Assume there are multiple books on a shelf. At least one book is red. At least one book is blue.
Sentence in dispute:
Some of the books are red.
Is this sentence false if only one book is red?
A non-native English speaker says this sentence must be false because the verb is plural (“are”), and so it is true only if there are at least two red books.
But a native speaker of English says that the sentence is true.
Which view is correct?
