Some dentist have clean teeth

answer: declarative

Yes, 3 is declarative.

To determine the type of each sentence, we need to understand the function and structure of different sentence types.

1. "God exists." This sentence is an example of an exclamatory sentence because it expresses strong emotion or surprise. However, it should be noted that in this specific example, the sentence lacks an exclamation mark, which would typically be used to indicate exclamatory intent. Without this punctuation, it might also be interpreted as a declarative statement.

2. "What are you up to?" This sentence is an interrogative sentence because it asks a question. Interrogative sentences typically start with question words like "what," "where," "why," "when," "who," or "how."

3. "Some dentists have clean teeth." This sentence is an example of a declarative sentence because it makes a statement or provides information. Declarative sentences usually end with a period and state a fact or opinion.

It's important to remember that punctuation and context play a role in determining the type of sentence. While the answer provided above is based on the structure of the sentence, additional factors such as intonation, emphasis, and overall context can affect the interpretation.
