Question: Context: Can you name some fossils? How about dinosaur bones or dinosaur footprints? Animal skeletons, teeth, shells, coprolites (otherwise known as feces), or any other remains or traces from a living creature that becomes rock is a fossil. The same processes that formed these fossils also created some of our most important energy resources, fossil fuels. Coal, oil, and natural gas are fossil fuels. Fossil fuels come from living matter starting about 500 million years ago. Millions of years ago, plants used energy from the Sun to form sugars, carbohydrates, and other energy-rich carbon compounds. As plants and animals died, their remains settled on the ground on land and in swamps, lakes, and seas (Figure 1.1). Over time, layer upon layer of these remains accumulated. Eventually, the layers were buried so deeply that they were crushed by an enormous mass of earth. The weight of this earth pressing down on these plant and animal remains created intense heat and pressure. After millions of years of heat and pressure, the material in these layers turned into chemicals called hydrocarbons (Figure 1.2). Hydrocarbons are made of carbon and hydrogen atoms. This molecule with one carbon and four hydrogen atoms is methane. Hydrocarbons can be solid, liquid, or gaseous. The solid form is what we know as coal. The liquid form is petroleum, or crude oil. Natural gas is the gaseous form. The solar energy stored in fossil fuels is a rich source of energy. Although fossil fuels provide very high quality energy, they are non-renewable.

Question: Context: The film opens with an animated prologue revealing the origins of leprechauns, stating that they were summoned by a king to protect his gold from those who would try to steal it. After the death of the king the Leprechauns returned to their places of origin, all except one (Warwick Davis) who remained in the mortal world and through the ages slowly became corrupted and obsessed with the treasure he still guarded. In the present Father Jacob (Willie C. Carpenter) is chased through the construction site of the youth center he had planned on building by the Leprechaun, whose gold Jacob had taken to fund the building project. Using four-leaf clover laced holy water Jacob manages to banish the Leprechaun, summoning demonic hands which drag him underground, but soon after drops dead of injuries inflicted by the Leprechaun during the fight.One year later two down on their luck friends Emily Woodrow (Tangi Miller) and Lisa Duncan (Sherrie Jackson) have their fortune told when the clairvoyant Esmeralda (Donzaleigh Abernathy) who warns them that they will attain great wealth soon, but it must be denied as it will come at a great price and summon a terrible evil. While having a barbecue at the abandoned youth center construction site with Lisa, their stoner friend Jamie Davis (Page Kennedy) and her ex-boyfriend turned drug dealer Rory Jackson (Laz Alonso) Emily falls through a hole and discovers the Leprechaun's gold in an old tunnel where it was hidden by Father Jacob. Splitting up the gold (which is produced in a never ending amount by the chest it was contained in) evenly the quartet of friends use it to fulfill their fantasies, unaware that by taking the gold they have released the Leprechaun, who begins stalking the group (killing a guest who takes one of his coins at a party held by Jamie, prompting the police to temporarily arrest him). At the salon where Emily works the Leprechaun sneaks in and, after killing a regular customer, Doria, on the massage table by breaking her neck, attacks Emily, who barely escapes and warns Rory and the recently released Jamie, who rush to get to Lisa's. In her house Lisa is attacked by the Leprechaun and manages to fight him off for a short while, but is killed when the Leprechaun claws her in the stomach, with her friends finding her body moments later.While Emily and Jamie want to return the gold Rory does not and takes off with it; shortly after realizing Rory is gone Emily is attacked and chased outside by the Leprechaun, but is saved when Rory has a change of heart and comes back for her. Searching for Rory the Leprechaun stops by his house and kills Rory's profligate girlfriend Chanel (Keesha Sharp) by tearing out her upper jaw, reclaiming the gold she used to make a tooth while Rory and Emily are stopped and harassed by Officers Thompson (Beau Billingslea) and Whitaker (Chris Murray). After the Leprechaun appears and kills the two officers Emily and Rory escape and regroup with Jamie, only to be confronted by a machine gun wielding group of Rory's drug dealing rivals, led by Watson (Shiek Mahmud-Bey) and Cedric (Sticky Fingaz). Planning on executing Rory for infringing on their territory Watson and his gang are all disposed of by the Leprechaun, (who kills Watson and Cedric while the other two members run off) while Emily, Rory and Jamie drive off in Watson's car (which the Leprechaun latches to the bottom of for a short while) and go looking for help from Esmeralda.Advised to use four-leaf clovers against the Leprechaun by Esmeralda, Rory laces the hollow-point bullets of his gun with clovers Jamie finds in the marijuana Rory had earlier sold him. When the Leprechaun arrives Rory shoots him several times with the clover bullets, only for his gun to jam before he can finish the Leprechaun off. Rory and Emily are given the chance to run with the gold when the Leprechaun is distracted by Jamie and Esmeralda (the latter dying in a magical duel with the Leprechaun). Followed to the roof of the building Rory tries fighting the Leprechaun and is knocked out, though before the Leprechaun can kill him

Question: Context: In the opening scene, private detective Sam Grunion (Groucho Marx) explains to the viewers that he has been searching for the extremely valuable Royal Romanoff diamonds for eleven years, and his investigation leads him to a troupe of struggling performers, led by Mike Johnson (Paul Valentine), who are trying to put on a musical revue called 'Love Happy'.Grunion notes that the impoverished young dancers would starve were it not for the sweet, silent Harpo (Harpo Marx), at Herbert & Herbert, a gourmet food shop that also trafficks in stolen diamonds. Harpo kindly helps ladies with their shopping bags, all the while pilfering their groceries and stuffing them in the pockets of his long trench coat. When the elegant Madame Egelichi (Ilona Massey) arrives, store manager Lefty Throckmorton (Melville Cooper) tells her that "the sardines" have come in. Harpo sneaks into the basement and watches as Lefty lovingly unpacks a sardine can marked with a Maltese cross, and swipes the can from Lefty's pocket, replacing it with an unmarked one. Madame Egelichi, who has gone through eight husbands in three months in her quest for the Romanoff diamonds, is furious when Lefty produces the wrong can. When Lefty remembers seeing Harpo in the basement, she orders him to call the police and offer a $1,000 reward for his capture.At the theater, meanwhile, unemployed entertainer Faustino the Great (Chico Marx) asks Mike for a job as a mind-reader, and when Faustino's clever improvisation stops the show's backer, Mr. Lyons (Leon Belasco), from repossessing the scenery, Mike gratefully hires him. Harpo, who is secretly in love with dancer Maggie Phillips (Vera-Ellen), Mike's girl friend, gives her the sardine can, and she says she will eat them tomorrow. A policeman sees Harpo inside the theater and brings him to Madame Egelichi, who turns Harpo over to her henchmen, Alphonse (Raymond Burr) and Hannibal (Bruce Gordon) Zoto. After three days of interrogation, Harpo still refuses to talk, and when he is left alone, he calls Faustino at the theater, using the bike horn he carries in his pocket to communicate. Madame Egelichi listens on the extension as Faustino declares that there are plenty of sardines at the theater, and she goes there at once.Meanwhile, Mike has just finished telling the troupe that they do not have enough money to open when Madame Egelichi arrives and offers to finance the show. Mike cancels his plans to take Maggie out for her birthday so that he and his new backer can discuss the arrangements. In the alley outside the theater, Harpo, having escaped from Madame Egelichi's suite, finds the diamonds in the sardine can which had been set out for a cat, and puts them in his pocket. When he finds Maggie crying in her dressing room, Harpo takes her to Central Park, where he plays the harp for her and gives her the diamonds as a birthday gift.On the opening night of the show, Grunion is visited by an agent of the Romanoff family, who threatens to kill him if he does not produce the diamonds in an hour. At the theater, Lefty and the Zoto brothers spy through a window as Maggie puts on the diamond necklace, but Mike asks her not to wear it, promising to buy her an engagement ring instead. As they kiss, Maggie removes the necklace and drops it on the piano strings. The curtain goes up, and when Harpo sees Lefty and the Zoto brothers menacing Maggie, he distracts them with a piece of costume jewelry and leads them up to the roof.Meanwhile, on stage, Faustino plays the piano, and when he strikes the keys forcefully, the diamond necklace flies into the air, drawing the attention of Madame Egelichi, who is watching from the audience. Faustino pockets the diamonds, then rushes to the roof to help Harpo. Madame Egelichi shows up with a gun and demands the necklace, but Faustino gives her the fake diamonds. After tying up Lefty and the Zotos and recovering the real diamonds, Harpo encounters Grunion, who has been hiding on the roof. Harpo drops the diamonds in Grunion
