Evaluate the usefulness of the following entry on a note card for a speech about orphans in South Africa due, in large measure, to the AIDS epidemic there. Time (3 Dec. 2012)

recently reported that "3.37 million South African children under 17 [have lost] one or both parents, according to a 2011 census." The article also notes that "Antiretroviral drugs weren't available until 2004 and were difficult to obtain for many years after that." Grandmothers who are raising their orphaned grandchildren find it "challenging" when they try to talk with their grandchildren and warn them about HIV. "I don't have the right words," one 81 year old woman confided, adding, "My granddaughter laughs at me when I try." A) The card contains useful information, and a good blend of statistics, facts, and testimony. B) The statistical information and factual information are strong, but the testimony should be cut since AIDS is nothing to laugh about. C) The card contains good statistical information and testimony, but the specific types of drugs remain unidentified. D) The card contains information for three separate ideas, which defeats the purpose of using cards.
