Article: A 2009 Cochrane review concluded that thiazide antihypertensive drugs reduce the risk of death (RR 0.89), stroke (RR 0.63), coronary heart disease (RR 0.84), and cardiovascular events (RR 0.70) in people with high blood pressure. In the ensuring years other classes of antihypertensive drug were developed and found wide acceptance in combination therapy, including loop diuretics (Lasix/furosemide, Hoechst Pharmaceuticals, 1963), beta blockers (ICI Pharmaceuticals, 1964) ACE inhibitors, and angiotensin receptor blockers. ACE inhibitors reduce the risk of new onset kidney disease [RR 0.71] and death [RR 0.84] in diabetic patients, irrespective of whether they have hypertension.

Question: What do ACE inhibitors do?
Ans: reduce the risk of new onset kidney disease [RR 0.71] and death [RR 0.84] in diabetic patients

Here is a question about this article: The Columbia Encyclopedia distinguishes between the Yuan dynasty and the other Mongol Empire khanates of Ilkhanate, Chagatai Khanate and the Golden Horde. It describes the Yuan dynasty as "A Mongol dynasty of China that ruled from 1271 to 1368, and a division of the great empire conquered by the Mongols. Founded by Kublai Khan, who adopted the Chinese dynastic name of Yuan in 1271." The Encyclopedia Americana describes the Yuan dynasty as "the line of Mongol rulers in China" and adds that the Mongols "proclaimed a Chinese-style Yuan dynasty at Khanbaliq (Beijing)." The Metropolitan Museum of Art writes that the Mongol rulers of the Yuan dynasty "adopted Chinese political and cultural models; ruling from their capitals in Dadu, they assumed the role of Chinese emperors," although Tibetologist Thomas Laird dismissed the Yuan dynasty as a non-Chinese polity and plays down its Chinese characteristics. The Metropolitan Museum of Art also noted that in spite of the gradual assimilation of Yuan monarchs, the Mongol rulers largely ignored the literati and imposed harsh policies discriminating against southern Chinese. In his Kublai Khan: His Life and Times, Rossabi explains that Kublai "created government institutions that either resembled or were the same as the traditional Chinese ones", and he "wished to signal to the Chinese that he intended to adopt the trappings and style of a Chinese ruler".
What is the answer to this question: How did the The Columbia Encyclopedia describe the Yuan dynasty?
****
So... A Mongol dynasty of China

The problem: Answer a question about this article:
Infectious diseases are sometimes called contagious disease when they are easily transmitted by contact with an ill person or their secretions (e.g., influenza). Thus, a contagious disease is a subset of infectious disease that is especially infective or easily transmitted. Other types of infectious/transmissible/communicable diseases with more specialized routes of infection, such as vector transmission or sexual transmission, are usually not regarded as "contagious", and often do not require medical isolation (sometimes loosely called quarantine) of victims. However, this specialized connotation of the word "contagious" and "contagious disease" (easy transmissibility) is not always respected in popular use.
What sets a contagious disease after from a standard infectious disease?
****
The answer: especially infective or easily transmitted

Problem: Please answer a question about the following article about Buddhism:
Two major extant branches of Buddhism are generally recognized by scholars: Theravada ("The School of the Elders") and Mahayana ("The Great Vehicle"). Vajrayana, a body of teachings attributed to Indian siddhas, may be viewed as a third branch or merely a part of Mahayana. Theravada has a widespread following in Sri Lanka and Southeast Asia. Mahayana which includes the traditions of Pure Land, Zen, Nichiren Buddhism, Shingon, and Tiantai (Tendai) is found throughout East Asia. Tibetan Buddhism, which preserves the Vajrayana teachings of eighth century India, is practiced in regions surrounding the Himalayas, Mongolia and Kalmykia. Buddhists number between an estimated 488 million[web 1] and 535 million, making it one of the world's major religions.
Theravada means what?

Season eleven, however, suffered a steep drop in ratings, a drop attributed by some to the arrival of new shows such as The Voice and The X-Factor. The ratings for the first two episodes of season eleven fell 1621% in overall viewer numbers and 2427% in the 18/49 demo, while the season finale fell 27% in total viewer number and 30% in the 18-49 demo. The average viewership for the season fell below 20 million viewers the first time since 2003, a drop of 23% in total viewers and 30% in the 18/49 demo. For the first time in eight years, American Idol lost the leading position in both the total viewers number and the 18/49 demo, coming in second to NBC Sunday Night Football, although the strengths of Idol in its second year in the Wednesday-Thursday primetime slots helped Fox achieve the longest period of 18-49 demographic victory in the Nielsen ratings, standing at 8 straight years from 2004 to 2012.

How long did Fox reign in the 18-49 demographics in the Nielsen ratings?
Answer: eight years

Cuba, like many Spanish territories, wanted to break free from Spain. A pro-independence movement in Cuba was supported by the U.S., and Cuban guerrilla leaders wanted annexation to the United States, but Cuban revolutionary leader Jose Marti called for Cuban nationhood. When the U.S. battleship Maine sank in Havana Harbor, the U.S. blamed Spain and the SpanishAmerican War broke out in 1898. After the U.S. won, Spain relinquished claim of sovereignty over territories, including Cuba. The U.S. administered Cuba as a protectorate until 1902. Several decades later in 1959, the corrupt Cuban government of U.S.-backed Fulgencio Batista was overthrown by Fidel Castro. Castro installed a MarxistLeninist government allied with the Soviet Union, which has been in power ever since.
What government did Castro install?
MarxistLeninist government
