I want to know the answer to the following question:
When was Warrington added to Lancashire?
All the background I'm provided with is that "To the existing county boroughs of Barrow-in-Furness, Blackburn, Bolton, Bootle, Burnley, Bury, Liverpool, Manchester, Oldham, Preston, Rochdale, Salford, St Helens and Wigan were added Blackpool (1904), Southport (1905), and Warrington (1900).". Is that enough to answer the question?
Answer: yes
