The Passage said Something Like, it takes one day or more to tramp. And in this case though they didn't use the word minimum, but from logic inference that is the implication
As in the passage it is no where mentioned that minimum time for tramping is 1 day neither in the passage it was declined so answer should be not given as per my understadning. If anywhere in the passage it was that Min time for tramping is not 1 day then in that case it should be false. confirmation for min. 1 day is also not present so for me it should be Not given.
