Example Input: By 1937, Japan controlled Manchuria and was ready to move deeper into China. The Marco Polo Bridge Incident on 7 July 1937 provoked full-scale war between China and Japan. The Nationalist and Communist Chinese suspended their civil war to form a nominal alliance against Japan, and the Soviet Union quickly lent support by providing large amount of materiel to Chinese troops. In August 1937, Generalissimo Chiang Kai-shek deployed his best army to fight about 300,000 Japanese troops in Shanghai, but, after three months of fighting, Shanghai fell. The Japanese continued to push the Chinese forces back, capturing the capital Nanking in December 1937 and committed which was known as Nanking Massacre. In March 1938, Nationalist forces won their first victory at Taierzhuang. but then the city of Xuzhou was taken by Japanese in May. In June 1938, Japan deployed about 350,000 troops to invade Wuhan and captured it in October. The Japanese achieved major military victories, but world opinion—in particular in the United States—condemned Japan, especially after the Panay Incident.
Example Output: What incident occured on July 7, 1937?

Example Input: In the Western Balkans, South Slavs and Germanic Gepids intermarried with Avar invaders, eventually producing a Slavicized population.[citation needed] In Central Europe, the Slavs intermixed with Germanic and Celtic, while the eastern Slavs encountered Uralic and Scandinavian peoples. Scandinavians (Varangians) and Finnic peoples were involved in the early formation of the Rus' state but were completely Slavicized after a century. Some Finno-Ugric tribes in the north were also absorbed into the expanding Rus population. At the time of the Magyar migration, the present-day Hungary was inhabited by Slavs, numbering about 200,000, and by Romano-Dacians who were either assimilated or enslaved by the Magyars. In the 11th and 12th centuries, constant incursions by nomadic Turkic tribes, such as the Kipchaks and the Pechenegs, caused a massive migration of East Slavic populations to the safer, heavily forested regions of the north. In the Middle Ages, groups of Saxon ore miners settled in medieval Bosnia, Serbia and Bulgaria where they were Slavicized.
Example Output: Where did South Slavs and Germanic Gepids intermarried with Avar invaders?

Example Input: From 1938 until 1995, the U.S. Supreme Court did not invalidate any federal statute as exceeding Congress' power under the Commerce Clause. Most actions by the federal government can find some legal support among the express powers, such as the Commerce Clause, whose applicability has been narrowed by the Supreme Court in recent years. In 1995 the Supreme Court rejected the Gun-Free School Zones Act in the Lopez decision, and also rejected the civil remedy portion of the Violence Against Women Act of 1994 in the United States v. Morrison decision. Recently, the Commerce Clause was interpreted to include marijuana laws in the Gonzales v. Raich decision.
Example Output:
What happened between 1938 to 1995?
