Input: Read this: In 1933, Herbert Chapman, wanting his players to be more distinctly dressed, updated the kit, adding white sleeves and changing the shade to a brighter pillar box red. Two possibilities have been suggested for the origin of the white sleeves. One story reports that Chapman noticed a supporter in the stands wearing a red sleeveless sweater over a white shirt; another was that he was inspired by a similar outfit worn by the cartoonist Tom Webster, with whom Chapman played golf. Regardless of which story is true, the red and white shirts have come to define Arsenal and the team have worn the combination ever since, aside from two seasons. The first was 196667, when Arsenal wore all-red shirts; this proved unpopular and the white sleeves returned the following season. The second was 200506, the last season that Arsenal played at Highbury, when the team wore commemorative redcurrant shirts similar to those worn in 1913, their first season in the stadium; the club reverted to their normal colours at the start of the next season. In the 200809 season, Arsenal replaced the traditional all-white sleeves with red sleeves with a broad white stripe.
Question: What color was Arsenal's sleeves before 1933?

QUES: Asthma is characterized by recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing. Sputum may be produced from the lung by coughing but is often hard to bring up. During recovery from an attack, it may appear pus-like due to high levels of white blood cells called eosinophils. Symptoms are usually worse at night and in the early morning or in response to exercise or cold air. Some people with asthma rarely experience symptoms, usually in response to triggers, whereas others may have marked and persistent symptoms.

What is produced in the lungs by coughing?
What is the answer?
ANS: Sputum

QUES: The Persian Gulf War was a conflict between Iraq and a coalition force of 34 nations led by the United States. The lead up to the war began with the Iraqi invasion of Kuwait in August 1990 which was met with immediate economic sanctions by the United Nations against Iraq. The coalition commenced hostilities in January 1991, resulting in a decisive victory for the U.S. led coalition forces, which drove Iraqi forces out of Kuwait with minimal coalition deaths. Despite the low death toll, over 180,000 US veterans would later be classified as "permanently disabled" according to the US Department of Veterans Affairs (see Gulf War Syndrome). The main battles were aerial and ground combat within Iraq, Kuwait and bordering areas of Saudi Arabia. Land combat did not expand outside of the immediate Iraq/Kuwait/Saudi border region, although the coalition bombed cities and strategic targets across Iraq, and Iraq fired missiles on Israeli and Saudi cities.
When did hostilities in the Chinese Gulf War begin?

Despite their close genetic relationship and the ability to inter-breed, there are a number of diagnostic features to distinguish the gray wolves from domestic dogs. Domesticated dogs are clearly distinguishable from wolves by starch gel electrophoresis of red blood cell acid phosphatase. The tympanic bullae are large, convex and almost spherical in gray wolves, while the bullae of dogs are smaller, compressed and slightly crumpled. Compared to equally sized wolves, dogs tend to have 20% smaller skulls and 30% smaller brains.:35 The teeth of gray wolves are also proportionately larger than those of dogs; the premolars and molars of wolves are much less crowded and have more complex cusp patterns. Wolves do not have dewclaws on their back legs, unless there has been admixture with dogs. Dogs lack a functioning pre-caudal gland, and most enter estrus twice yearly, unlike gray wolves which only do so once a year. Dogs require fewer calories to function than wolves. The dog's limp ears may be the result of atrophy of the jaw muscles. The skin of domestic dogs tends to be thicker than that of wolves, with some Inuit tribes favoring the former for use as clothing due to its greater resistance to wear and tear in harsh weather.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Dogs having ears that are not erect may be due to what?
Ah, so.. atrophy of the jaw muscles.

Question: Israel is home to many Palestinian musicians, including internationally acclaimed oud and violin virtuoso Taiseer Elias, singer Amal Murkus, and brothers Samir and Wissam Joubran. Israeli Arab musicians have achieved fame beyond Israel's borders: Elias and Murkus frequently play to audiences in Europe and America, and oud player Darwish Darwish (Prof. Elias's student) was awarded first prize in the all-Arab oud contest in Egypt in 2003. The Jerusalem Academy of Music and Dance has an advanced degree program, headed by Taiseer Elias, in Arabic music.[citation needed]
Try to answer this question if possible: Who is the head of the advanced degree program in Arabic music?
Answer: Taiseer Elias

Question: Liber Aboali Abincine de Anima in arte Alchemiae was the most influential, having influenced later medieval chemists and alchemists such as Vincent of Beauvais. However Anawati argues (following Ruska) that the de Anima is a fake by a Spanish author. Similarly the Declaratio is believed not to be actually by Avicenna. The third work (The Book of Minerals) is agreed to be Avicenna's writing, adapted from the Kitab al-Shifa (Book of the Remedy). Ibn Sina classified minerals into stones, fusible substances, sulfurs, and salts, building on the ideas of Aristotle and Jabir. The epistola de Re recta is somewhat less sceptical of alchemy; Anawati argues that it is by Avicenna, but written earlier in his career when he had not yet firmly decided that transmutation was impossible.
Try to answer this question if possible: What is definitely seen as being written by Avicenna?
Answer:
The Book of Minerals
