When we claim "A must have caused B," then one way to weaken it is by claiming that "C could have caused B."
Here support for the researcher's claim is "N taken with Morphine reduces blood poisoning incidents" which as per author implies that N kills the bacteria.
But if we provide an alternative cause for reduction in blood poisoning (N inhibits morphine from triggering migration), then the claim that 'N kills the bacteria' loses its support. Note that it is still possible that N kills the bacteria but we are to raise doubts on the claim - not try to prove that it must be false.

Here GMAC wants us to make the connection that "Naltrexone will turn out toxic to certain types of bacteria" = Naltrexone kills the bacteria that migrated from intestine into the bloodstream because of morphine, now weaken this statement, too easy now isn't it? Therefore, Naltrexone inhibits morphine from triggering the migration of intestinal bacteria into the bloodstream i.e. it doesn't interact with the bacteria at all.

mice-given morphine- likely to develop blood poisoning.
bacteria respond to morphine by migrating into bloodstream.
but when morphine and naltrexone are given together, blood poisoning is less frequent but it does occur.
researchers prediction- naltrexone will turn out to be toxic to certain types of bacteria.
conclusion- these results provides support to researchers prediction.
A but how does that matter? even if they dont pass into intestine, they can still affect negatively to bacteria. so reject.
B if naltrexone is stoping the morphine then something else is still causing the bacteria to move into blood stream and causing blood poisoning. so this attacks the gap.
C that means even only naltrexone is given or both the effect is almost same. so this rather strengthen it. reject it.
D we are not concerned on what are the other effects of morphine on mice. so reject.
E this is completely out of scope.
