To identify which sentence includes a dependent clause, we need to understand the difference between a dependent clause and an independent clause.

A dependent clause is a group of words that contains a subject and a verb but does not express a complete thought. It relies on an independent clause to form a complete sentence. On the other hand, an independent clause expresses a complete thought and can stand alone as a sentence.

Let's break down each sentence to determine which one contains a dependent clause:

1. When looking out the window, they saw the first leaf fall.
- This sentence includes a dependent clause. "When looking out the window" is the dependent clause because it starts with the subordinating conjunction "when" and cannot stand alone as a complete sentence. It relies on the independent clause "they saw the first leaf fall" to complete the thought.

2. The boy received a dog named Rover for his birthday.
- This sentence does not have a dependent clause. It contains one independent clause ("The boy received a dog named Rover for his birthday"), which expresses a complete thought.

3. On the way to the store, Nicole saw a lost cat.
- This sentence does not have a dependent clause. It also contains one independent clause ("Nicole saw a lost cat"), which expresses a complete thought.

4. They gave sandwiches to the children on paper plates.
- This sentence does not have a dependent clause. It consists of one independent clause ("They gave sandwiches to the children on paper plates"), which expresses a complete thought.

So, the sentence that includes a dependent clause is: "When looking out the window, they saw the first leaf fall."
