I want to know the answer to the following question:
What year did Frédéric leave Warsaw after moving with his family to the south annex of Krasiński Palace?
All the background I'm provided with is that "In 1827, soon after the death of Chopin's youngest sister Emilia, the family moved from the Warsaw University building, adjacent to the Kazimierz Palace, to lodgings just across the street from the university, in the south annex of the Krasiński Palace on Krakowskie Przedmieście,[n 5] where Chopin lived until he left Warsaw in 1830.[n 6]". Is that enough to answer the question?
Answer: yes
