On my old Upper-Intermediate Book it's reported that whole plus a plural noun ( for instance whole businesses) means each one.
To be more clear, I write here the explanation the book gives:
"It's possible to say WHole businesses are affected....without the definite article, but this refears to each individual business"
So, my question is: "Does it mean each business?" Surfing on the Internet, I saw it is generally explained that it means "entire businesses", meaning many of them but not all of them.
Might you explain it to me?
