The sentence "She smiled as she opened the package." includes a dependent clause.

To determine which sentence includes a dependent clause, we need to understand what a dependent clause is. A dependent clause is a group of words that contains both a subject and a verb but cannot stand alone as a complete sentence because it does not express a complete thought.

In the given sentences:

1. "It was a fancy hat!" - This sentence does not include a dependent clause because it consists of a subject "It" and a verb "was," which express a complete thought.

2. "The package was heavy." - This sentence does not include a dependent clause either as it also consists of a subject "The package" and a verb "was" that form a complete thought.

3. "She smiled as she opened the package." - This sentence includes a dependent clause. The dependent clause in this sentence is "as she opened the package." It has a subject "she" and a verb "opened," but it cannot stand alone as a complete sentence because it does not express a complete thought.

4. "Today is her 16th birthday." - This sentence does not include a dependent clause since it consists of a subject "Today" and a verb "is" that form a complete thought.

Therefore, the sentence that includes a dependent clause is: "She smiled as she opened the package."
