boost milk production. We don't have any way to support the strong claim that there is no advantage to the use of BST.

   Milk from BST-treated cows can be presumed safe for humans only if it is successfully screened for

   Why this is right

   This is definitely very strongly worded. But ultimately it's our most supportable answer. The contrapositive would say, "If milk from BST-cows has not been successfully screened for high levels of antibiotics (i.e. the test showed it does not have high antibiotics", then you can't presume it's safe". This idea isn't as strong as it first looks because the conditional isn't saying that the milk is or isn't safe. It's talking about whether it would be safe to presume it's safe. You can "presume" something is safe if you have no reason to think it might be unsafe. But we do have a reason to think that BST might be unsafe. BST cows are more often given antibiotics, which can show up in milk and which can be harmful to humans if they show up in high levels. So this answer is really just saying, "If you haven't already screened this BST milk for high antibiotics and determined that it is free from antibiotics, then you should know that there is a chance it is high in antibiotics in a harmful way."

   Too Strong: the only6% picked this

   The only threat posed by drinking milk from cows treated with BST is high

   Just because high antibiotics is the only threat that was discussed doesn't mean we can infer that it's the only possible threat from BST milk.
