Ex Input:
proper question: Is the weather of southern Europe survivable for fleas? 
 disfluent question: Is the weather of southern Europe survivable for rats er fleas? 
 context: In addition to arguing that the rat population was insufficient to account for a bubonic plague pandemic, sceptics of the bubonic plague theory point out that the symptoms of the Black Death are not unique (and arguably in some accounts may differ from bubonic plague); that transference via fleas in goods was likely to be of marginal significance; and that the DNA results may be flawed and might not have been repeated elsewhere, despite extensive samples from other mass graves. Other arguments include the lack of accounts of the death of rats before outbreaks of plague between the 14th and 17th centuries; temperatures that are too cold in northern Europe for the survival of fleas; that, despite primitive transport systems, the spread of the Black Death was much faster than that of modern bubonic plague; that mortality rates of the Black Death appear to be very high; that, while modern bubonic plague is largely endemic as a rural disease, the Black Death indiscriminately struck urban and rural areas; and that the pattern of the Black Death, with major outbreaks in the same areas separated by 5 to 15 years, differs from modern bubonic plague—which often becomes endemic for decades with annual flare-ups.

proper question: Who led the attack on Spain in 1565? 
 disfluent question: Who led the attack on Spain in 1964 or uh wait 1565? 
 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, René Goulaine de Laudonnière established the first European settlement, Fort Caroline, on the St. Johns near the main village of the Saturiwa. Philip II of Spain ordered Pedro Menéndez de Avilés 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.
