There was great public interest when a big hole mysteriously appeared in the middle of a field. Army mechanics and engineers were called in to explain how it had got there. They orrered various explanations but were not at all sure how the hole had’been caused. It was thought that a large shell which must have lain buried under the ground for many years had suddenly exploded, but it was not possible to prove this.
A “simple", but highly improbable, explanation was offered by a man who claims to be especially well-informed about "flying saucers —the strange objects which are round in shape and are said to visit the earth occasionally from outer space. The man’s explanation may have been nonsense, but at least it was imaginative. At any rate, it was far more interesting than the one given by the army.
After examing the ground carefully, the man claimed to have seen special marks on the soil quite near the hole.

B. not capable of proof
