Context: The Conquest of Melilla occurred in September 1497, when a fleet sent by the Duke of Medina Sidonia seized the north African city of Melilla., as continuation of Reconquest of Mauritania Tingitana During the 15th century the mediterranean cities of the Sultanate of Fez fell in decadence in opposition to cities located in the Atlantic facade, which concentrated most of the economic activity. By the end of the 15th century, the port of Melilla, that had been often disputed between the rulers of Fez and Tlemcen, was nearly abandoned. Plans for the conquest occurred as soon as the Fall of Granada in 1492. Spanish captains Lezcano and Lorenzo Zafra visited the coast of Northern Africa to identify possible locations for the Spanish to overtake, and Melilla was identified as a prime candidate. Melilla was, however, in the Portuguese zone of influence under the terms of the 1479 Treaty of Alcacovaz. At Tordesillas in 1494, King John II of Portugal, the Portuguese ruler agreed to make an exception and permitted the Spanish to attempt the conquest of Melilla. The duke sent Pedro Estopinan who conquered the city virtually without a fight in 1497, as internal conflicts had depleted it of troops, and its defenses were weakened. The Wattasid ruler Muhammad al-Shaykh sent a detachment of cavalrymen to retake control of the city, but they were repulsed by the guns of the Spanish ships. 
 Question: Which happened first, the fleet being sent by the Duke of Medina, or the Conquest of Melilla?

Ex Output:
fleet sent by the duke

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 
 Question: any atom is most stable when its outermost energy level contains

Context: Vanessa Snyder (Alexa Vega) is an admired eighth-grader in her school. She has a loving single mother, Barbara (Lisa Vidal), who is proud of her well-placed daughter. Vanessa is also "in" with the popular clique, led by her best friend Stacy Larson (Leah Pipes), the queen bee, and Nikki Rodriguez (Elizabeth Rice), who is secretly jealous of Stacy and Vanessa's closeness. On the exterior of this exclusive friendship circle is the outsider, Emily (Shari Dyon Perry), and the wannabe, Tiffany (Alicia Morton), who is dying to make it into the pack.The nightmare begins when Nikki tricks Vanessa into getting close to Tony (Chad Biagini), a boy whom Stacy (and somewhat Vanessa) has a crush on. A web of lies, nasty rumors, and manipulation ensues, and Vanessa is ostracized by the clique for "backstabbing" Stacy. Helpless, Vanessa soon faces the conflict and violence from her former friends and other popular girls whom she doesn't even know. Nikki gets Tiffany accepted into the clique, and Tiffany becomes Nikki's sidekick at poisoning the others against Vanessa. Although Nikki is the main girl who is tormenting Vanessa, Stacy plays her part by pretending she's still Vanessa's best friend and not stopping the attacks on her. Vanessa is slowly pushed out of class activities, called names, socially isolated and worst of all, her tormentors create a webpage about her on which they put humiliating photos of Vanessa, along with expressions of hatred towards her.Emily tries to convince Vanessa not to go running back to the clique, but Vanessa keeps attempting to seek reconciliation with Stacy, to disastrous results. The bullying escalates, with Stacy, Nikki, Tiffany and others cornering Vanessa inside a bathroom and verbally brutalizing her, including degrading every aspect of her and revealing her embarrassing secrets. That night, Vanessa has a nervous breakdown and chops all her hair off. Then she starts skipping school, fearing the agony in the hallways. Stacy offers a fake truce to Vanessa and asks for help on an assignment. Vanessa sends Stacy her paper, only to have Stacy copy it and make it look like Vanessa copied Stacy's paper.Once Vanessa shows her mother a print-out of comments about Vanessa's hair, Barbara tries to help by informing the school about the bullying, to no avail as the principal is unable to take disciplinary action against non-physical bullying. Barbara even tries to talk to Stacy's mother, Denise (Rhoda Griffis) but only ends up straining their friendship. Even an adult like Barbara is helpless in the face of teen violence.Vanessa's spirits are suddenly lifted when Stacy invites her to her birthday party. After preparing, she arrives at a club, which is not the site of the party. When discovering this, Vanessa goes ballistic. She takes an overdose of her mother's sleeping pills, but survives and just passes out.In the hospital, Barbara reveals to her daughter that she was also emotionally bullied when she was a teenager, which caused her to encourage Vanessa to stay friends with Stacy. She says that she never dealt with it herself and wished Vanessa would learn self-defense.During a class session, Emily accuses Stacy of nearly killing Vanessa for her actions. She is also the only one of Vanessa's classmates to visit her in the hospital and befriends her.Back home, Barbara spots malicious instant messages popping up on Vanessa's computer and sends them to the school principal. The culprits have been revealed to be Nikki, Tiffany, and Ezra (Joey Nappo), another tormentor. If they deny that they cyber-bullied Vanessa, they would be expelled from the school and not graduate. When Vanessa returns to school, she and Stacy reunite after Stacy convinces her that she's sorry about the bullying. They IM each other about how great it feels to be best friends again. Then graduation day comes and the final conflict happens when after the graduation, Nikki and Tiffany read aloud the chat between Vanessa and Stacy, which Stacey had sent to Nikki, and which Nikki had printed out. 
 Question: Who is considered Stacy's "henchwomen"?
