Question: Susanna Maiolo attacked the pope in a country that has a population of how many people ?
Context: Vatican City ( ; Italian: "Città del Vaticano" ] ; Latin: "Civitas Vaticana" ), officially Vatican City State or the State of Vatican City (Italian: "Stato della Città del Vaticano" ; Latin: "Status Civitatis Vaticanae" ), is a country located within the city of Rome.  With an area of approximately 44 hectares (110 acres), and a population of 1,000, it is the smallest country in the world by both area and population.  However, formally it is not sovereign, with sovereignty being held by the Holy See. Kume no Heinai-dō (久米平内堂 ) is a small folk shrine located in Asakusa in Taitō, 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 Sensō-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 Niōmon – 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" (踏みつけ ) , which means "to tread on", but over time the meaning was lost and the shrine's name came to be spelled 文付け, 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-dō was destroyed in March 1945 during World War II.  The current temple was rebuilt in October 1978. The preferred walking speed is the speed at which humans or animals choose to walk.  Many people tend to walk at about 1.4 m/s .  Although many people are capable of walking at speeds upwards of 2.5 m/s , especially for short distances, they typically choose not to.  Individuals find slower or faster speeds uncomfortable. 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. Human population change is the difference between the size of the population from the beginning to the end of a certain time period.  In other words, population change refers to change in the number of people during a specific time period.  As a whole,the world population has not been stable; it has increased manifold.  Due to this constant changing population, the subject of demographics, the statistics of how many people there are in a given population, was created.  Demography can also be defined as the study of populations, and the factors that cause the most amount of population growth or decline.  The main measurements of demography include: birth rates, death rates, sex ratios, life expectancy, and migration rates.  All of these measures are found by a series of surveys and censuses conducted over a time period in order to compare how the population is changing.  Other ways to measure population demographics include the use of historical maps, aerial photographs, and census statistics.  One of the reasons why demographers use statistics about population change is because of the social and demographic transformations that the world experiences; significant challenges for the government and businesses will take effect depending on the degree of the population change. Praedecessores nostros was a papal encyclical written by Pope Pius IX on March 25, 1847 to address the crisis of the Great Irish Famine that occurred approximately between 1845 and 1850.  This event is known by many as the 19th century’s greatest natural disaster.  Pope Pius IX was born Giovanni Maria Mastai-Ferretti on May 13, 1792 in Senigallia, Italy.  He studied at the College of Volterra in Tuscany and was ordained as a priest in 1819.  Throughout the span of his life, Pope Pius IX served as the director of the Roman hospice of San Michele, Bishop of Imola, and Archbishop of Spoleto.  He was made a Cardinal (Catholicism) in 1840 and elected Pope in 1846.  Several important events that occurred during the papacy of Pope Pius IX are the unification of Italy, the First Vatican Council, the defining of the dogma of the Immaculate Conception, and 38 papal encyclicals.  "Praedecessores nostros" is one of the more significant papal decrees of the time because it addresses one of the most well known events in history.  The Great Irish Famine was caused by the mysterious fungus, Phytophthora infestans.  The fact that the potato was the main food of over half the population of Ireland caused approximately one million people to die as a consequence. 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. Susanna Maiolo (born 1984) is a woman with Italian and Swiss citizenship who rushed towards Pope Benedict XVI twice, most recently at Christmas Eve Midnight Mass, 24 December 2009, inside St. Peter's Basilica in the Vatican.  She knocked the Pope and French cardinal Roger Etchegaray to the ground, and broke the cardinal's leg and hip.  Maiolo's previous attack in December 2008 was intercepted successfully by the Pope's bodyguards. Drug corridor is the name given to various paths in the U.S., generally being coterminal with major highways and interstates, that are major highways for the flow of illicit drugs into, out of, and across the U.S.  There is no definitive drug corridor, as many people claim that their city lies in a drug corridor (just as many people claim that their city is the "meth capital of the world").  Many sources, however, corroborate that the main arteries of drug flow are east–west across the U.S., North from Mexico, and South from Canada.  Most of the marijuana and cocaine imported into the U.S. flows from Latin America across the U.S.–Mexican border, while many imported synthetic drugs and former designer drugs flow south from Canada. 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.
