Answer: B. malnutrition
Step-by-step explanation:
The Great Depression (1929) pushed many middle-class families into poverty, which explains the rising malnutrition among children during the 1930s. The economic crisis trumped the previous general improvement in children´s lives. One of the first New Deal relief programs was aimed to provide emergency food relief and school lunch programs, base on the recommendations of the U.S. Children's Bureau's Child Health Recovery Conference (1933).
