Problem: The origin of Tom Robinson is less clear, although many have speculated that his character was inspired by several models. When Lee was 10 years old, a white woman near Monroeville accused a black man named Walter Lett of raping her. The story and the trial were covered by her father's newspaper which reported that Lett was convicted and sentenced to death. After a series of letters appeared claiming Lett had been falsely accused, his sentence was commuted to life in prison. He died there of tuberculosis in 1937. Scholars believe that Robinson's difficulties reflect the notorious case of the Scottsboro Boys, in which nine black men were convicted of raping two white women on negligible evidence. However, in 2005, Lee stated that she had in mind something less sensational, although the Scottsboro case served "the same purpose" to display Southern prejudices. Emmett Till, a black teenager who was murdered for flirting with a white woman in Mississippi in 1955, and whose death is credited as a catalyst for the Civil Rights Movement, is also considered a model for Tom Robinson.
Emmett Till's death sparked which political movement in the '50s?

Problem: On 16 March 1934, President Franklin D. Roosevelt signed the Migratory Bird Hunting Stamp Act, which requires an annual stamp purchase by all hunters over the age of sixteen. The stamps are created on behalf of the program by the US Postal Service and depict wildlife artwork chosen through an annual contest. They play an important role in habitat conservation because ninety-eight percent of all funds generated by their sale go directly toward the purchase or lease of wetland habitat for protection in the National Wildlife Refuge System.[citation needed] In addition to waterfowl, it is estimated that one third of the nation's endangered species seek food and shelter in areas protected using Duck Stamp funds.[citation needed]
What does the Act require all hunters over the age of sixteen to do?

Answer:
an annual stamp purchase
