The answer is B) by describing the trip as a pilgrim
It is simply saying that all is now in chaos. I am assuming the part that is confusing is "the quiet sands have run." It could easily be alluding to the way that during a sandstorm, the calm sands of the surface are no longer there as the chaos of the storm casts them about.
Inflecting run to running changes the word would into a {ANSWER adverb} hope this helpds :*)
The participle is "digging." Most participles end in -ing. It modifies "man", describing what the man is doing.
