Educational worksheet on sentence types featuring blue whale facts.

Let's solve this step-by-step. The task is to identify the type of sentence for each of the 15 sentences listed. There are four kinds of sentences:

1. Declarative – makes a statement or gives information (ends with a period).
2. Interrogative – asks a question (ends with a question mark).
3. Imperative – gives a command or request (often ends with a period, but can end with an exclamation mark).
4. Exclamatory – expresses strong emotion or surprise (ends with an exclamation mark).

Now let’s go through each sentence:

---

1. The blue whale is the largest animal.
→ This is a statement giving information.
✔ Declarative

2. It is bigger than thirty elephants.
→ A statement of fact.
✔ Declarative

3. How much does it eat every day?
