question:
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?
answer:
archaea


question:
Context: Ant & Dec are an English comedy TV presenting duo, consisting of Anthony McPartlin OBE and Declan Donnelly OBE , from Newcastle upon Tyne, England. Formed after their meeting as actors on CBBC's drama, Byker Grove, the duo have led successful careers as television presenters, with hosting credits including SMTV Live, CD:UK, Friends Like These, Pop Idol, Ant & Dec's Saturday Night Takeaway, I'm a Celebrity...Get Me Out of Here!, PokerFace, Push the Button, Britain's Got Talent, Red or Black?, and Text Santa. Due to a difference in height - Ant being the taller at 5ft 8in , and Dec being two inches shorter at 5ft 6in - the pair identify themselves in the media by adopting the use of the 180-degree rule, with the exception of some early publicity shots. In addition to presenting, the duo are accomplished actors - both had leading roles in the 2006 film Alien Autopsy - operate as television producers - they own their own production company, Mitre Television - have presented the annual Brit Awards in 2001, 2015 and 2016, and are former pop musicians who operated under the aliases of their characters from Byker Grove. In a 2004 poll for the BBC, Ant & Dec were named the eighteenth most influential people in British culture. 
 Question: Who is the "Dec" in "Ant & Dec"?
answer:

question:
Context: Anna Foster (Mandy Moore) is the daughter of the President of the United States, James (Mark Harmon) and First Lady Michelle Foster (Caroline Goodall).When a hassle of Secret Service agents ruins a first date, Anna demands some freedom. Her dad agrees to send only two agents with Anna and Gabrielle La Clare (Beatrice Rosen) to a concert when Anna goes to Prague with her parents. A sexy new look for Anna causes her father to renege. When Anna discovers the concert is filled with agents and that her father has broken his promise, Gabrielle helps Anna elude her protectors. Outside the concert, Anna meets Ben Calder (Matthew Goode), and asks him to drive her to escape the agents. Anna goes to a bar with Ben and proceeds to get drunk. Unbeknownst to Anna, Ben is with the Secret Service, and tells agents Alan Weiss (Jeremy Piven) and Cynthia Morales (Annabella Sciorra) where Anna is. The President orders the three agents to have Ben guard Anna without telling her who he really is, to give her an illusion of freedom with a guarantee of safety. Believing herself free of her guards for the first time in years, Anna jumps into the Vltava River naked, mistaking it for the Danube, and Ben has to fish her out (he stays clothed). Weiss and Morales buy the camera from someone taking pictures of the skinny-dipping Anna. Anna and Ben climb a rooftop to watch an opera being shown in a plaza, where Anna eventually falls asleep with Ben guarding her, and Weiss and Morales watching from another roof.The next morning, Anna calls her parents to avoid getting into further trouble with them. Knowing she is safe, her father is initially indulgent, and Anna is about to return, but his tone changes when he is shown the photos of her nude in the river. The First Lady, however, asks, "What happened to 'let freedom ring?'" (That had been his earlier line when he had decided to let her stay out with Ben.) Anna is outraged at both her dad's sudden imperious tone and finding out that he traced her call. She decides to meet Gabrielle at the Love Parade in Berlin and return to her parents right before the plane trip home. Ben goes with her on the train, where they meet Scotty McGruff (Martin Hancock), a flighty romantic obsessed with Six Million Dollar Man stickers and the interconnectivity of the world, he gives them a stack of stickers and tells them to stick them up in random places, then one day when they are unhappy, they will see one and it will make them smile. Through him, the two learn that they have boarded a Venice-bound train. When they arrive in Venice, Ben calls the other agents to tell them where they are but has to leave the phone dangling when he realizes he can no longer see Anna. He finds her and McGruff getting new clothes, and the three explore Venice - until McGruff steals their wallets. Ben is about to tell the cafe they cannot pay when Anna is recognized and races off to avoid being identified as the First Daughter. Ben follows, and they tell a story of marrying, against the wishes of Anna's parents, to get a gondola ride from a kind-hearted gondolier, Eugenio (Joseph Long). Ben kisses Anna during the ride to hide her from the cafe staff's sight. Since they have no place to stay, Eugenio invites them to his and his mother Maria's (Miriam Margolyes) house. That night, thinking the kiss meant that Ben cares for her, Anna offers herself to him. To dissuade her, Ben is disingenuous and harsh. Anna finally gets in the bed alone, while Ben lies on the floor.The next day, Eugenio drives them to the Austrian border, as Weiss and Morales show up at Maria's looking for the gondolier with whom Anna and Ben were last seen. Maria tells them that Anna and Ben are married, which is reported to Anna's parents. Upset that Ben rejected her, Anna gets a ride on a truck, leaving Ben to
