Final answer:
The duration of Mr. Terupt's surgery in the book 'Because of Mr. Terupt' is not given. Instead, a passage describes a scenario of a different doctor working under wartime conditions, operating for up to sixty hours without breaks, which is not directly related to Mr. Terupt's surgery.
Step-by-step explanation:
In the book Because of Mr. Terupt, the specific duration of Mr. Terupt's surgery is not explicitly mentioned. However, the passage provided describes a Dr. Edward, who operated for as long as sixty hours at a stretch, but this seems to be from a different context and not related to the story of Mr. Terupt. It may be referencing wartime conditions and a different situation in which a doctor had to perform surgeries under extreme conditions, without sleep or rest, while facing the dangers of bombs and shells around the hospital. In this passage, Dr. Edward's dedication in such a grueling environment is highlighted.
