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: Ian Lafferty (Josh Zuckerman) is an 18-year-old recent high school graduate. He searches for a girl online making it seem as if he is attractive and strong, although he's sweet and unassuming. He soon meets "Ms. Tasty" (Katrina Bowden) and agrees to meet her in person. She lives in Knoxville, Tennessee, while he lives in Chicago, Illinois. With his best friends Lance Nesbitt (Clark Duke) and Felicia Alpine (Amanda Crew), he goes to Knoxville in a 1969 Pontiac GTO Judge borrowed without permission from Ian's arrogant homophobic older brother Rex (James Marsden). On the way to Knoxville, they come across a hitchhiker (David Koechner), as the radiator in the Judge overheats. They attempt urinating in the radiator, which only works briefly as they try to leave the hitchhiker in the dust. The hitchhiker, frustrated at Ian's lack of concern for his well being, leaves, but not before urinating on the car window. As Ian and Felicia wander to find help, Lance is waiting with the car as Ezekiel (Seth Green) happens to pass by in his horse-drawn buggy. Ezekiel and his Amish buddies repair the car while they join a Rumspringa party where Fall Out Boy are playing a concert, and at which Lance meets an attractive Amish girl, Mary (Alice Greczyn). The three promise to come again on the way back to do some work in return for fixing the car. They go to jail due to Ian throwing a tire iron into a state trooper car, due to his increasing frustration after trying to put a possum he hit out of its misery, and are released after Mary pays the bail. Upon arriving at Knoxville, they find a hotel that sports a wide variety of role playing rooms. Rex, who has discovered the Judge gone missing, arrives angrily and insists that they go back and that Ian cannot visit Ms. Tasty. After Ian pretends to be gay, Rex allows him to see Ms. Tasty, hoping this encounter will change Ian's mind. Ian finally meets Ms. Tasty. However, when he tells her about Felicia, her seduction for Ian to take off his clothes becomes a threat as her psychotic boyfriend Bobby Jo (Dave Sheridan) puts a gun to Ian's head. It becomes apparent that they work at a chop shop and attempt to steal the Judge. Lance and Mary arrive after having sex, as well as a redneck named Rick (Michael Cudlitz) whose girlfriend Brandy (Andrea Anders) slept with Lance earlier. Felicia, however, is hiding in the car when Bobby Jo tries to steal it. Soon, a green car that has been continuously drag-racing with the Judge throughout the movie arrives. Ian manages to save Felicia, who then is able to run off and report to the police. Ms. Tasty tries to escape, but is stopped by the green car, whose drivers turn out to be Andy and Randy (Charlie McDermott and Mark L. Young), two dim-witted self-declared "womanizers" from Ian's school, who Ms. Tasty tried to manipulate into giving her the car. Bobby Jo is treated after being shot by Ian in self-defense. Felicia tells the police about the chop shop location and the couple is arrested. Upon finding out that if Mary leaves the Amish community, she will be shunned, Lance refuses to come back home and stays behind to marry Mary, while Ian and Felicia realize their love for each other. Ian and Felicia drive to a tree where Ian throws his shoes up into the tree. A few weeks later Ian is Felicia's date to her cousin's wedding. At Thanksgiving dinner, Rex tells his family that he's gay. On New Year's Eve Ian and Felicia finally have sex, in Ian's basement under a blanket on the sofa. In the final frame of the film, a picture is shown of Lance and Mary getting married, accompanied by Ian. Lance is shown sporting a beard exactly like Ezekiel's. During the credits, a short scene is shown of Ezekiel and Fall Out Boy arguing over the fact that the

Example Input: Context: Lets explore the domain, the least specific category of classification. All of life can be divided into three domains, based on the type of cell of the organism: 1. Bacteria: cells do not contain a nucleus. 2. Archaea: cells do not contain a nucleus; they have a different cell wall from bacteria. 3. Eukarya: cells do contain a nucleus. The Archaea and Bacteria domains ( Figure 1.1) are both entirely composed of small, single-celled organisms and seem very similar, but they also have significant differences. Both are composed of prokaryotic cells, which are cells without a nucleus. In addition, both domains are composed of species that reproduce asexually ( asexual reproduction) by dividing in two. Both domains also have species with cells surrounded by a cell wall, however, the cell walls are made of different materials. Bacterial cell walls contain the polysaccharide peptidoglycan. Lastly, Archaea often live in extreme environments including hot springs, geysers, and salt flats. Bacteria do not live in these environments. The Group A Streptococcus organism (left) is in the domain Bacteria, one of the three domains of life. The Halobacterium (right) is in the domain Archaea, another one of the three domains. All of the cells in the domain Eukarya keep their genetic material, or DNA, inside the nucleus. The domain Eukarya is made up of four kingdoms: 1. Plantae: Plants, such as trees and grasses, survive by capturing energy from the sun, a process called photo- synthesis. 2. Fungi: Fungi, such as mushrooms and molds, survive by "eating" other organisms or the remains of other organisms. These organisms absorb their nutrients from other organisms. 3. Animalia: Animals also survive by eating other organisms or the remains of other organisms. Animals range from tiny ants to the largest whales, and include arthropods, fish, amphibians, reptiles, and mammals ( Figure 4. Protista: Protists are not all descended from a single common ancestor in the way that plants, animals, and fungi are. Protists are all the eukaryotic organisms that do not fit into one of the other three kingdoms. They include many kinds of microscopic one-celled (unicellular) organisms, such as algae and plankton, but also giant seaweeds that can grow to be 200 feet long. Plants, animals, fungi, and protists might seem very different, but remember that if you look through a microscope, you will find similar cells with a membrane-bound nucleus in all of them. These are eukaryotic cells. These cells also have membrane-bound organelles, which prokaryotic cells lack. The main characteristics of the three domains of life are summarized in Table 1.1. Multicelluar Cell wall Nucleus (Membrane- Enclosed DNA) Membrane-Bound Organelles Archaea No Yes, without peptidogly- can Bacteria No Yes, with peptidoglycan No No Eukarya Yes Varies. Plants and fungi have a cell wall; animals do not. Yes No No Yes Diversity of Animals. These photos give just an inkling of the diversity of organisms that belong to the animal kingdom. (A) Sponge, (B) Flatworm, (C) Flying Insect, (D) Frog, (E) Tiger, (F) Gorilla. 
 Question: if you find a single-celled organism living in a geyser, it probably belongs to which domain?
Example Output: archaea
