In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Ex Input:
Which of the following did not occur in the 20th century: urbanization, the spread of the Ottoman Empire, or wars?, Context: South Slavic historically formed a dialect continuum, i.e. each dialect has some similarities with the neighboring one, and differences grow with distance. However, migrations from the 16th to 18th centuries resulting from the spread of Ottoman Empire on the Balkans have caused large-scale population displacement that broke the dialect continuum into many geographical pockets. Migrations in the 20th century, primarily caused by urbanization and wars, also contributed to the reduction of dialectal differences.

Ex Output:
spread of Ottoman Empire


Ex Input:
What economic improvement did the successors make?, Context: Louis-Philippe was overthrown by a popular uprising in the streets of Paris in 1848. His successor, Napoleon III, and the newly appointed prefect of the Seine, Georges-Eugène Haussmann, launched a gigantic public works project to build wide new boulevards, a new opera house, a central market, new aqueducts, sewers, and parks, including the Bois de Boulogne and Bois de Vincennes. In 1860, Napoleon III also annexed the surrounding towns and created eight new arrondissements, expanding Paris to its current limits.

Ex Output:
central market


Ex Input:
How do you distinguish a dialect from a different language?, Context: There is no universally accepted criterion for distinguishing two different languages from two dialects (i.e. varieties) of the same language. A number of rough measures exist, sometimes leading to contradictory results. The distinction is therefore subjective and depends on the user's frame of reference. For example, there is discussion about if the Limón Creole English must be considered as "a kind" of English or a different language. This creole is spoken in the Caribbean coast of Costa Rica (Central America) by descendant of Jamaican people. The position that Costa Rican linguists support depends on the University they belong.

Ex Output:

subjective
