[EX Q]: 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

[EX Q]: Context: When a new moon passes directly between the Earth and the Sun, it causes a solar eclipse (Figure 24.20). The Moon casts a shadow on the Earth and blocks our view of the Sun. This happens only all three are lined up and in the same plane. This plane is called the ecliptic. The ecliptic is the plane of Earths orbit around the Sun. The Moons shadow has two distinct parts. The umbra is the inner, cone-shaped part of the shadow. It is the part in which all of the light has been blocked. The penumbra is the outer part of Moons shadow. It is where the light is only partially blocked. When the Moons shadow completely blocks the Sun, it is a total solar eclipse (Figure 24.21). If only part of the Sun is out of view, it is a partial solar eclipse. Solar eclipses are rare events. They usually only last a few minutes. That is because the Moons shadow only covers a very small area on Earth and Earth is turning very rapidly. Solar eclipses are amazing to experience. It appears like night only strange. Birds may sing as they do at dusk. Stars become visible in the sky and it gets colder outside. Unlike at night, the Sun is out. So during a solar eclipse, its easy to see the Suns corona and solar prominences. This NASA page will inform you on when solar eclipses are expected: [Link] Sometimes a full moon moves through Earths shadow. This is a lunar eclipse (Figure 24.22). During a total lunar eclipse, the Moon travels completely in Earths umbra. During a partial lunar eclipse, only a portion of the Moon enters Earths umbra. When the Moon passes through Earths penumbra, it is a penumbral eclipse. Since Earths shadow is large, a lunar eclipse lasts for hours. Anyone with a view of the Moon can see a lunar eclipse. Partial lunar eclipses occur at least twice a year, but total lunar eclipses are less common. The Moon glows with a dull red coloring during a total lunar eclipse. The Moon does not produce any light of its own. It only reflects light from the Sun. As the Moon moves around the Earth, we see different parts of the Moon lit up by the Sun. This causes the phases of the Moon. As the Moon revolves around Earth, it changes from fully lit to completely dark and back again. A full moon occurs when the whole side facing Earth is lit. This happens when Earth is between the Moon and the Sun. About one week later, the Moon enters the quarter-moon phase. Only half of the Moons lit surface is visible from Earth, so it appears as a half circle. When the Moon moves between Earth and the Sun, the side facing Earth is completely dark. This is called the new moon phase. Sometimes you can just barely make out the outline of the new moon in the sky. This is because some sunlight reflects off the Earth and hits the Moon. Before and after the quarter-moon phases are the gibbous and crescent phases. During the crescent moon phase, the Moon is less than half lit. It is seen as only a sliver or crescent shape. During the gibbous moon phase, the Moon is more than half lit. It is not full. The Moon undergoes a complete cycle of phases about every 29.5 days.
