Q: Delamanid (OPC-67683), a nitro-dihydro-imidazooxazole derivative, is a new antituberculosis medication that inhibits mycolic acid synthesis and has shown potent in vitro and in vivo activity against drug-resistant strains of Mycobacterium tuberculosis. In this randomized, placebo-controlled, multinational clinical trial, we assigned 481 patients (nearly all of whom were negative for the human immunodeficiency virus) with pulmonary multidrug-resistant tuberculosis to receive delamanid, at a dose of 100 mg twice daily (161 patients) or 200 mg twice daily (160 patients), or placebo (160 patients) for 2 months in combination with a background drug regimen developed according to World Health Organization guidelines. Sputum cultures were assessed weekly with the use of both liquid broth and solid medium; sputum-culture conversion was defined as a series of five or more consecutive cultures that were negative for growth of M. tuberculosis. The primary efficacy end point was the proportion of patients with sputum-culture conversion in liquid broth medium at 2 months. Among patients who received a background drug regimen plus 100 mg of delamanid twice daily, 45.4% had sputum-culture conversion in liquid broth at 2 months, as compared with 29.6% of patients who received a background drug regimen plus placebo (P=0.008). Likewise, as compared with the placebo group, the group that received the background drug regimen plus 200 mg of delamanid twice daily had a higher proportion of patients with sputum-culture conversion (41.9%, P=0.04). The findings were similar with assessment of sputum-culture conversion in solid medium. Most adverse events were mild to moderate in severity and were evenly distributed across groups. Although no clinical events due to QT prolongation on electrocardiography were observed, QT prolongation was reported significantly more frequently in the groups that received delamanid. Delamanid was associated with an increase in sputum-culture conversion at 2 months among patients with multidrug-resistant tuberculosis. This finding suggests that delamanid could enhance treatment options for multidrug-resistant tuberculosis.

Q: One day, a slave owner entered a local store and threatened a young boy who was his slave. At first, the slave refused to move and ran for the door. The slave owner reached for a heavy weight. He threw it at his slave. Instead, it hit Harriet on the head. Harriet almost died. For the rest of her life, she carried the mark of a deep wound on her head. Miser Brodas felt he never needed Harriet. He decided to sell her. Harriet thought of a way to prevent this. Each time she was shown to someone who might buy her, she acted as if she were falling asleep. After a while, Mister Brodas gave up the hope of selling Harriet. He sent her back to the fields. At 24 she married a free black man, John Tubman. By then, Harriet was sure she should escape. In 1849, Mister Brodas died. His slaves probably would be sold to further South. John Tubman tried to make Harriet forget about running away. Harriet decided she must end her marriage and that she needed to tell her family that she was leaving. Harriet escaped for Pennsylvania where slavery was banned there. Once she hid under hay that had been cut from the fields. Another time, she wore men's clothing. Finally, she arrived in Pennsylvania. Now that Harriet was free, she didn't forget other slaves in Maryland. During the next ten years, she freed her parents and other family members. She traveled back and forth eighteen times, helping about 300 slaves escape. She became an expert at hiding from slave hunters. At one time, anyone finding Harriet was promised 40,000dollars for catching her--dead or alive. The people she helped called her Moses. She had rescued them from slavery just as the biblical Moses rescued the Jews. After the Civil War began, Harriet started to spy for the North. She also served as a nurse. After four years of bloody fighting, the North won the war. Abraham Lincoln freed the slaves in 1863. There was no longer any need for Harriet to be Moses.

A: We know from the passage that Harriet was Mister Brodas'    .

Q: The scene opens with Ellen (Sharon Stone) riding across the prairie toward a town, when an idiot digging multiple holes looking for his gold, shoots at her. She falls off her horse and knocks him out as he checks to see if she is dead. After chaining him to his wagon, she continues into town. A large, single elimination gun fighting tournament is about to begin and she is looking for revenge on the man ( Herod/Gene Hackman) who killed her father. She arrives at the bar/hotel. Ace Hanlon shows off his deck of cards with an ace for every man he has killed. Soon, the saloon comes to life as Scars who just got out of jail, comes back to settle a score. He makes a move on Ellen, and she tells him to take a bath. Scars gets angry and kicks the blind boy's peddling wagon, as he was talking to Ellen. Later at the drafting of the tournament, the saloon owner is to sign up 16 gunfighters. Among them are The Kid (Leonardo DiCaprio), Sgt. Cantrell (Kieth David), Cort, the marksman and odds on favorite (Russell Crowe) though he was signed up against his will. Cort was an outlaw who became a preacher and built a mission. Since he was one of Herod's partners in crime, Herod now wants Cort dead. Also in the contest is Ace Hanlon ( Lance Herrickson), A Swedish Champ. and of course Herod. Anyone can challenge anyone, and each fighter must accept the first challenge. Ellen is challenged by the idiot who was digging for his lost gold. But up first was the Kid and he quickly shot the Swede and the winner is the last standing.The Swede was shot twice and then threw his gun down. Also winning, were Stg.
