Example Input: Around 2.5 million years ago (ending 11,600 years ago) was the geological period of the Ice Ages. Since approximately 600,000 years ago, six major Ice Ages have occurred, in which sea level dropped 120 m (390 ft) and much of the continental margins became exposed. In the Early Pleistocene, the Rhine followed a course to the northwest, through the present North Sea. During the so-called Anglian glaciation (~450,000 yr BP, marine oxygen isotope stage 12), the northern part of the present North Sea was blocked by the ice and a large lake developed, that overflowed through the English Channel. This caused the Rhine's course to be diverted through the English Channel. Since then, during glacial times, the river mouth was located offshore of Brest, France and rivers, like the Thames and the Seine, became tributaries to the Rhine. During interglacials, when sea level rose to approximately the present level, the Rhine built deltas, in what is now the Netherlands.
Example Output: What period was 2.5 million years ago?

Example Input: Interracial relations between Indigenous Americans and African Americans is a part of American history that has been neglected. The earliest record of African and Indigenous American relations in the Americas occurred in April 1502, when the first Africans kidnapped were brought to Hispaniola to serve as slaves. Some escaped, and somewhere inland on Santo Domingo, the first Black Indians were born. In addition, an example of African slaves' escaping from European colonists and being absorbed by Indigenous Americans occurred as far back as 1526. In June of that year, Lucas Vasquez de Ayllon established a Spanish colony near the mouth of the Pee Dee River in what is now eastern South Carolina. The Spanish settlement was named San Miguel de Gualdape. Amongst the settlement were 100 enslaved Africans. In 1526, the first African slaves fled the colony and took refuge with local Indigenous Americans.
Example Output: What is considered to be neglected in American history?

Example Input: The rival of Takeda Shingen (1521–1573) was Uesugi Kenshin (1530–1578), a legendary Sengoku warlord well-versed in the Chinese military classics and who advocated the "way of the warrior as death". Japanese historian Daisetz Teitaro Suzuki describes Uesugi's beliefs as: "Those who are reluctant to give up their lives and embrace death are not true warriors.... Go to the battlefield firmly confident of victory, and you will come home with no wounds whatever. Engage in combat fully determined to die and you will be alive; wish to survive in the battle and you will surely meet death. When you leave the house determined not to see it again you will come home safely; when you have any thought of returning you will not return. You may not be in the wrong to think that the world is always subject to change, but the warrior must not entertain this way of thinking, for his fate is always determined."
Example Output:
Who was Takeda's rival?
