Answer 1

Her birthday would be celebrated in a grand manner tommorow.

Answer 2

Passive Voice is a sentence in which the subject undergoes the action of the verb, or in simple words, writing the sentence in reverse order.

Active Voice is a sentence in which the subject is performing the action.

Let us understand this using an example:

He shot the lion. (Active Voice)

The lion was shot by him. (Passive Voice)

Notice the difference. (Try applying the meaning of active and passive voice to understand it better)

She will celebrate her birthday tomorrow in a grand manner. (Active)

Her birthday will be celebrated in a grand manner tomorrow. (Passive)

Hope it helps :)
