All of the above.', 'role': 'user'}, {'content': 'Answer: D \nExplanation: The chief oral manifestations of scarlet fever have been\xa0referred to as stomatitis scarlatina.\xa0\nSmall punctate red\xa0macules may appear on the hard and\xa0soft palate and uvula. These are called Forchheimer spots;\xa0however, these are not diagnostic since they may be present\xa0in other infectious conditions like rubella, roseola, infectious\xa0mononucleosis, and septicemia.\nThe palate and the throat are\xa0often fiery red. The tonsils and faucial pillars are usually\xa0swollen and sometimes covered with a grayish exudate. More important are the changes occurring in the tongue. Early\xa0in the course of the disease, the tongue exhibits a white\xa0coating and the fungiform papillae are edematous and\xa0hyperemic, projecting above the surface as small red knobs.\xa0This phenomenon has been described clinically as ‘strawberry\xa0tongue’.\xa0\nThe coating of the tongue is soon lost; beginning at\xa0the tip and lateral margins, and this organ becomes deep red,\xa0glistening and smooth except for the swollen, hyperemic\xa0papillae. The tongue in this phase has been termed as the\xa0‘raspberry tongue’.', 'role': 'assistant'}]
