question:
Passage: SMS Kronprinz Erzherzog Rudolf was a unique ironclad warship built for the Austro-Hungarian Navy in the 1880s. The last ironclad completed for the Austro-Hungarian Navy, Kronprinz Erzherzog Rudolf was laid down in January 1884, launched in July 1887, and completed in September 1889. She was armed with a main battery of three guns and had compound steel plating of the same thickness on her armored belt. The ship had an uneventful career, in large part due to her rapid obsolescence. She made trips to foreign countries to represent Austria-Hungary, but was reduced to a coastal defense ship by 1906. She continued in this role through World War I, based at Cattaro Bay, where her crew took part in the Cattaro Mutiny in early 1918. After the war, Kronprinz Erzherzog Rudolf was transferred to the Navy of the Kingdom of Serbs, Croats and Slovenes and renamed Kumbor, but she remained in their inventory for only a year, being sold for scrap in 1922.

question:
Passage: In 1983 elections, N. T. Rama Rao came to power defeating the Indian National Congress. He praised the Naxalites for their patriotism before the elections. After coming to power, he demonstrated no significant change in government policy towards the revolutionary movement. Particularly after he was elected for a second time in 1985, his government put all its efforts to suppress the Naxalite movement in the state. Varavara Rao too was subjected to severe repression during this time. Six cases were foisted against him in 1985 alone. In July that year, along with functionaries of other people's organisations, he undertook an all India tour to make the people aware of the repression that was going on in Andhra Pradesh. After visiting Maharashtra, Madhya Pradesh, Bihar, West Bengal, New Delhi and Tamil Nadu, Varavara Rao returned to Andhra Pradesh in September to attend court cases. Dr. Ramanatham, a pediatrician and civil liberties activist was a close friend of Varavara Rao. While killing Dr. Ramanatham, and on several other occasions, police openly declared that killing Varavara Rao was their aim. With his life at risk, Varavara Rao could not discharge his duties as Secretary of Virasam and spokesperson of revolutionary literary movement. He was not able to move freely in Andhra Pradesh. Warangal has become a forbidden place for him. Armed and unarmed ruffians and police in civil clothes attacked his house on several occasions. Persecution against his friends in the movement was also mounted. Taking into consideration all these developments, Varavara Rao chose to cancel his bail in Secunderabad Conspiracy Case. On his request, his bail was cancelled and he was sent to jail on 26 December 1985.

question:
Passage: In 1592, during the war with Spain, an English fleet had captured a large Portuguese galleon off the Azores, the Madre de Deus, loaded with 900 tons of merchandise from India and China, worth an estimated half a million pounds (nearly half the size of English Treasury at the time). This foretaste of the riches of the East galvanized interest in the region. That same year, Dutch merchants sent Cornelis de Houtman to Lisbon, to gather as much information as he could about the Spice Islands. In 1595, merchant and explorer Jan Huyghen van Linschoten, having traveled widely in the Indian Ocean at the service of the Portuguese, published a travel report in Amsterdam, the "Reys-gheschrift vande navigatien der Portugaloysers in Orienten" ("Report of a journey through the navigations of the Portuguese in the East"). The published report included vast directions on how to navigate ships between Portugal and the East Indies and to Japan. Dutch and British interest fed by new information led to a movement of commercial expansion, and the foundation of the English East India Company, in 1600, and Dutch East India Company (VOC), in 1602, allowing the entry of chartered companies in the so-called East Indies.
