Given the task definition, example input & output, solve the new input case.
Use a disfluent question or a proper question and find the answer to the question based on the given context or return None if an answer can't be found. A disfluent question is a question that has some interruptions in it while framing. A proper question is the correct form of the question without any disfluency.
Example: proper question: In what year did the U of C become one of 7 founding members of the Association of Chicago Universities?
disfluent question: In what year did Robert Harper or did the U of C become one of 7 founding members of the Association of Chicago Universities?
context: Founded by the American Baptist Education Society with a donation from oil magnate and wealthiest man in history John D. Rockefeller, the University of Chicago was incorporated in 1890; William Rainey Harper became the university's first president in 1891, and the first classes were held in 1892. Both Harper and future president Robert Maynard Hutchins advocated for Chicago's curriculum to be based upon theoretical and perennial issues rather than on applied sciences and commercial utility. With Harper's vision in mind, the University of Chicago also became one of the 14 founding members of the Association of American Universities, an international organization of leading research universities, in 1900.
Output: None
The answer to the above question is not found from the context hence it is not answerable so the output is 'None' so it is a positive example.

New input case for you: proper question: Where did Ribault erect the flag claiming the land for France?
disfluent question: When did no wait Where did Ribault erect the flag claiming the land for France?
context: French Huguenot explorer Jean Ribault charted the St. Johns River in 1562 calling it the River of May because he discovered it in May. Ribault erected a stone column near present-day Jacksonville claiming the newly discovered land for France. In 1564, Rene Goulaine de Laudonniere established the first European settlement, Fort Caroline, on the St. Johns near the main village of the Saturiwa. Philip II of Spain ordered Pedro Menendez de Aviles to protect the interest of Spain by attacking the French presence at Fort Caroline. On September 20, 1565, a Spanish force from the nearby Spanish settlement of St. Augustine attacked Fort Caroline, and killed nearly all the French soldiers defending it. The Spanish renamed the fort San Mateo, and following the ejection of the French, St. Augustine's position as the most important settlement in Florida was solidified. The location of Fort Caroline is subject to debate but a reconstruction of the fort was established on the St. Johns River in 1964.
Output:
None
