Input: Consider Input: Paragraph- Sent 1: At length, as I entered the pass, the huge rocks began to close around in all their wild, mysterious impressiveness, when suddenly, as I was gazing eagerly about me, a drove of gray hairy beings came in sight, lumbering toward me with a kind of boneless, wallowing motion like bears.
Sent 2: I never turn back, though often so inclined, and in this particular instance, amid such surroundings, everything seemed singularly unfavorable for the calm acceptance of so grim a company.
Sent 3: Suppressing my fears, I soon discovered that although as hairy as bears and as crooked as summit pines, the strange creatures were sufficiently erect to belong to our own species.
Sent 4: They proved to be nothing more formidable than Mono Indians dressed in the skins of sage-rabbits.
Sent 5: Both the men and the women begged persistently for whisky and tobacco, and seemed so accustomed to denials that I found it impossible to convince them that I had none to give.

Question: Which two products were the mono Indians able to name?.
Output: Whisky and tobacco.
