Which of these adjectives best describes the young man in this reading passage?
The applicant, by this time, stood within the doorway. Coming freshly, as he did, out of the morning light, he appeared to have brought some of its cheery influences into the shop along with him. It was a slender young man, not more than one or two and twenty years old, with rather a grave and thoughtful expression for his years, but likewise a springy alacrity and vigor. These qualities were not only perceptible, physically, in his make and motions, but made themselves felt almost immediately in his character. A brown beard, not too silken in its texture, fringed his chin, but as yet without completely hiding it; he wore a short mustache, too, and his dark, high-featured countenance looked all the better for these natural ornaments. As for his dress, it was of the simplest kind; a summer sack of cheap and ordinary material, thin checkered pantaloons, and a straw hat, by no means of the finest braid. Oak Hall might have supplied his entire equipment. He was chiefly marked as a gentleman--if such, indeed, he made any claim to be--by the rather remarkable whiteness and nicety of his clean linen.
