Input: Consider Input: Article: Mark Twain left school when he was twelve. He had little school education. In spite of this, he became the most famous writer of his time. He made millions of dollars by writing. His real name was Samuel Langhorne Clemens, but he is better known to all over the world as Mark Twain, his penname. Mark Twain was born in 1835 and he was not a healthy baby. In fact, he was not expected to live through the first winter. But with his mother's care, he managed to survive. As a boy, he caused much trouble for his parents. He used to play jokes on all his friends and neighbors. He didn't like to go to school, and he often ran away from home. He always went in the direction of the nearby Mississippi. He was nearly drowned nine times. After his father's death, Mark Twain began to work for a printer, who only provided him with food and clothing. Then, he worked as a printer, a river-boat pilot and later joined the army. But shortly after that he became a miner. During this period, he started to write short stories. Afterwards, he became a full-time writer. In 1870, Mark Twain got married. In the years that followed he wrote many books including The Adventures of Tom Sawyer in 1876, and The Adventures of Huckleberry Finn in 1884, which made him famous, and brought him great fortune. Unfortunately, Mark Twain got into debts in bad investments and he had to write large numbers of stories to pay these debts. In 1904, his wife died, and then three of his children passed away. At the age of 70, his hair was completely white. He bought many white suits and neckties. He wore nothing but white from head to foot until his death on April 21, 1910.

Input: Consider Input: Article: For years, there has been a bias against science among clinical psychologists . In a two-year analysis to be published in November inPerspectives on Psychological Science, psychologists led by Timothy B. Baker of the University of Wisconsin charge that many clinical psychologists fail to "provide the treatments for which there is the strongest evidence of effectiveness" and "give more weight to their personal experiences than to science." As a result, patients have no guarantee that their "treatment will be informed by ... science." Walter Mischel of Columbia University is even crueler in his judgment. "The disconnect between what clinical psychologists do and what science has discovered is an extreme embarrassment," he told me, and "there is a widening gap between clinical practice and science." The "widening" reflects the great progress that psychological research has made in identifying the most effective treatments. Thanks to strict clinical trials, we now know that teaching patients to think about their thoughts in new, healthier ways and to act on those new ways of thinking are effective against depression, panic disorder and other problems, with multiple trials showing that these treatments -- the tools of psychology -- bring more lasting benefits than drugs. You wouldn't know this if you sought help from a typical clinical psychologist. Although many treatments are effective, relatively few psychologists learn or practice them. Why in the world not? For one thing, says Baker, clinical psychologists are "very doubtful about the role of science" and "lack solid science training". Also, one third of patients get better no matter what treatment (if any) they have, "and psychologists remember these successes, believing, wrongly, that they are the result of the treatment." When faced with evidence that treatments they offer are not supported by science, clinical psychologists argue that they know better than some study what works. A 2008 study of 591 psychologists in private practice found that they rely more on their own and colleagues' experience than on science when deciding how to treat a patient. If they keep on this path as insurance companies demand evidence-based medicine, warns Mischel, psychology will "discredit itself."

Options: (A) they are unfamiliar with their patients (B) they believe in science and evidence (C) they depend on their colleagues' help (D) they rely on their personal experiences
Asnwer: C

Output: No
