Introduction:
In this question, we are asked to select the suitable demonstrative pronoun for the sentence "Who is ______ banging loudly at the door?". Demonstrative pronouns are used to point out specific people, things, or groups. They include words like "this", "that", "these", and "those".
Detailed
To select the suitable demonstrative pronoun, we need to consider the context of the sentence. Let's analyze the options:
1. this: "this" is a singular pronoun that refers to something close to the speaker. In this sentence, the speaker is asking about someone banging loudly at the door, which implies that the person is not close to the speaker. Therefore, "this" is not the suitable pronoun.
2. those: "those" is a plural pronoun that refers to something far from the speaker and the listener. In this sentence, we are not referring to multiple people or things, but rather a singular person banging at the door. Therefore, "those" is not the suitable pronoun.
3. that: "that" is a singular pronoun that refers to something far from both the speaker and the listener. In this sentence, the person banging at the door is not close to the speaker or the listener. Therefore, "that" is the suitable pronoun.
4. these: "these" is a plural pronoun that refers to something close to both the speaker and the listener. In this sentence, we are not referring to multiple people or things, but rather a singular person banging at the door. Therefore, "these" is not the suitable pronoun.
Answer:
The suitable demonstrative pronoun for the sentence "Who is ______ banging loudly at the door?" is that.
