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: During active transport, molecules move from an area of low concentration to an area of high concentration. This is the opposite of diffusion, and these molecules are said to flow against their concentration gradient. Active transport is called "active" because this type of transport requires energy to move molecules. ATP is the most common source of energy for active transport. As molecules are moving against their concentration gradients, active transport cannot occur without assistance. A carrier protein is always required in this process. Like facilitated diffusion, a protein in the membrane carries the molecules across the membrane, except this protein moves the molecules from a low concentration to a high concentration. These proteins are often called "pumps" because they use energy to pump the molecules across the membrane. There are many cells in your body that use pumps to move molecules. For example, your nerve cells (neurons) would not send messages to your brain unless you had protein pumps moving molecules by active transport. The sodium-potassium pump ( Figure 1.1) is an example of an active transport pump. The sodium-potassium pump uses ATP to move three sodium (Na+ ) ions and two potassium (K+ ) ions to where they are already highly concentrated. Sodium ions move out of the cell, and potassium ions move into the cell. How do these ions then return to their original positions? As the ions now can flow down their concentration gradients, facilitated diffusion returns the ions to their original positions either inside or outside the cell. 
 Question: which statement is true concerning active transport?
Example Output: during active transport, molecules move from an area of low concentration to

Example Input: Context: In late July, Danzig was re-inforced by a Dutch garrison, and a combined Danish and Dutch fleet broke the naval blockage imposed on Danzig by Charles X Gustav. On 28-30 July, a combined Brandenburgian-Swedish army was able to defeat the Polish-Lithuanian army in the Battle of Warsaw, forcing John II Casimir to retreat to Lublin. In August, Alexis' army took Livonian Kokenhausen , laid siege to Riga and Dorpat and raided Estonia, Ingria and Kexholm. On 4 October, John II Casimir stormed eczyca in Greater Poland before heading for Royal Prussia, and on 8 October, Wincenty Korwin Gosiewski with 12,000 to 13,000 Lithuanian and Crimean Tartar cavalry overran a Brandenburgian-Swedish force in the Battle of Prostken in Ducal Prussia. Gosiewski then ravaged Ducal Prussia, burning 13 towns and 250 villages, in a campaign that entered folklore because of the high death toll and the high number of captives deported to the Crimea. On 22 October, Gosiewski was defeated by Swedish forces in the Battle of Filipow and turned to Lithuania. Also on 22 October, besieged Dorpat surrendered to Alexis, while the Russian siege of Swedish-held Riga was lifted. John II Casimir meanwhile took Bromberg and Konitz in Royal Prussia, and from 15 November 1656 until February 1657 stayed in Danzig, where a Swedish siege had to be lifted due to Dutch intervention, just 55 kilometers away from Charles X Gustav's quarters in Elbing. 
 Question: Who won the Battle of Warsaw?
Example Output: brandenburgian-swedish

Example Input: Context: (Because the film has a very complicated plot and features many characters, the events will be told mostly in chronological order to render the plot clearer, rather than strictly adhering to the order we see in the film.)General Sternwood has two daughters: the elder one is Vivian (Lauren Bacall) and the younger one is Carmen, who is a carefree, childish and problematic young woman.General Sternwood has a man named Sean Regan working for him. With the help of Sean, the general has made a man named Joe Brody leave Carmen alone, by giving him 5.000 Dollars.Carmen loves Sean but Sean loves the wife of a man named Eddie Mars, so he refuses Carmens advances. One day, Carmen kills Sean when she is drunk because of her unrequited love. Eddie hides Seans body. He then makes up the story that Sean and his wife have run away together and nobody sees Sean after that day. To support this story, he actually makes his own wife go away and start living in a remote place. Even the general doesnt know Seans whereabouts and wonders why he has left all of a sudden. Eddie then proceeds to blackmail Vivian for Carmens murder. As a way of eliciting money from Vivian, Eddie makes her win big money at his gambling house with cheats, and then he takes all the money from her.Carmens troublesome adventures are not over, though. A man named Arthur Gwynn Geiger blackmails General Sternwood to take the gambling debts of Carmen. The general hires Philip Marlowe (Humphrey Bogart) to get rid of Geigers blackmail. Vivian talks to Marlowe, thinking that her father has actually hired him to find Sean Regan. Afraid that Carmen may get into trouble, she tries to take words from Marlowes mouth about his inquiry. But she learns that her father has not actually hired Marlowe about Sean.Marlowe goes to Geigers so-called antique books shop and sees a woman named Agnes, who makes it impossible for him to talk to Geiger. Then Marlowe waits at the bookshop across the street until the evening and follows Geiger and his right arm Carol Lundgren to Geigers house. Before Marlowe gets in the house, however, important things happen. Owen Taylor, driver for the Sternwoods, is in love with Carmen. He goes to Geigers house with her and kills Geiger for her. A secret camera, however, takes Carmens photo just at the moment of the murder. Owen then takes the film from the hidden camera, gets in the car and goes away. Joe Brody, also present that night, follows Owen, takes the film from him to blackmail Carmen, (and most probably) kills Owen and pushes his car in the water.When Marlowe gets in Geigers house, he sees Carmen with the dead body of Gaiger lying on the ground. Marlowe takes Carmen home and tells Vivian to say that Carmen has been home all night if asked by anyone. When he goes back to Geigers house, he sees that his dead body has been taken away.Later, Owens dead body is found in the car in the water. He has been killed before falling into the water. Marlowe learns from Vivian that Owen was interested in Carmen. Vivian then tells Marlowe that somebody is blackmailing her for Carmens photo taken at the night of Geigers murder. The blackmailer, who wants 5.000 Dollars, is actually Agnes. It is Joe Brody that makes her blackmail Vivian. Vivian tells Marlowe that she can take the money from Eddie.When Marlowe meets with Carmen once again at Geigers house, she tells him that it was Joe who took her photo that night. Eddie comes along and tries to scare Marlowe out of his inquiries.Later, Marlowe finds Joe Brody and questions him about Geiger. Agnes and Vivian are also at his house. Carmen comes along with a gun and threatens to kill Joe if he doesnt give her the photo. Carmen takes the photo and she leaves with Vivian. Then the doorbell rings again and somebody kills Joe, then escapes. Marlowe catches the man, who turns out to be Carol (Geigers right arm), who thinks that it was Joe who killed Geiger. Marlowe and Carol then go to
