{'answer_start': array([42]), 'answer_text': array(['five months'], dtype=object)}
The Republic of Formosa survived for only five months.  The Japanese landed near Keelung on the northern coast of Taiwan on 29 May 1895, and in a five-month campaign swept southwards to Tainan.  During the night of 4 June, on the news that the Japanese had captured Keelung, President T'ang and General Chiu fled to Tamsui, and from there sailed for the mainland on the evening of 6 June.  The Japanese entered Taipei shortly afterwards.[10]
