Correct Answer: renovate

Solution : The correct choice is the fourth option .

Renovate means to repair and improve a building, making it look new again, which fits well in the context of the sentence.

The meanings of other options are as follows:

• Astonish : This means to surprise or amaze someone greatly. This doesn't fit the context of doing something to a house.
• Console : This means to comfort someone at a time of grief or disappointment. Again, this doesn't align with the context of working on a house.
• Bleat : This is the sound made by a sheep or goat, or to speak in a weak or complaining way.

Therefore, the complete sentence is: It’s not possible to renovate this house in this amount.
