Input: Read this: The largest producers of cotton, currently (2009), are China and India, with annual production of about 34 million bales and 33.4 million bales, respectively; most of this production is consumed by their respective textile industries. The largest exporters of raw cotton are the United States, with sales of $4.9 billion, and Africa, with sales of $2.1 billion. The total international trade is estimated to be $12 billion. Africa's share of the cotton trade has doubled since 1980. Neither area has a significant domestic textile industry, textile manufacturing having moved to developing nations in Eastern and South Asia such as India and China. In Africa, cotton is grown by numerous small holders. Dunavant Enterprises, based in Memphis, Tennessee, is the leading cotton broker in Africa, with hundreds of purchasing agents. It operates cotton gins in Uganda, Mozambique, and Zambia. In Zambia, it often offers loans for seed and expenses to the 180,000 small farmers who grow cotton for it, as well as advice on farming methods. Cargill also purchases cotton in Africa for export.
Question: What company is the top cotton broker in India?

QUES: Pain is a distressing feeling often caused by intense or damaging stimuli, such as stubbing a toe, burning a finger, putting alcohol on a cut, and bumping the "funny bone". Because it is a complex, subjective phenomenon, defining pain has been a challenge. The International Association for the Study of Pain's widely used definition states: "Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage." In medical diagnosis, pain is a symptom.

Why has defining pain been a challenge?
What is the answer?
ANS: complex, subjective phenomenon

QUES: Bermuda was discovered in 1503 by Spanish explorer Juan de Bermudez. It is mentioned in Legatio Babylonica, published in 1511 by historian Pedro Martir de Angleria, and was also included on Spanish charts of that year. Both Spanish and Portuguese ships used the islands as a replenishment spot to take on fresh meat and water. Legends arose of spirits and devils, now thought to have stemmed from the calls of raucous birds (most likely the Bermuda petrel, or Cahow) and the loud noise heard at night from wild hogs. Combined with the frequent storm-wracked conditions and the dangerous reefs, the archipelago became known as the Isle of Devils. Neither Spain nor Portugal tried to settle it.
When was Legatio Babylonica published by Pedro Angleria de Martir?

According to Y chromosome studies by Sanchez et al. (2005), Cruciani et al. (2004, 2007), the Somalis are paternally closely related to other Afro-Asiatic-speaking groups in Northeast Africa. Besides comprising the majority of the Y-DNA in Somalis, the E1b1b1a (formerly E3b1a) haplogroup also makes up a significant proportion of the paternal DNA of Ethiopians, Sudanese, Egyptians, Berbers, North African Arabs, as well as many Mediterranean populations. Sanchez et al. (2005) observed the M78 subclade of E1b1b in about 77% of their Somali male samples. According to Cruciani et al. (2007), the presence of this subhaplogroup in the Horn region may represent the traces of an ancient migration from Egypt/Libya. After haplogroup E1b1b, the second most frequently occurring Y-DNA haplogroup among Somalis is the West Asian haplogroup T (M70). It is observed in slightly more than 10% of Somali males. Haplogroup T, like haplogroup E1b1b, is also typically found among populations of Northeast Africa, North Africa, the Near East and the Mediterranean.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What percentage of Somali males had DNA containing the M78 subclade of E1b1b?
Ah, so.. 77%

Question: The party's decision-making bodies on a national level formally include the National Executive Committee (NEC), Labour Party Conference and National Policy Forum (NPF)although in practice the Parliamentary leadership has the final say on policy. The 2008 Labour Party Conference was the first at which affiliated trade unions and Constituency Labour Parties did not have the right to submit motions on contemporary issues that would previously have been debated. Labour Party conferences now include more "keynote" addresses, guest speakers and question-and-answer sessions, while specific discussion of policy now takes place in the National Policy Forum.
Try to answer this question if possible: What includes less keynote addresses now?
Answer: unanswerable
