Answer 1

the house has been designed by them for an hour

Answer 2

Passive voice

A house has been designed for an hour by them.

Explanation:

• In English Language there are two narrative voices- the active voice and the passive.
• In the active voice the subject of a sentence is followed by the action verb.
• The action is performed directly by the subject. The action passes on to the receiver of the action-the object.
• In the passive voice the object takes the position of the subject and is worked upon by the passive verb.
• The verb takes the past participle form preceded by an auxiliary verb which specifies the tense of the sentence.
• The given sentence, 'they have designed a house for an hour', is in the active voice.
• The subject of the sentence is 'they'.
• The verb 'have designed' is in the present perfect tense.
• The passive form of the sentence will thus be: A house has been designed for an hour by them.
