Juan, who is my best friend, joined the marching band in ninth grade.

The sentence that includes a dependent clause is: "Juan, who is my best friend, joined the marching band in ninth grade."

To identify which sentence includes a dependent clause, we need to understand the characteristics of a dependent clause. A dependent clause is a group of words that contains a subject and a verb but cannot stand alone as a complete sentence. It relies on an independent clause to complete its meaning.

Let's analyze each sentence:

1. "Juan, who is my best friend, joined the marching band in ninth grade." - This sentence includes a dependent clause ("who is my best friend") that cannot stand on its own and relies on the independent clause ("Juan joined the marching band in ninth grade") to complete its meaning.

2. "After school, the band practices in the school parking lot." - This sentence does not include a dependent clause as it is a complete sentence on its own.

3. "The band director lets them take frequent breaks." - This sentence does not include a dependent clause as it is a complete sentence on its own.

4. "The band is going to play the song 'Thriller' this Halloween weekend." - This sentence does not include a dependent clause as it is a complete sentence on its own.

Therefore, the sentence that includes a dependent clause is: "Juan, who is my best friend, joined the marching band in ninth grade."
