Answer :
To identify the sentence type "You should look your best when you go on a date," we need to understand the structure of the sentence.
1. Simple Sentence: A simple sentence contains a subject and a verb and expresses a complete thought. It consists of a single independent clause.
Example: "She sings beautifully."
2. Compound Sentence: A compound sentence contains two independent clauses joined by a coordinating conjunction (for, and, nor, but, or, yet, so) or a semicolon.
Example: "He wanted to go to the park, but she preferred staying home."
3. Complex Sentence: A complex sentence contains one independent clause and at least one dependent clause. The dependent clause cannot stand alone as a complete sentence.
Example: "Although he studied hard, he couldn't pass the exam."
4. Compound-Complex Sentence: A compound-complex sentence has two or more independent clauses and at least one dependent clause.
Example: "She enjoys playing the piano, but she has to practice every day because she has a recital coming up."
In the sentence "You should look your best when you go on a date," we have one independent clause ("You should look your best") and no dependent clause. Therefore, the sentence type is **Simple**.
