Answer:
A storage bin was once blown up because of carlessness.
Step-by-step explanation:
Passive voice puts an object that experiences the action and that is acted upon as the center of the sentence. In the active sentences, someone or something is performing an action on the object or person. Therefore, in the passive sentence, the object becomes the subject of the sentence.
An active sentence could say Someone blew up the storage bin because of the carelessness – in this example, a storage bin is an object, while someone is the subject.
However, in the given example, a storage bin becomes the center of the sentence – it is being acted upon by being blown up.
Passive voice is also recognizable by the usage of the verb to be in the correct tense + the past participle. In the sentence, we have was, the past tense of the verb to be + blown up, which is the past participle of the verb to blow.
