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: When reporter ANN MITCHELL is laid off by managing editor HENRY CONNELL because of streamlining, she begs to stay on since she's supporting her MOTHER and TWO SISTERS, but it's no use. Angry, she gathers up her belongings but then, as a parting shot, types up a fake letter from "John Doe" stating that he's so downtrodden by the unfairness of things that he intends jumping off the building on Christmas Eve.The paper prints the letter and it causes a sensation. Everyone relates to and wants to help John Doe. Connell, desperate to get hold of the original letter is shocked when Ann tells him there was no letter. Connell, angry, is ready to print a retraction but Ann suggests that they hire a "fake John Doe" to embody the pathos of the letter. She gets her job back along with a lucrative fee and contract.Several desperate MEN line up claming to have written the letter, so Ann and Connell must now pick the one. When handsome JOHN WILLOUGHBY walks in, Ann's clearly smitten. A likeable, quiet baseball player who's fallen on bad times, John's the one who will become "John Doe." Although he seems too honest to lie, Ann believes he's desperate enough. They create a fake letter, put him up at a fancy hotel with bodyguards, making him sign an agreement. Also in tow (much to Connell's chagrin) is THE COLONEL, a confirmed vagabond, distrustful of society, who warns John that he's falling into a trap of privilege.Next come publicity photos, which are directed by Ann to get the correct "angry protest" look. With headlines proclaiming his anger at the unfairness of the world, John becomes an increasing media sensation, courtesy of hyperbolic headlines concocted by Connell. Meanwhile, the GOVERNOR suspects John Doe is a myth but mistakenly feels it was concocted by publisher B. D. NORTON to discredit him. Ann convinces Norton to play it for what it's worth. Norton offers her money to write radio speeches to sell Doe. He also wants her to work directly with him and not Connell.Ann goes to work, typing up a storm but nothing comes to mind. Ann's Mother suggests that she write something upbeat and simple, using the values of Ann's late father as an inspiration. By now, John has begun realizing that his baseball career might not get started again if the John Doe business is revealed as a phony.Nonetheless, John reads his first manufactured upbeat speech, written by Ann to a packed house. Ann coaches him to be sincere, suggesting that she's fallen in love with John Doe. The speech, broadcast on the radio, stirs the people with its "love thy neighbor"-style message. CROWDS love him but John can't get away fast enough. He and the Colonel resort to the boxcars and flee. B. D. Norton, thinking he was great, wants him located.When a DINER WAITER recognizes him, John's hope for a return to normalcy is squelched by sudden CROWDS, eager to meet him. Ann and Norton locate him. John isn't happy about it. When Norton offers him a lecture tour, he refuses it angrily. When the common PEOPLE who have a "John Doe" club talk to him, however, he softens when hearing how he's touched them. Now, John's torn. His itinerant pal, The Colonel, thinks he's been "hooked" and, disgusted, walks out on him.Norton arranges the lecture tour. John speaks in state after state, addressing the many national clubs in his name. Connell tells Norton, however, that he's curious why Norton is spending so much money on the tour. In the meantime, Ann, knowing that John now likes her, feels increasingly like the heel she feels she is. She feels even worse when John relates a tender dream that he had about her and talks to her about how he relates to the lonely, hungry people to whom he's been speaking.Norton gives Ann a fur coat and a gift. He then tells her that he wants John Doe to announce a

Example Input: Context: So that people in developed nations maintain a good lifestyle and people in developing nations have the ability to improve their lifestyles, natural resources must be conserved and protected (Figure 1.1). People are researching ways to find renewable alternatives to non-renewable resources. Here is a checklist of ways to conserve resources: Buy less stuff (use items as long as you can, and ask yourself if you really need something new). Reduce excess packaging (drink tap water instead of water from plastic bottles). Recycle materials such as metal cans, old cell phones, and plastic bottles. Purchase products made from recycled materials. Reduce pollution so that resources are maintained. Prevent soil erosion. Plant new trees to replace those that are cut down. Drive cars less, take public transportation, bicycle, or walk. Conserve energy at home (turn out lights when they are not needed). Click image to the left or use the URL below.

 Question: which one of these can you not recycle
Example Output: trees

Example Input: Context: Mendeleev was a teacher as well as a chemist. He was writing a chemistry textbook and needed a way to organize the elements so it would be easier for students to learn about them. He made a set of cards of the elements, similar to a deck of playing cards, with one element per card. On the card, he wrote the elements name, atomic mass, and known properties. He arranged and rearranged the cards in many different ways, looking for a pattern. He finally found it when he placed the elements in order by atomic mass. You can see how Mendeleev organized the elements in Figure 6.2. From left to right across each row, elements are arranged by increasing atomic mass. Mendeleev discovered that if he placed eight elements in each row and then continued on to the next row, the columns of the table would contain elements with similar properties. He called the columns groups. They are sometimes called families, because elements within a group are similar but not identical to one another, like people in a family. Mendeleevs table of the elements is called a periodic table because of its repeating pattern. Anything that keeps repeating is referred to as periodic. Other examples of things that are periodic include the monthly phases of the moon and the daily cycle of night and day. The term period refers to the interval between repetitions. In a periodic table, the periods are the rows of the table. In Mendeleevs table, each period contains eight elements, and then the pattern repeats in the next row. Did you notice the blanks in Mendeleevs table (Figure 6.2)? They are spaces that Mendeleev left for elements that had not yet been discovered when he created his table. He predicted that these missing elements would eventually be discovered. Based on their position in the table, he could even predict their properties. For example, he predicted a missing element in row 5 of his group 3. He said it would have an atomic mass of about 68 and be a soft metal like other group 3 elements. Scientists searched for the missing element. They found it a few years later and named it gallium. Scientists searched for the other missing elements. Eventually, all of them were found. An important measure of a good model is its ability to make accurate predictions. This makes it a useful model. Clearly, Mendeleevs periodic table was a useful model. It helped scientists discover new elements and make sense of those that were already known. A periodic table is still used today to classify the elements. Figure 6.3 shows the modern periodic table. You can see an interactive version at this URL: . In the modern periodic table, elements are organized by atomic number. The atomic number is the number of protons in an atom of an element. This number is unique for each element, so it seems like an obvious way to organize the elements. (Mendeleev used atomic mass instead of atomic number because protons had not yet been discovered when he made his table.) In the modern table, atomic number increases from left to right across each period. It also increases from top to bottom within each group. How is this like Mendeleevs table? Besides atomic number, the periodic table includes each elements chemical symbol and class. Some tables include other information as well. The chemical symbol consists of one or two letters that come from the chemicals name in English or another language. The first letter is always written in upper case. The second letter, if there is one, is always written in lower case. For example, the symbol for lead is Pb. It comes from the Latin word plumbum, which means "lead." Find lead in Figure 6.3. What is its atomic number? You can access videos about lead and other elements in the modern periodic table at this URL: . The classes of elements are metals, metalloids, and nonmetals. They are color-coded in the table. Blue stands for metals, orange for metalloids, and green for nonmetals. You can read about each of these three classes of elements later in the chapter, in the lesson "Classes of Elements.
