true; those in the basket are good apples.

demonstrative force as the pronoun, but is followed by a noun.

equivalent to who or which, serving to point out, and make definite, a
person or thing spoken of, or alluded to, before, and may be either
singular or plural.

its force as a demonstrative pronoun.

object of the preceding verb, or as the subject or predicate nominative
of a verb.
