Input: Consider Input: On to the Twentieth Century: The British extended their control over the peninsula by putting together the whole panoply of colonial administrationcivil service, public works, judiciary force, police force, post office, education, and land regulationwith teams of British administrators, teachers, engineers, and doctors to go with it. At the same time, the tin industry, dominated by Chinese using labor-intensive methods in the 19th century, passed increasingly into Western hands, who employed the modern technology of gravel pumps and mining dredges. Petroleum had been found in northern Borneo, at Miri, and in Brunei, and the Anglo-Dutch Shell company used Singapore as its regional depot for its oil supplies and exports. But the major breakthrough for the Malay economy was the triumph of rubber, when Singapore's new garden director, Henry Ridle ("Rubber Ridley" to his friends, "Mad Ridley" to all doubting Thomases) had developed new planting and tapping methods and painstakingly spread his faith in rubber around the peninsula. World demand increased with the growth of the motor-car and electrical industries, and sky-rocketed during World War I. By 1920, Malaya was producing 53 percent of the world's rubber, which had overtaken tin as its main source of income. The Malay ruling class again took a back seat. Together with effective control of the rubber and tin industries, the British now firmly held the reins of government. The sultans were left in charge of local and religious affairs, content with their prestige, prosperity, and security. The census of 1931 served as an alarm signal for the Malay national consciousness. Bolstered by a new influx of immigrants to meet the rubber and tin booms of the 1920s, non-Malays now slightly outnumbered the indigenous population. The Great Depression of 1929 stepped up ethnic competition in the shrinking job market, and nationalism developed to safeguard Malay interests against the Chinese and Indians rather than the British imperial authority. Though hampered by the peninsula's division into the States and the Straits Settlements, relatively conservative Muslim intellectuals and community leaders came together at the Pan-Malayan Malay Congress in Kuala Lumpur in 1939. In Singapore the following year, they were joined by representatives from Sarawak and Brunei. Teachers and journalists urged the revival of the common Malay-Indonesian consciousness, split by the Anglo-Dutch dismemberment of the region in the 19th century. This spirit became a factor in the gathering clouds of war. <sep>What caused the Malay ruling class to take a back seat?<sep>Auto and electrical industry demand for rubber, which dramatically increased during World War I

Output: Yes

Input: Consider Input: After what seemed an eternity to Tibo, they arrived at the mouth of a cave between two rocky hills. The opening was low and narrow. A few saplings bound together with strips of rawhide closed it against stray beasts. Bukawai removed the primitive door and pushed Tibo within. The hyenas, snarling, rushed past him and were lost to view in the blackness of the interior. Bukawai replaced the saplings and seizing Tibo roughly by the arm, dragged him along a narrow, rocky passage. The floor was comparatively smooth, for the dirt which lay thick upon it had been trodden and tramped by many feet until few inequalities remained. The passage was tortuous, and as it was very dark and the walls rough and rocky, Tibo was scratched and bruised from the many bumps he received. Bukawai walked as rapidly through the winding gallery as one would traverse a familiar lane by daylight. He knew every twist and turn as a mother knows the face of her child, and he seemed to be in a hurry. He jerked poor little Tibo possibly a trifle more ruthlessly than necessary even at the pace Bukawai set; but the old witch-doctor, an outcast from the society of man, diseased, shunned, hated, feared, was far from possessing an angelic temper. Nature had given him few of the kindlier characteristics of man, and these few Fate had eradicated entirely. Shrewd, cunning, cruel, vindictive, was Bukawai, the witch-doctor. <sep>Who knew every twist and turn of the gallery?<sep>Bukawai

Output: Yes

Input: Consider Input: Before the mysterious disappearance of one of its passenger jets this month, Malaysia wasn't a country used to finding itself dominating headlines around the world. Some of its Southeast Asian neighbors, including Indonesia and the Philippines, have suffered devastating natural disasters in recent years and are all too familiar with the media frenzy that accompanies a major crisis. But Malaysia has largely managed to stay out of the international spotlight since its independence from British colonial rule more than half a century ago. "It is one of these countries, because of its geography, that doesn't have earthquakes," said Ernest Bower, senior adviser for Southeast Asia studies at the Center for Strategic and International Studies. "It doesn't have tsunamis. It hasn't been tested with a disaster like this." The disappearance of Malaysia Airlines Flight 370 has thrust the government into the dazzling glare of worldwide attention. And it hasn't emerged with very good grades. "I think on a stress test, they're failing," Bower told CNN's Jake Tapper, pointing to the government's coordination of different agencies and communication with other countries. China among critics Criticism and complaints have come from other countries involved in the search for the missing plane, including China and Vietnam, and from the relatives of passengers. Malaysian officials have created confusion by issuing contradictory statements on key aspects of the investigation. The majority of the people on board the plane were Chinese, and Beijing has increasingly voiced its displeasure with the search, especially after Malaysia announced over the weekend that evidence suggested the plane had been deliberately flown west into the Indian Ocean, away from its last confirmed location over the South China Sea. "The new information means the intensive search in the South China Sea for the whole past week was worthless and would never bear fruit," said a commentary published by China's state-run news agency Xinhua. "Even worse, the golden time for saving possible survivors, if any, was generously wasted." <sep>What has the new information from Malaysia potentially wasted time for?<sep>"Saving possible survivors"
Output: Yes
