Context_1 : The 2010 China floods began in early May 2010. Three hundred and ninety-two people died, and a further 232 people were reported missing as of June 30, 2010, including 57 people in a landslide in Guizhou. Fifty-three of the deaths occurred from the flooding and landslides between May 31 and June 3, and 266 deaths occurred between June 13 and June 29. Four hundred and twenty four people were killed by the end of June, including 42 from the Guizhou landslide; 277 more were killed and 147 left missing in the first two weeks of July, bringing the death toll as of August 5 to 1,072. A landslide in early August in Gansu killed at least 1,471 people and left 294 missing. In total, the flooding and landslides killed at least 3,185 people in China by August 31. More than 230 million people in 28 provinces, municipalities and regions, especially the southern and central provinces and regions of Zhejiang, Fujian, Jiangxi, Hubei, Hunan, Guangdong, Guangxi, Chongqing Municipality, Gansu, Sichuan and Guizhou, and the northeastern province of Jilin were affected, while at least 4.66 million people were evacuated because of the risk of flooding and landslides in the latter half of June. By early August, over 12 million people were evacuated, and that number rose to 15.2 million by August 31. Context_2 : Cameroonian American are Americans of Cameroonian descent. According to the census of 2010, in the United States there were 16,894 Americans of Cameroonian origin. Many people from present-day Cameroon arrived in the United States as slaves during the antebellum period. Consequently, many African Americans today have discovered through DNA analysis that they are mainly or at least partly descended from Cameroonian slaves. The American DNA Company discovered that many of the 6,000 African Americans whose DNA they analyzed had at least one ancestor from current-day Cameroon. In addition, according to the 2007-2011 American Community Survey there are 33,181 Cameroonian-born people living in the United States. Context_3 : The El Ayyat train disaster happened at 02:00 on the morning of 20 February 2002 in an eleven-carriage passenger train travelling from Cairo to Luxor. A cooking gas cylinder exploded in the fifth carriage, creating a fire which engulfed seven third-class carriages, reducing them almost to cinders. The initial number of dead given by officials at the time was 383, all Egyptians. However, considering that seven carriages were burnt to the ground, and each carriage was packed with at least double the maximum carrying capacity of 150, this number is considered by many people to be a great underestimate. The dubious nature of the given death toll lies with the absence of a full passenger list; accounting for those missing was almost impossible at the time. In addition, the fire was so intense and the carriages so badly burned that many corpses had been reduced to ash. As there was no means of communication between the driver and the rear carriages, the driver did not know of the fire until about two hours after it had begun, resulting in many people, attempting to flee from the overcrowded carriages, jumping to their death. Some important Egyptians have commentated that the official number of 383 dead is grossly inaccurate and was an attempt to lessen the damage done to the reputation of the government. Many people consider a number of about 1000 deaths to be more accurate. Context_4 : Kume no Heinai-do ( ) is a small folk shrine located in Asakusa in Taito, Tokyo. The shrine houses a stone statue of Kume no Heinai, a samurai from the early Edo period (17th century). According to the Asakusa tourism bureau, there are few facts about the life of Kume no Heinai, but he is said to have died in 1683. Oral tradition holds that Heinai excelled in Kenjutsu, the martial art of swordsmanship, killing many people over the years. In the latter half of his life, he is said to have lived in the Senso-ji temple in Asakusa where he devoted himself to Zen-Buddhism and held religious services in honor of the people he killed. Shortly before his death he ordered his followers to carve his likeness on a stone and bury it near the Niomon the entrance to the Buddhist temple and a busy district in the city. His wish was to have his statue be stepped on by as many people as possible in order to expiate the crimes he committed in life. The statue was eventually retrieved and is now stored inside the shrine itself. It is because of this that the shrine initially carried the name "Fumitsuke" ( ) , which means "to tread on", but over time the meaning was lost and the shrine's name came to be spelled , which means "love letter". Both words are pronounced "Fumitsuke" and the shrine is now worshipped by the general public as a deity of marriage and match-making. Kume no Heinai-do was destroyed in March 1945 during World War II. The current temple was rebuilt in October 1978. Context_5 : The Sid El-Antri massacre took place on the night of 2324 December 1997 in two small villages near Tiaret, Algeria. The death toll is unclear; Reuters cites "at least 80", or 48 according to the government, "Le Jeune Independent" says 117 people were killed and 11 abducted by terrorists, and a timeline gives 53 (including 15 children) killed in Sidi el-Antri (or Sidi el-Antar, Sidi Lamri) and 28 in Shari. On the same day, 11 were killed further away in the Bainem area near Algiers. A few days later, another 26 civilians were killed in the Zouabria massacre, also near Tiaret. Context_6 : Although spinal cord injury (SCI) often causes sexual dysfunction, many people with SCI are able to have satisfying sex lives. Physical limitations acquired from SCI affect sexual function and sexuality in broader areas, which in turn has important effects on quality of life. Damage to the spinal cord impairs its ability to transmit messages between the brain and parts of the body below the level of the lesion. This results in lost or reduced sensation and muscle motion, and affects orgasm, erection, ejaculation, and vaginal lubrication. More indirect causes of sexual dysfunction include pain, weakness, and side effects of medications. Psycho-social causes include depression and altered self-image. Many people with SCI have satisfying sex lives, and many experience sexual arousal and orgasm. People with SCI employ a variety of adaptations to help carry on their sex lives healthily, by focusing on different areas of the body and types of sexual acts. Neural plasticity may account for increases in sensitivity in parts of the body that have not lost sensation, so people often find newly sensitive erotic areas of the skin in erogenous zones or near borders between areas of preserved and lost sensation. Context_7 : The June 2011 Peshawar bombings occurred on 12 June 2011 in Peshawar, Khyber Pakhtunkhwa, Pakistan. At least 34 people were killed, and more than 90 were injured, when two bombs exploded in a market around midnight. The first bomb went off around 11:50p.m. local time in Khyber market area, which is a commercial and residential area, and injured 3 people. After a crowd gathered in the area, a teen-aged suicide bomber on a motorcycle set off a second explosion, killing many people on the spot. About 10 kg of explosives were used in the second blast according to officials. Context_8 : The Niles Canyon ghost story is the Northern California variation on the vanishing hitchhiker archetype. There are many different variations of this story depending on whom you ask. All stories include a girl being involved in some sort of motorized vehicle accident on February 26 (year often changed). One variation of the story includes a girl being involved in a car crash on Niles Canyon road (off the 680 freeway in Sunol, California) on the way to her prom. The girl died on impact and to this day is said to haunt Niles Canyon road every February 26. The tale of the haunting goes that people traveling along Niles Canyon road (now Highway 84) on the night of February 26 will see a normal-looking high school-aged girl walking along the road in a prom dress (many people have said it is white). People traveling along the road (mostly those traveling alone) have said to have stopped and offered the girl a ride. She accepts the ride, giving the driver an address across the bridge (either Dumbarton or Bay Bridge depending on the storyteller). Once the driver gets to the beginning of the bridge, the girl will disappear. Sometimes people have gone to the address to find that a girl many years ago matching that description once lived there. Today, many people will travel along this treacherous pitch black road in the hopes of catching a glimpse of the Niles Canyon ghost. Context_9 : Frederick Walter Stephen West (29 September 1941 1 January 1995) was an English serial killer who committed at least 12 murders between 1967 and 1987 in Gloucestershire, the majority with his second wife, Rosemary West.
