Question

What can the reader Infer about the speakers views on marriage?

Answer 1

In this passage, almost nothing. I suppose because at 41 he was hale and healthy until he took a job on a railway babysitting a box of guns on a 200 mile rail journey, he lost his health. But to conclude much more is a travesty and the answer should not be anything.

So you should probably choose B. He is hale and hardy because (it is inferred ) he has avoided marriage.
