Ques: Their Eyes Were Watching God is a 1937 novel and the best known work by African-American writer Zora Neale Hurston. The novel narrates main character Janie Crawford's "ripening from a vibrant, but voiceless, teenage girl into a woman with her finger on the trigger of her own destiny." As a young woman, who is fair-skinned with long hair, she expects more out of life, but comes to realize she has to find out about life' fuh theyselves' (for herself), just as people can only go-to-God for themselves. Set in central and southern Florida in the early 20th century, the novel was initially poorly received for its rejection of racial uplift literary prescriptions.

Ques: Context: Springfield's original name was Calhoun, after Senator John C. Calhoun of South Carolina. The land that Springfield now occupies was originally settled by trappers and traders who came to the Sangamon River in 1818. The settlement's first cabin was built in 1820, by John Kelly. It was located at what is now the northwest corner of Second Street and Jefferson Street. In 1821, Calhoun became the county seat of Sangamon County due to fertile soil and trading opportunities. Settlers from Kentucky, Virginia, and as far as North Carolina came to the city. By 1832, Senator Calhoun had fallen out of the favor with the public and the town renamed itself Springfield after Springfield, Massachusetts. At that time, Springfield, Massachusetts was comparable to modern-day Silicon Valley -- known for industrial innovation, concentrated prosperity, and the celebrated Springfield Armory. Most importantly, it was a city that had built itself up from frontier outpost to national power through ingenuity -- an example that the newly named Springfield, Illinois, sought to emulate. Kaskaskia was the first capital of the Illinois Territory from its organization in 1809, continuing through statehood in 1818, and through the first year as a state in 1819. Vandalia was the second state capital of Illinois from 1819 to 1839. Springfield became the third and current capital of Illinois in 1839. The designation was largely due to the efforts of Abraham Lincoln and his associates; nicknamed the "Long Nine" for their combined height of 54 feet (16 m).

RBV proposed that firms are heterogenous because they possess heterogenous resources.
