Article: The language has numerous regional dialects which are generally not mutually intelligible. It is employed throughout the Tibetan plateau and Bhutan and is also spoken in parts of Nepal and northern India, such as Sikkim. In general, the dialects of central Tibet (including Lhasa), Kham, Amdo and some smaller nearby areas are considered Tibetan dialects. Other forms, particularly Dzongkha, Sikkimese, Sherpa, and Ladakhi, are considered by their speakers, largely for political reasons, to be separate languages. However, if the latter group of Tibetan-type languages are included in the calculation, then 'greater Tibetan' is spoken by approximately 6 million people across the Tibetan Plateau. Tibetan is also spoken by approximately 150,000 exile speakers who have fled from modern-day Tibet to India and other countries.

Question: How many people across the Tibetan Plateau speak 'greater Tibetan'?
Ans: approximately 6 million

Article: The National History Museum of Montevideo is located in the historical residence of General Fructuoso Rivera. It exhibits artifacts related to the history of Uruguay. In a process begun in 1998, the National Museum of Natural History (1837) and the National Museum of Anthropology (1981), merged in 2001, becoming the National Museum of Natural History and Anthropology. In July 2009, the two institutions again became independent. The Historical Museum has annexed eight historical houses in the city, five of which are located in the Ciudad Vieja. One of them, on the same block with the main building, is the historic residence of Antonio Montero, which houses the Museo Romantico.

Question: The National History Museum of Montevideo is located where?
Ans: the historical residence of General Fructuoso Rivera

Article: Neutering reduces problems caused by hypersexuality, especially in male dogs. Spayed female dogs are less likely to develop some forms of cancer, affecting mammary glands, ovaries, and other reproductive organs. However, neutering increases the risk of urinary incontinence in female dogs, and prostate cancer in males, as well as osteosarcoma, hemangiosarcoma, cruciate ligament rupture, obesity, and diabetes mellitus in either sex.

Question: According to the text, what is a possible side effect of neutering a female dog?
Ans: urinary incontinence

Article: A study conducted in 1972 and 1981, documented by Robert Ulrich, surveyed 23 surgical patients assigned to rooms looking out on a natural scene. The study concluded that patients assigned to rooms with windows allowing lots of natural light had shorter postoperative hospital stays, received fewer negative evaluative comments in nurses' notes, and took fewer potent analegesics than 23 matched patients in similar rooms with windows facing a brick wall. This study suggests that due to the nature of the scenery and daylight exposure was indeed healthier for patients as opposed to those exposed to little light from the brick wall. In addition to increased work performance, proper usage of windows and daylighting crosses the boundaries between pure aesthetics and overall health.

Question: Who documented 23 surgical patients assigned rooms looking out on a natural scene?
Ans:
Robert Ulrich
