Answer:
Determiner.
Explanation:
Determiners are words, most times pronouns placed before a noun, that qualifies/determines something about the noun placed after it or shows who possess it.
Pronouns (possessive) on the other hand do not require a noun after it.
Examples of determiners: the, this, some, your, my, enough, their, etc
Examples below:
- The teacher left <em>some books</em> on the shelf. Vs You can pick <em>some</em> later if you are interested.
(In the first sentence <em>some books</em> is explicit in qualifying the number of books while in the second sentence the word <em>some</em> replaces books)
- The closing deadline for the project is quite close. Have you completed yours?
( <em>The</em> placed before <em>project</em> determines that we are talking about the project while, <em>yours</em> is the possessive pronoun that replaces your project).
Therefore, These bagels are stale. These determines which bagels are stale followed by the word Bagels, a noun.
