[EX Q]: There are several reasons an otherwise valid and agreed upon treaty may be rejected as a binding international agreement, most of which involve problems created at the formation of the treaty.[citation needed] For example, the serial Japan-Korea treaties of 1905, 1907 and 1910 were protested; and they were confirmed as "already null and void" in the 1965 Treaty on Basic Relations between Japan and the Republic of Korea.

[EX Q]: 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.
[EX A]: Before what year was Cubism considered the most innovative? 

[EX Q]: Her mature artistic statement was visible in True Blue (1986) and Like a Prayer (1989). In True Blue, she incorporated classical music in order to engage an older audience who had been skeptical of her music. Like a Prayer introduced live recorded songs and incorporated different genres of music, including dance, funk, R&B and gospel music. Her versatility was further shown on I'm Breathless, which consists predominantly of the 1940s Broadway showtune-flavoured jazz, swing and big band tracks. Madonna continued to compose ballads and uptempo dance songs for Erotica (1992) and Bedtime Stories (1994). Both albums explored element of new jack swing, with Jim Farber from Entertainment Weekly saying that "she could actually be viewed as new jack swing's godmother." She tried to remain contemporary by incorporating samples, drum loops and hip hop into her music. With Ray of Light, Madonna brought electronic music from its underground status into massive popularity in mainstream music scene.
