Passage: In the early 1970s, ABC completed its transition to color; the decade as a whole would mark a turning point for ABC, as it began to pass CBS and NBC in the ratings to become the first place network. It also began to use behavioral and demographic data to better determine what types of sponsors to sell advertising slots to and provide programming that would appeal towards certain audiences. ABC's gains in audience share were greatly helped by the fact that several smaller markets had grown large enough to allow full-time affiliations from all three networks. Question: What kind of data did ABC begin using in the 1970s to better target ads and programming for certain audiences?

Passage: Disorders of the immune system can result in autoimmune diseases, inflammatory diseases and cancer. Immunodeficiency occurs when the immune system is less active than normal, resulting in recurring and life-threatening infections. In humans, immunodeficiency can either be the result of a genetic disease such as severe combined immunodeficiency, acquired conditions such as HIV/AIDS, or the use of immunosuppressive medication. In contrast, autoimmunity results from a hyperactive immune system attacking normal tissues as if they were foreign organisms. Common autoimmune diseases include Hashimoto's thyroiditis, rheumatoid arthritis, diabetes mellitus type 1, and systemic lupus erythematosus. Immunology covers the study of all aspects of the immune system. Question: What acquired condition results in immunodeficiency in humans?
HIV/AIDS
