Concept:In reported speech, a direct command or order is changed to an infinitive phrase, and the reporting verb often shifts to a stronger verb like “ordered” to show the tone.
Explanation:The given sentence is an imperative command: “Be quiet and listen carefully.”
First, remove the quotation marks and change the imperative verbs to an infinitive: “to be quiet and listen carefully.” Note that the second verb “listen” remains in base form after “to be quiet and” because it is part of the same infinitive structure.
Next, choose a reporting verb that matches the tone. “Said” is neutral; here the tone is a direct order, so use “ordered.” The listener is indirectly referred to as “them” (implied audience).
Thus, the correct indirect speech becomes: “The man ordered them to be quiet and listen carefully.”
Other options are incorrect: Option A uses “said” which lacks the commanding tone; Option C uses “asked” (request, not order); Option D changes the meaning to a suggestion (“advised”) and omits “listen carefully.”
Answer:Option B – The man ordered them to be quiet and listen carefully.
