Read the text and answer the question.

Lena had been losing sleep for weeks because of heavy footsteps and furniture scraping from the apartment above hers, often after 11 p.m. She left a polite note for her upstairs neighbour, but the noise continued, so she contacted the building manager. The manager reviewed the lease, which restricts loud activity between 10 p.m. and 8 a.m., and spoke directly with the neighbour. The neighbour agreed to add rugs to the floor and to move furniture only during the day. The manager told Lena to report back if the noise did not improve within two weeks.
