Which is correct? You should never believe ( these kind, these kinds ) of stories.

Think the correct answer is ( these kinds)

Look at the noun.

kind = singular = this kind
kinds = plural = these kinds

Sra (aka Mme)

Right.

You are correct! The correct phrase to use in this sentence is "these kinds."

To determine which form of the word "kind" to use, we need to consider the noun it is modifying. In this sentence, "kind" is modifying the plural noun "stories." Since "stories" is plural, we need to use the plural form of the adjective "kind," which is "kinds."

To clarify, when modifying a plural noun, we often add an "s" to the adjective to make it plural as well. In this case, "kind" becomes "kinds" to match the plural noun "stories."
