Given a question and a context passage, generate the answer having the word or phrase from the context passage. Here, the answer should be a shortest continous span from the passage.

Example Input: Context: How quickly is the human population growing? If we look at worldwide human population growth from 10,000 BCE through today, our growth looks like exponential growth. It increased very slowly at first, but later grew faster and faster as the population increased in size ( Figure 1.1). And recently, the human population has increased at a faster pace than ever before. It has taken only 12 years for the worlds population to increase from six billion to seven billion. Considering that in the year 1804, there were just one billion people, and in 1927, there were just two billion people (thats 123 years to increase from 1 to 2 billion), the recent increase in the human population growth rate is characteristic of exponential growth. Does this mean there are unlimited resources? Worldwide human population growth from 10,000 BCE through today. On the other hand, if you look at human population growth in specific countries, you may see a different pattern. On the level of a country, the history of human population growth can be divided into five stages, as described in Table 1.1. Some countries have very high birth rates, in some countries the growth rate has stabilized, and in some countries the growth rate is in decline. Stage 1 2 3 4 5 Description Birth and death rates are high and population growth is stable. This occurred in early human history. Significant drop in death rate, resulting in exponential growth. This occurred in 18th- and 19th-century Eu- rope. Population size continues to grow. Birth rates equal death rates and populations become stable. Total population size may level off. The United Nations and the U.S. Census Bureau predict that by 2050, the Earth will be populated by 9.4 billion people. Other estimates predict 10 to 11 billion. There are two different beliefs about what type of growth the human population will undergo in the future: 1. Neo-Malthusians believe that human population growth cannot continue without destroying the environment, and maybe humans themselves. 2. Cornucopians believe that the Earth can give humans a limitless amount of resources. They also believe that technology can solve problems caused by limited resources, such as lack of food. The Cornucopians believe that a larger population is good for technology and innovation. The 5-stage model above predicts that when all countries are industrialized, the human population will eventually level out. But many scientists and other Neo-Malthusians believe that humans have already gone over the Earths carrying capacity. That means, we may have already reached the maximum population size that can be supported, without destroying our resources and habitat. If this is true, then human overpopulation will lead to a lack of food and other resources. Overpopulation may also lead to increased disease, and/or war. These problems may cause the population of humans to crash. If these issues are not controlled, could the human population go extinct? Which of the above theories makes sense to you? Why? 
 Question: which is the last stage of human population growth?
Example Output: total population size may level off.

Example Input: Context: In 2092, humanity has conquered mortality through the endless renewal of cells. The world watches in fascination as the 118-year-old Nemo Nobody, the last mortal on Earth, edges towards death. Curious to know of life before quasi-immortality, they interview Nemo. Dr. Feldheim, a psychiatrist, uses hypnosis to help Nemo recall some of his memories, while Nemo relates other memories to a journalist. As he is prodded, Nemo makes contradictory statements. He recounts his life at three primary points: at age 9, when his parents divorced, at age 15 when he fell in love, and at age 34 as an adult. All three unfold into their many possible outcomes. Nemo explains that before birth, children remember everything that will happen in their lives. At the moment of conception, the Angels of Oblivion erase their memory. The Angels, however, forget about Nemo, allowing him to "remember" different possible futures for himself. At age 9, at a railway station, he is forced to choose as his mother leaves on a train while his father stays on the platform. In one case, he manages to board the train while in another he stays with his father. Life with mother[edit] A rebellious Nemo lives with his mother and her new partner, Harry, in Montreal. He sees a new girl, Anna, in his school and is immediately smitten. One day on the beach, Anna asks if he would like to swim with her and her friends. Nemo insults her friends and they barely see each other again. In an alternate story line, Nemo admits to Anna he cannot swim; the two spend time together and fall in love. Anna turns out to be Harry's daughter and the two step siblings begin an illicit affair. They pledge their lives to one another. When Harry and Nemo's mother break up, Anna goes to New York with her father, and they lose touch. Years later, Nemo works as a pool cleaner, hoping to run into Anna by chance. They finally see one another at the train station and immediately recognize each other in a crowd of passers-by. After a passionate reunion, Anna announces she is not ready to immediately resume the relationship. She gives him her number, asks him to call her in two days and meet at the lighthouse. However, he loses her number when a sudden downpour makes her note illegible. Nemo waits at the lighthouse every day, but Anna does not come. In a different storyline, Anna and Nemo are married with children. Nemo works at a television studio narrating educational videos. One evening, while returning home, he hits a bird, loses control of his car, plummets into a lake and drowns. Life with father[edit] Nemo stays with his father, who later becomes disabled. He works in a shop and spends his free time at home at the typewriter, writing a science fiction story about a journey to Mars. At a school dance, he meets Elise and falls in love. A few days later, Nemo goes to Elise's house but sees her with her 22-year-old boyfriend. Frustrated, he speeds away on his motorcycle, has an accident and is hospitalized in a vegetative state. Though he can perceive the world through his senses, Nemo cannot move or speak. He detects his parents' reunion at his bedside. Nemo tries to remember the movement of his fingers on the typewriter keyboard and eventually manages to lift a finger as this story line comes to a close. In yet another alternate timeline, Nemo speaks with Elise at her house, and learns that she is still in love with her boyfriend, Stefano. Nemo does not back down and keeps assuring her of his feelings. Finally, Elise gives in and a few years later, they get married. In one version of the story line, Elise dies in an accident on the return from the wedding. Nemo keeps her ashes, having promised her to spread them on Mars. In a far future, Nemo carries Elise's ash to Mars and spreads them on the planet's surface. Aboard the
