Identify the error in the sentence: The radio broadcast has heard by almost everyone in the country.

The sentence "The radio broadcast has heard by almost everyone in the country" contains a grammatical error related to the form of the verb. The phrase "has heard" is not correctly used here because it does not align with the intended passive construction of the sentence.

In passive voice constructions, the subject receives the action rather than performing it. Therefore, the correct form should be "has been heard." This indicates that the radio broadcast is the subject that has experienced the action of being heard by the audience. The proper structure would change the verb to a passive form, utilizing "been" to maintain agreement with the subject.

Thus, the correct response focuses on adjusting the verb to reflect this passive relationship, allowing the sentence to communicate that the broadcast has been heard by the listeners throughout the country. This small adjustment clarifies the meaning and ensures grammatical accuracy in the sentence.
