What action did Sue take regarding her house this summer?

The choice indicating that Sue had her house done up is particularly insightful because it suggests that she made improvements or renovations to her existing home rather than disposing of it or purchasing a different one. This option reflects a proactive approach to enhancing her living space, emphasizing maintenance and aesthetic improvement.

In contrast, the other options imply either the sale or purchase of property, which would denote significant changes in her residence status. Choosing to renovate or update a house, as suggested by having it done up, often aligns with personal investment in a property, which can indicate a commitment to where one lives rather than a desire to move on or detach from it. This action reflects common homeowner behavior during summer, a traditional season for renovations and home improvements due to favorable weather conditions.
