Final answer:
The sentence "Jayden is using correct capitalization and punctuation in his paper" is a simple sentence, as it contains only one main clause. To contrast, Mateo's messages demonstrate the use of different sentence structures depending on context, which can shift from simple to compound-complex depending on the combination of clauses.
Step-by-step explanation:
- When considering the sentence "Jayden is using correct capitalization and punctuation in his paper," it is identified as a simple sentence. A simple sentence consists of only one main clause and expresses a complete thought. It does not contain any subordinate clauses or additional main clauses. In contrast, a compound sentence contains at least two independent clauses joined by a conjunction, a semicolon, or a conjunction adverb.
- A complex sentence includes one independent clause and at least one dependent clause, which cannot stand alone as a complete sentence. Lastly, a compound-complex sentence features at least two independent clauses and one or more dependent clauses.
- In the context provided, Mateo's changing usage of capitalization and punctuation demonstrates how these elements can modify the tone and formality of written communication. If Mateo were to combine his casual and formal messages into one sentence using proper conjunctions and subordinating words, he could potentially create a compound-complex sentence.
- For example, a compound-complex sentence might look like this: "While Mateo often used casual language in texts, his formal emails contain proper punctuation, and they adhere to grammatical norms."
