Question: Claude Rains and James Stewart in Mr. Smith Goes to Washington Play media Trailer James Stewart and Jean Arthur in a taxicab The governor of an unnamed western state, Hubert "Happy" Hopper (Guy Kibbee), has to pick a replacement for recently deceased U.S. Senator Sam Foley. His corrupt political boss, Jim Taylor (Edward Arnold), pressures Hopper to choose his handpicked stooge, while popular committees want a reformer, Henry Hill. The governor's children want him to select Jefferson Smith (James Stewart), the head of the Boy Rangers. Unable to make up his mind between Taylor's stooge and the reformer, Hopper decides to flip a coin. When it lands on edge and next to a newspaper story on one of Smith's accomplishments he chooses Smith, calculating that his wholesome image will please the people while his naivete will make him easy to manipulate. Junior Senator Smith is taken under the wing of the publicly esteemed, but secretly crooked, Senator Joseph Paine (Claude Rains), who was Smith's late father's friend. Smith develops an immediate attraction to the senator's daughter, Susan (Astrid Allwyn). At Senator Paine's home, Smith has a conversation with Susan, fidgeting and bumbling, entranced by the young socialite. Smith's naive and honest nature allows the unforgiving Washington press to take advantage of him, quickly tarnishing Smith's reputation with ridiculous front page pictures and headlines branding him a bumpkin. To keep Smith busy, Paine suggests he propose a bill. With the help of his secretary, Clarissa Saunders (Jean Arthur), who was the aide to Smith's predecessor and had been around Washington and politics for years, Smith comes up with a bill to authorize a federal government loan to buy some land in his home state for a national boys' camp, to be paid back by youngsters across America. Donations pour in immediately. However, the proposed campsite is already part of a dam-building graft scheme included in an appropriations bill framed by the Taylor political machine and supported by Senator Paine. Unwilling to crucify the worshipful Smith so that their graft plan will go through, Paine tells Taylor he wants out, but Taylor reminds him that Paine is in power primarily through Taylor's influence. Through Paine, the machine in his state accuses Smith of trying to profit from his bill by producing fraudulent evidence that Smith already owns the land in question. Smith is too shocked by Paine's betrayal to defend himself, and runs away. Saunders, who looked down on Smith at first, but has come to believe in him, talks him into launching a filibuster to postpone the appropriations bill and prove his innocence on the Senate floor just before the vote to expel him. In his last chance to prove his innocence, he talks non-stop for about 24 hours, reaffirming the American ideals of freedom and disclosing the true motives of the dam scheme. Yet none of the Senators are convinced. The constituents try to rally around him, but the entrenched opposition is too powerful, and all attempts are crushed. Owing to the influence of Taylor's machine, newspapers and radio stations in Smith's home state, on Taylor's orders, refuse to report what Smith has to say and even distort the facts against the senator. An effort by the Boy Rangers to spread the news in support of Smith results in vicious attacks on the children by Taylor's minions. Although all hope seems lost, the senators begin to pay attention as Smith approaches utter exhaustion. Paine has one last card up his sleeve: he brings in bins of letters and telegrams from Smith's home state, purportedly from average people demanding his expulsion. Nearly broken by the news, Smith finds a small ray of hope in a friendly smile from the President of the Senate (Harry Carey). Smith vows to press on until people believe him, but immediately collapses in a faint. Overcome with guilt, Paine leaves the Senate chamber and attempts to commit suicide, but is stopped by other senators. When he is stopped, he bursts back into the Senate chamber, loudly confessing to the whole scheme;

Answer: Who plays Hopper?

Question: Oil is a liquid fossil fuel that is extremely useful because it can be transported easily and can be used in cars and other vehicles. Oil is currently the single largest source of energy in the world. Oil from the ground is called crude oil, which is a mixture of many different hydrocarbons. Crude oil is a thick dark brown or black liquid hydrocarbon. Oil also forms from buried dead organisms, but these are tiny organisms that live on the sea surface and then sink to the seafloor when they die. The dead organisms are kept away from oxygen by layers of other dead creatures and sediments. As the layers pile up, heat and pressure increase. Over millions of years, the dead organisms turn into liquid oil. In order to be collected, the oil must be located between a porous rock layer and an impermeable layer (Figure 1.1). Trapped above the porous rock layer and beneath the impermeable layer, the oil will remain between these layers until it is extracted from the rock. Oil (red) is found in the porous rock layer (yellow) and trapped by the impermeable layer (brown). The folded structure has allowed the oil to pool so a well can be drilled into the reservoir. To separate the different types of hydrocarbons in crude oil for different uses, the crude oil must be refined in refineries like the one shown in Figure 1.2. Refining is possible because each hydrocarbon in crude oil boils at a different temperature. When the oil is boiled in the refinery, separate equipment collects the different compounds. Most of the compounds that come out of the refining process are fuels, such as gasoline, diesel, and heating oil. Because these fuels are rich sources of energy and can be easily transported, oil provides about 90% of the energy used for transportation around the world. The rest of the compounds from crude oil are used for waxes, plastics, fertilizers, and other products. Gasoline is in a convenient form for use in cars and other transportation vehicles. In a car engine, the burned gasoline mostly turns into carbon dioxide and water vapor. The fuel releases most of its energy as heat, which causes the gases to expand. This creates enough force to move the pistons inside the engine and to power the car. Refineries like this one separate crude oil into many useful fuels and other chemi- cals.

The United States has only about 1.5% of the worlds proven oil reserves, so most of the oil used by Americans must be imported from other nations. The main oil-producing regions in the United States are the Gulf of Mexico, Texas, Alaska, and California (Figure As in every type of mining, mining for oil has environmental consequences. Oil rigs are unsightly (Figure 1.4), and spills are too common (Figure 1.5). Click image to the left or use the URL below. URL: Offshore well locations in the Gulf of Mex- ico.

Question: Clinical evidence for failure with beta-lactam therapy has been lacking for patients with borderline oxacillin-resistant Staphylococcus aureus (BORSA) infections. We describe a failure of cloxacillin for a patient with endocarditis due to BORSA. The isolate also had false-negative thermonuclease and coagulase test results.

Answer:
