   Clinical trials involving patients from several hospitals are never conducted solely by physicians from

   We were told that trials involving patients from several hospitals are usually coauthored by physicians from separate hospitals. We wouldn't be able to say with 100% certainty that they are never authored by physicians from only one hospital.

   We have two examples (the 2nd and 3rd sentences) in which an article that stems from different institutions usually has multiple authors. 2nd - Reports from clinical trials of different institutions usually have multiple authors. 3rd - And physics papers about results from different institutions usually have multiple authors. But this answer reverses that and says that, "reports with multiple authors usually come from several different institutions". Saying that "American Presidents are usually right handed people" is very different from saying "right handed people are usually American Presidents". "When there's a surfing competition, the weather is usually pretty warm" is very different from "When the weather is pretty warm, there's usually a surfing competition". Saying "Most A's are B" isn't the same as "Most B's are A".

   Physics papers authored by researchers from multiple laboratories usually report results from experiments using subsystems

   We know that "reports involving subsystems from different labs, usually have authors from each lab". But this is saying, "papers with authors from each lab usually are reports involving subsystems". We can't reverse the order of a Most statement and know that it's still true. Most Senators are men ?

   Most technical articles are authored solely by the researchers who conducted the experiments

   We don't have any information that would allow us to derive whether more than 50% of technical articles are [anything]. We were never told "most technical articles are X", or "technical articles are usually X", so we don't have anything resembling this type of claim.
