Like “does the Pope shit in the woods?” or “that train has sailed?”
Also, what good examples can you think of?
No, but if they’re going to assert that cleaning involves liquid, they would be counterexamples to such an assertion.
“dry cleaning” is a specific term for a method of laundering clothes that DOES require a liquid, but not soaking the clothes in water.
Those things you mentioned are not counter examples, because they have nothing to do with “dry cleaning”.
That’s like if I point out that peanuts aren’t actually nuts, and you respond with “but walnuts are nuts!”
Yeah, walnuts are nuts, but that doesn’t have anything to do with peanuts and whether or not they are nuts.
They are focusing on the dry part of the term. Using a liquid during the process goes against the dry part.
I would tend to disagree with the Cambridge example, because liquids can be dry. “Dry” liquids are anhydrous, meaning they’ve been treated to remove any water.
Source: Am chemist and I teach O-Chem, which frequently uses dry solvents, like anhydrous acetone.
But PERC, the chemical used in “dry cleaning” is NOT a dry liquid, so the existence of dry liquids is also not relevant to their example.
I can’t figure out if the confusion is caused by unfamiliarity with the term dry cleaning, or just a feeble grasp of logic.
