    Most older antiques are the most valuable. Most antique dealers authenticate. Since the end of the first claim isn't the start of the second claim, we don't have a match for the original. No need to keep reading.

  2. Bad Premise Match13% picked this

    Antique dealers who authenticate the age of the antiques they sell typically have plenty of antiques for sale. Since the most valuable antiques are

    Only one of the premises is a "most" claim. The other is a conditional. Most authenticators have plenty of items for sale. Most valuable item → item was authenticated We can stop reading there.

    Why this is right

    Most dealers carry authenticated items. Most authenticated items are valuable.

    We wanted two "most" premises. This gives us one "many" and one "most". That's enough reason to dislike this one, but if we dug in deeper we would see there's also no overlapping term. Most dealers have lots of valuable items. Many antiques increase value via authentication. "lots of valuable items" ≠ "increase in value via authentication. The second claim doesn't pick up where the first one left off. Let's get out of here.
