The scientists are working to find a cure
Answer:
The correct answers are answers C, D and E.
Explanation:
Simple sentences contain only one subject and one predicate. On the other hand, compound sentences contain more than one subject and more than one predicate. In other words, compound sentences are formed by two or more simple sentences.
If you can separate the sentence in two (or more) and both parts still make sense, and each one has a subject and a predicate, then we're saying this original sentence is a compound sentence.
In sentence C we have two subjects: Informational messages and sensitive messages. Each one has his predicate.
In sentence D we have two subjects: Good writers and bad writes. Each one has his predicate.
In sentence E we have two subjects: Pie charts and bar charts. Each one has his predicate.
