Instructions: In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
Input: Who did the white men refrain from threatening, African-Americans or their landlords?, Context: Black labor played a crucial role in Miami's early development. During the beginning of the 20th century, migrants from the Bahamas and African-Americans constituted 40 percent of the city's population. Whatever their role in the city's growth, their community's growth was limited to a small space. When landlords began to rent homes to African-Americans in neighborhoods close to Avenue J (what would later become NW Fifth Avenue), a gang of white man with torches visited the renting families and warned them to move or be bombed.
Output:
landlords
