Ex Input:
What kind of dogs usually have docked tails?, Context: There are many different shapes for dog tails: straight, straight up, sickle, curled, or cork-screw. As with many canids, one of the primary functions of a dog's tail is to communicate their emotional state, which can be important in getting along with others. In some hunting dogs, however, the tail is traditionally docked to avoid injuries. In some breeds, such as the Braque du Bourbonnais, puppies can be born with a short tail or no tail at all.

Ex Output:
hunting

Ex Input:
What happened earlier, the French invasion in 1672 or Utrecht becoming the centre of the non-Roman Old Catholic Churches in the world?, Context: The fortified city temporarily fell to the French invasion in 1672 (the Disaster Year); where the French invasion was only stopped west of Utrecht at the Old Hollandic Waterline. In 1674, only two years after the French left, the centre of Utrecht was struck by a tornado. The halt to building before construction of flying buttresses in the 15th century now proved to be the undoing of the central section of the cathedral of St Martin church which collapsed; creating the current Dom square between the tower and choir. In 1713, Utrecht hosted one of the first international peace negotiations when the Treaty of Utrecht settled the War of the Spanish Succession. Since 1723 Utrecht became the centre of the non-Roman Old Catholic Churches in the world.

Ex Output:
the French invasion in 1672

Ex Input:
what is the last ethnicity mentioned?, Context: After the formation of the People's Republic of China in 1949, the Chinese government named the Western nations, led by the United States, as the biggest threat to its national security. Basing this judgment on China's century of humiliation beginning in the early 19th century, American support for the Nationalists during the Chinese Civil War, and the ideological struggles between revolutionaries and reactionaries, the Chinese leadership believed that China would become a critical battleground in the United States' crusade against Communism. As a countermeasure and to elevate China's standing among the worldwide Communist movements, the Chinese leadership adopted a foreign policy that actively promoted Communist revolutions throughout territories on China's periphery.

Ex Output:
Chinese
