Final answer:
The sentence in question is in the passive voice as Octavius, the subject, is receiving the action of being given applause by the audience.
Step-by-step explanation:
The question "Was Octavius given a huge hand by the audience after the recital?" is in the passive voice. The passive voice is a grammatical construction where the typical object of the sentence becomes the subject and is acted upon by an agent. In this case, Octavius is receiving the action rather than performing it, suggesting that the audience (the agent) is giving the applause.
In contrast, an active voice construction of the same idea would be "Did the audience give Octavius a huge hand after the recital?" Here, the audience is the subject performing the action of giving applause directly.
