Problem: Crimean War:

The immediate chain of events leading to France and the United Kingdom declaring war on Russia on 27 and 28 March 1854 came from the ambition of the French emperor Napoleon III to restore the grandeur of France. He wanted Catholic support that would come his way if he attacked Eastern Orthodoxy, as sponsored by Russia.:103 The Marquis Charles de La Valette was a zealous Catholic and a leading member of the "clerical party," which demanded French protection of the Roman Catholic rights to the holy places in Palestine. In May 1851, Napoleon appointed La Valette as his ambassador to the Porte (the Ottoman Empire).:79 The appointment was made with the intent of forcing the Ottomans to recognise France as the "sovereign authority" over the Christian population.:19 Russia disputed this attempted change in authority. Pointing to two more treaties, one in 1757 and the 1774 Treaty of Kucuk Kaynarca, the Ottomans reversed their earlier decision, renouncing the French treaty and insisting that Russia was the protector of the Orthodox Christians in the Ottoman Empire.

Problem: Jehovah%27s Witnesses:

Rutherford centralized organizational control of the Watch Tower Society. In 1919, he instituted the appointment of a director in each congregation, and a year later all members were instructed to report their weekly preaching activity to the Brooklyn headquarters. At an international convention held at Cedar Point, Ohio, in September 1922, a new emphasis was made on house-to-house preaching. Significant changes in doctrine and administration were regularly introduced during Rutherford's twenty-five years as president, including the 1920 announcement that the Jewish patriarchs (such as Abraham and Isaac) would be resurrected in 1925, marking the beginning of Christ's thousand-year Kingdom. Disappointed by the changes, tens of thousands of defections occurred during the first half of Rutherford's tenure, leading to the formation of several Bible Student organizations independent of the Watch Tower Society, most of which still exist. By mid-1919, as many as one in seven of Russell-era Bible Students had ceased their association with the Society, and as many as two-thirds by the end of the 1920s.

Problem: History of India:

One of the most important events of the 19th century was the rise of Indian nationalism, leading Indians to seek first "self-rule" and later "complete independence". However, historians are divided over the causes of its rise. Probable reasons include a "clash of interests of the Indian people with British interests", "racial discriminations", "the revelation of India's past", "inter-linking of the new social groups in different regions", and Indians coming in close contact with "European education".

What can only be listed without absolute firmness in the nationalism movement?

A: Probable reasons

Problem: Steven Spielberg:

In early 2009, Spielberg shot the first film in a planned trilogy of motion capture films based on The Adventures of Tintin, written by Belgian artist Herge, with Peter Jackson. The Adventures of Tintin: The Secret of the Unicorn, was not released until October 2011, due to the complexity of the computer animation involved. The world premiere took place on October 22, 2011 in Brussels, Belgium. The film was released in North American theaters on December 21, 2011, in Digital 3D and IMAX. It received generally positive reviews from critics, and grossed over $373 million worldwide. The Adventures of Tintin won the award for Best Animated Feature Film at the Golden Globe Awards that year. It is the first non-Pixar film to win the award since the category was first introduced. Jackson has been announced to direct the second film.
