[EX Q]: Context: The movie opens with the Barden Bellas about to perform at the ICCA championships. One of them, Chloe (Brittany Snow) is running late to the start of the performance. When she arrives she is reprimanded by the older Bellas. As they are about to perform, Aubrey (Anna Camp) tries to assure them she'll do a good job, but is shot down. The group sings 'The Sign'.. and all is going well, until the very end when Aubrey has a solo, and projectile vomits all over the stage and front rows of the audience.Cut to the start of a new year at Barden University, and freshman Beca (Anna Kendrick) is arriving by taxi. While she is receiving directions and her Rape Whistle, a car passes her by, and another student, Jesse (Skylar Austin) is singing along to the radio, and catches her attention.Beca finds her new dorm room, and meets her roommate Kimmy-Jin, who is hostile and unfriendly. Beca's dad, a professor at Barden then arrives, and asks her how she got there. It is revealed that Beca's parents have split up as she refers to her dad's new wife as her 'step monster', and seems very reluctant to be attending College. Beca's dad tries to encourage her to enjoy it, but Beca escapes to the Activities fair.In another dorm room, Jesse is meeting his roommate Benji (Ben Platt), who is into Star Wars and magic.At the Activities fair, we are introduced to the Trebles - one of the Campus singing groups, all male, who are talented and have a high opinion of themselves, especially Bumper (Adam Devine) the lead singer. Jesse and Benji approach the Trebles, as Benji is desperate to join, but Bumper is not impressed with his enthusiasm.Across the campus, the Bellas are now down to just 2 members - Aubrey and Chloe, who are trying to recruit new ones. Due to their disastrous performance at the last Championships, they are not having much luck, and are even ridiculed by 'Baloney Barb' who has tried out for them previously. They are then approached by Fat Amy (Rebel Wilson), an outgoing and quirky student from Tasmania who doesn't hesitate to demonstrate her singing and dancing abilities. They then meet Beca, who quickly rebuffs their offer to audition, saying it is lame, which immediately puts Aubrey offside.Instead of being interested in joining any of the singing groups, Beca has much more of an interest in remixing music on her laptop. She gets a job at the campus radio station, and much to her dismay, so does Jesse.Her dad pays her a visit in her dorm, and gives her an ultimatum - if she makes an effort and joins a group at College , but still doesn't like it by the end of the year, she can quit and follow her true dream of becoming a DJ, and he will help her... but he wants her to really make an effort.As Beca goes into the communal showers singing to herself, Chloe happens to be in the showers as well, and confronts Beca in her shower stall , insisting that she try out for the Bellas. Although Beca is mortified, she sings along with Chloe to 'Titanium'.Finally the auditions are on, and Jesse, Benji and Fat Amy are among the hopefuls trying out, auditioning to 'Since you've been gone'. Beca comes late, and hasn't prepared the audition song, but auditions with 'Cups (miss me when I'm gone)', and Chloe and Jesse are impressed, while Aubrey is unsure. We then see the initiation of the new Bellas including Beca, Fat Amy, Stacie (Alexis Knapp), Cynthia-Rose (Esther Dean) and the very softly spoken Lilly (Hana Mae Lee). They all swear an oath and drink the 'blood of the Bellas who came before them' (wine). Cut to the initiation of the new Trebles.. Jesse has made it, but Benji has not. That night, there is Aca-initiation where all the groups

[EX Q]: Context: Energy levels (also called electron shells) are fixed distances from the nucleus of an atom where electrons may be found. Electrons are tiny, negatively charged particles in an atom that move around the positive nucleus at the center. Energy levels are a little like the steps of a staircase. You can stand on one step or another but not in between the steps. The same goes for electrons. They can occupy one energy level or another but not the space between energy levels. The model in the Figure 1.1 shows the first four energy levels of an atom. Electrons in energy level I (also called energy level K) have the least amount of energy. As you go farther from the nucleus, electrons at higher levels have more energy, and their energy increases by a fixed, discrete amount. Electrons can jump from a lower to the next higher energy level if they absorb this amount of energy. Conversely, if electrons jump from a higher to a lower energy level, they give off energy, often in the form of light. This explains the fireworks pictured above. When the fireworks explode, electrons gain energy and jump to higher energy levels. When they jump back to their original energy levels, they release the energy as light. Different atoms have different arrangements of electrons, so they give off light of different colors. Q: In the atomic model Figure 1.1, where would you find electrons that have the most energy? A: Electrons with the most energy would be found in energy level IV. The smallest atoms are hydrogen atoms. They have just one electron orbiting the nucleus. That one electron is in the first energy level. Bigger atoms have more electrons. Electrons are always added to the lowest energy level first until it has the maximum number of electrons possible. Then electrons are added to the next higher energy level until that level is full, and so on. How many electrons can a given energy level hold? The maximum numbers of electrons possible for the first four energy levels are shown in the Figure 1.1. For example, energy level I can hold a maximum of two electrons, and energy level II can hold a maximum of eight electrons. The maximum number depends on the number of orbitals at a given energy level. An orbital is a volume of space within an atom where an electron is most likely to be found. As you can see by the images in the Figure 1.2, some orbitals are shaped like spheres (S orbitals) and some are shaped like dumbbells (P orbitals). There are other types of orbitals as well. Regardless of its shape, each orbital can hold a maximum of two electrons. Energy level I has just one orbital, so two electrons will fill this energy level. Energy level II has four orbitals, so it takes eight electrons to fill this energy level. Q: Energy level III can hold a maximum of 18 electrons. How many orbitals does this energy level have? A: At two electrons per orbital, this energy level must have nine orbitals. Electrons in the outermost energy level of an atom have a special significance. These electrons are called valence electrons, and they determine many of the properties of an atom. An atom is most stable if its outermost energy level contains as many electrons as it can hold. For example, helium has two electrons, both in the first energy level. This energy level can hold only two electrons, so heliums only energy level is full. This makes helium a very stable element. In other words, its atoms are unlikely to react with other atoms. Consider the elements fluorine and lithium, modeled in the Figure 1.3. Fluorine has seven of eight possible electrons in its outermost energy level, which is energy level II. It would be more stable if it had one more electron because this would fill its outermost energy level. Lithium, on the other hand, has just one of eight possible electrons in its outermost energy level (also energy level II). It would be more stable if it had one less electron because it would have a full outer energy level (now energy level I). Both fluorine and lithium are

[EX Q]: Context: Playing basketball isn't ladylike. That's what Jewell Chapman's high school headmaster told her in 1961 when he was against the girls' basketball program. "We were very discouraged, " said Chapman, a forward for her high school team of Des Moines. Nearly 50 years later, Chapman is back on the playground. She's 62 and plays for "Hot Pink Grannies", joining about 10 other women on a team whose uniforms are black trousers and hot pink socks. They play in the Iowa Granny Basketball League. It's one of dozens of basketball leagues for women over 50 that have arisen across the country. For some, it's a chance to exercise and meet people; for others, _ "You see more and more elderly women's teams taking part in state and national competitions," said Michael Rogers, a professor in sports studies at Wichita State University. "In the future it will be something common to have leagues like this." Yearly surveys by the National Sporting Goods Association show the number of women aged 55 and older who play basketball at least 50 times a year has grown from 16,000 in 1995 to nearly 131,000 ten years later. The women on the Hot Pink Grannies are good - natured but competitive when game time comes. "I think I'm tough" says Colleen Pulliam, 69, showing off her strong arms at her challengers in a game against "Strutters", known for their bright yellow socks. Granny Basketball Leagues and similar groups spread quickly through much of the country, including California, Louisiana, New Mexico, Pennsylvania and Washington, D.C.
