Answer:
The writer combined two independent clauses into one sentence by joining them with the transitional word because.
Step-by-step explanation:
In this example, the original sentences are independent. We learn this for various reasons. The two sentences are separated by a period. Moreover, both sentences have a subject, a verb and a predicate. Finally, both sentences express a full idea. When the sentences are joined, we see that the new sentence is logical and well-structured because of the transitional word "because."
