I want to know the answer to the following question:
What is the lowest elevation in the British Isles?
All the background I'm provided with is that "The islands are at relatively low altitudes, with central Ireland and southern Great Britain particularly low lying: the lowest point in the islands is Holme, Cambridgeshire at −2.75 m (−9.02 ft).". Is that enough to answer the question?
Answer: yes
