The problem: Answer a question about this article:
In some countries, law enforcement uses race to profile suspects. This use of racial categories is frequently criticized for perpetuating an outmoded understanding of human biological variation, and promoting stereotypes. Because in some societies racial groupings correspond closely with patterns of social stratification, for social scientists studying social inequality, race can be a significant variable. As sociological factors, racial categories may in part reflect subjective attributions, self-identities, and social institutions.

Problem: Please answer a question about the following article about Jehovah%27s Witnesses:
From 1932, it was taught that the "little flock" of 144,000 would not be the only people to survive Armageddon. Rutherford explained that in addition to the 144,000 "anointed" who would be resurrected—or transferred at death—to live in heaven to rule over earth with Christ, a separate class of members, the "great multitude," would live in a paradise restored on earth; from 1935, new converts to the movement were considered part of that class. By the mid-1930s, the timing of the beginning of Christ's presence (Greek: parousía), his enthronement as king, and the start of the "last days" were each moved to 1914.
Where would the great multitude live?
A: a paradise restored on earth

The most innovative period of Cubism was before 1914. After World War I, with the support given by the dealer Léonce Rosenberg, Cubism returned as a central issue for artists, and continued as such until the mid-1920s when its avant-garde status was rendered questionable by the emergence of geometric abstraction and Surrealism in Paris. Many Cubists, including Picasso, Braque, Gris, Léger, Gleizes, and Metzinger, while developing other styles, returned periodically to Cubism, even well after 1925. Cubism reemerged during the 1920s and the 1930s in the work of the American Stuart Davis and the Englishman Ben Nicholson. In France, however, Cubism experienced a decline beginning in about 1925. Léonce Rosenberg exhibited not only the artists stranded by Kahnweiler’s exile but others including Laurens, Lipchitz, Metzinger, Gleizes, Csaky, Herbin and Severini. In 1918 Rosenberg presented a series of Cubist exhibitions at his Galerie de l’Effort Moderne in Paris. Attempts were made by Louis Vauxcelles to claim that Cubism was dead, but these exhibitions, along with a well-organized Cubist show at the 1920 Salon des Indépendants and a revival of the Salon de la Section d’Or in the same year, demonstrated it was still alive.
In what year did Rosenberg exhibit Cubist works at  Galerie de l’Effort Moderne?
1918
