[Which sentence is grammatical? Can we use both sentences? What is the difference?]
2 is correct because the two verbs' actions don't take place at the same time. The pots were broken before the master came home; therefore, 2 is correct.
3 is correct because the two verbs' actions don't take place at the same time. The pizza was eaten before "he was upset."
Both sentences are grammatically correct, but they have slightly different meanings.
Sentence 1, "He was angry because the dog broke the flowerpots," describes a specific event that occurred in the past. It suggests that the master became angry immediately after discovering that the dog broke the flowerpots.
Sentence 2, "He was angry because the dog had broken the flowerpots," uses the past perfect tense. It implies that the dog broke the flowerpots before the master arrived home. This sentence indicates that the anger occurred after the master saw the mess caused by the dog.
So, in summary, sentence 1 emphasizes the immediate cause of the anger (the dog breaking the flowerpots), while sentence 2 emphasizes the chronological order of events (the dog breaking the flowerpots first, and then the master becoming angry after seeing the mess). Both sentences can be correct, depending on the specific situation and the intended meaning.
