Combine these simple sentences using parallel structure. the convict tried to plead with the guards. the convict shouted at the guards. the convict ended by threatening the guards.

The convict tried to plead with the guards, but he shouted at them and ended by threatening them.

Explanation:

Parallelism occurs when a text contains the same grammatical structure. In the example given, the three sentences are written in the Past Simple tense and indicate a series of finished actions in the past. As a consequence, they can be combined by adding the coordinating conjunction but to introduce a contrast, using pronouns to avoid repetition, and leaving the three main verbs in the Past Simple tense: tried, shouted and ended.
