Context: One day Mr. White gave his wife ten pounds for her birthday -- ten new pound notes. So Mrs. White went out shopping. She waited for a bus, got on it and sat down next to an o1d 1ady. After a while, Mrs. White noticed that the old 1ady's handbag was open. Inside it, she saw a wad of pound notes exactly like the ones her husband had given her. So she quickly looked into her own bag -- the notes had gone! Mrs. White was sure that the o1d lady next to her had stolen them. She immediately thought of calling the police. But as she disliked making a fuss , she decided to take back the money from the old 1ady's hand bag and say nothing about it. She looked around to make sure nobody was watching. Then she carefully put her hand into the o1d lady's bag, took the notes, and put them into her own handbag. When she got home that evening, Mrs. White showed her husband the beautiful hat she had bought. "How did you pay for it?" Mr. White asked. "With the money you gave me for my birthday, of course" she answered. "Oh? What's that, then?" he asked, as he pointed to a wad of pound notes on the table.
Question: What did Mrs. White use the money given by her husband for?

nothing.

Context: at the Georgia Dome, Atlanta, Georgia Trying to end a three-game skid, the Falcons returned home for an NFC South rematch with the New Orleans Saints. From the get-go, the Falcons trailed as in the first quarter, QB Drew Brees completed a 76-yard TD pass to WR Devery Henderson, while RB Deuce McAllister got a 1-yard TD run. Atlanta would respond with kicker Morten Andersen kicking a 22-yard field goal. In the second quarter, Andersen gave the Falcons a 30-yard field goal, yet New Orleans continued dominating with Brees completing an incredible 48-yard TD pass to WR Terrance Copper on the very last offensive play of the half. In the third quarter, RB Warrick Dunn gave Atlanta some room to operate, as he a 1-yard TD run for the only score of the half. However, in the fourth quarter, the Saints wrapped up the game with kicker John Carney getting a 25-yard field goal, while McAllister got a 9-yard TD run. After the game, as QB Michael Vick was leaving the field, he flicked off an insulting fan with both hands. He was fined $10,000 from the NFL and had to donate another $10,000 to charity. With their fourth-straight loss, the Falcons fell to 5-6.
Question: Who scored first

Ex Output:
saints

Context: If pathogens get through the bodys first two lines of defense, a third line of defense takes over. This third line of defense involves the immune system. It is called an immune response, and is a specific type of response. The immune system has a special response for each type of pathogen. The immune system ( Figure 1.1) is also part of the lymphatic systemnamed for lymphocytes, which are the type of white blood cells involved in an immune response. They include several lymph organs, lymph vessels, lymph, and lymph nodes. This diagram shows the parts of the im- mune system. The immune system in- cludes several organs and a system of vessels that carry lymph. Lymph nodes are located along the lymph vessels. The lymph organs are the red bone marrow, tonsils, spleen, and thymus gland. They are described below ( Figure Each lymph organ has a different job in the immune system. Lymph vessels make up a circulatory system that is similar to the cardiovascular system, which you can read about in a previous concept. Lymph vessels are like blood vessels, except they move lymph instead of blood. Lymph is a yellowish liquid that leaks out of tiny blood vessels into spaces between cells in tissues. Where there is more inflammation, there is usually more lymph in tissues. This lymph may contain many pathogens. The lymph that collects in tissues slowly passes into tiny lymph vessels. It then travels from smaller to larger lymph vessels. Lymph is not pumped through lymph vessels like blood is pumped through blood vessels by the heart. Instead, muscles around the lymph vessels contract and squeeze the lymph through the vessels. The lymph vessels also contract to help move the lymph along. The lymph finally reaches the main lymph vessels in the chest. Here, the lymph drains into two large veins. This is how the lymph returns to the bloodstream. Before lymph reaches the bloodstream, pathogens are removed from it at lymph nodes. Lymph nodes are small, oval structures located along the lymph vessels. They act like filters. Any pathogens filtered out of the lymph at lymph nodes are destroyed by lymphocytes in the nodes. Lymphocytes ( Figure 1.3), a type of white blood cell, are the key cells of an immune response. There are trillions of lymphocytes in the human body. They make up about one quarter of all white blood cells. Usually, fewer than half of the bodys lymphocytes are in the blood. The rest are in the lymph, lymph nodes, and lymph organs. There are two main types of lymphocytes: 1. B cells. This image of a lymphocyte was made with an electron microscope. The lym- phocyte is shown 10,000 times its actual size. 2. T cells. Both types of lymphocytes are produced in the red bone marrow. They are named for the sites where they grow larger. The "B" in B cells stands for bone. B cells grow larger in red bone marrow. The "T" in T cells stands for thymus. T cells mature in the thymus gland. B and T cells must be switched on in order to fight a specific pathogen. Once this happens, they produce an army of cells ready to fight that particular pathogen. How can B and T cells recognize specific pathogens? Pathogens have proteins, often located on their cell surface. These proteins are called antigens. An antigen is any protein that causes an immune response, because it is unlike any protein that the body makes. Antigens are found on bacteria, viruses, and other pathogens. Your body sees these as foreign, meaning they do not belong in your body.

Ex Output:
thymus gland.
