Sent 3: The dusky litter of the cabin set off her radiant trimness: tarry Johnson was a foil to her fair beauty; she glowed in that poor place, fair as a star; until even I, who was not usually of her admirers, caught a spark of admiration; and even the captain, who was in no courtly humour, proposed that the scene should be commemorated by my pencil.

Sent 5: Hurriedly as I went about my task, the half-hour had lengthened out to more than three before it was completed: Mamie in full value, the rest of the party figuring in outline only, and the artist himself introduced in a back view, which was pronounced a likeness.

Question: Did the speaker devote their attention to the character in a plush Gainsborough hat? (A) No (B) Yes.
