In this task, you're given an article, a question which often contains a blank and four options (associated with "A", "B", "C", "D"). Your task is to find the correct answer (from the given options) for the question from the given article and return one of the options from "A", "B", "C", and "D". Do not generate anything else apart from one of the following characters: "A", "B", "C", "D". There is only one correct answer for each question.

Example Input: Article: A scientist working at her lab bench and a six-old baby playing with his food might seem to have little in common.After all,the scientist is engaged in serious research to uncover the very nature of the physical world,and the baby is,well, just playing...right?Perhaps,but some developmental psychologists have argued that this"play"is more like a scientific investigation than one might think. Take a closer look at the baby playing at the table.Each time the bowl of rice is pushed over the table edge,it falls in the ground---and, in the process, it belongs out important evidence about how physical objects interact ; bowls of rice do not flood in mid-sit, but require support to remain stable. It is likely that babies are not born knowing the basic fact of the universe; nor are they ever clearly taught it. Instead, babies may form an understanding of object support through repeated experiments and then build on this knowledge to learn even more about how objects interact. Though their ranges and tools differ, the baby's investigation and the scientist's experiment appear to share the same aim(to learn about the natural world ), overall approach (gathering direct evidence from the world), and logic (are my observations what I expected?). Some psychologists suggest that young children learn about more than just the physical world in this way---that they investigate human psychology and the rules of language using similar means. For example, it may only be through repeated experiments, evidence gathering, and finally overturning a theory, that a baby will come to accept the idea that other people can have different views and desires from what he or she has, for example, unlike the child , Mommy actually doesn't like Dove chocolate. Viewing childhood development as a scientific investigation throws on how children learn ,but it also offers an inspiring look at science and scientists. Why do young children and scientists seem to be so much alike? Psychologists have suggested that science as an effort ---the desire to explore, explain, and understand our world---is simply something that comes from our babyhood. Perhaps evolution provided human babies with curiosity and a natural drive to explain their worlds, and adult scientists simply make use of the same drive that served them as children. The same cognitive systems that make young children feel good about feel good about figuring something out may have been adopted by adult scientists. As some psychologists put it, "It is not that children are little scientists but that scientists are big children."

Example Input: Article: New research at Washington University School of Medicine in St. Louis shows that people who struggle with mood problems or addiction can safely quit smoking and that kicking the habit is associated with improved mental health. Cavazos-Rehg, an assistant professor of psychiatry, found that quitting or significantly cutting back on cigarette smoking was linked to improved mental health outcomes. Quitting altogether or reducing by half the number of cigarettes smoked daily was associated with lower risk for mood disorders like depression, as well as a lower likelihood of alcohol and drug problems. "We don't know if their mental health improves first and then they are more motivated to quit smoking or if quitting smoking leads to an improvement in mental health," Cavazos-Rehg said. "But either way, our findings show a strong link between quitting and a better psychiatric outlook." In addition, she believes the serious health risks associated with smoking make it important for doctors to work with their patients to quit, regardless of other psychiatric problems. "About half of all smokers die from related to smoking, so we need to remember that as complicated as it can be to treat mental health issues, smoking cigarettes also causes very serious illnesses that can lead to death," she explained. Cavazos-Rehg and her team analyzed questionnaires gathered as part of the National Epidemiologic Study on Alcohol and Related Conditions. In the early 2000s, just under 35,000 people were surveyed. As part of the study, they answered questions about drinking, smoking and mental health in two interviews conducted three years apart. The researchers focused on data from 4,800 daily smokers. Those who had addiction or other psychiatric problems at the time of the first survey were less likely to have those same problems three years later if they had quit smoking. And those who hadn't had psychiatric problems at the initial survey were less likely to develop those problems later if they already had quit. "We really need to spread the word and encourage doctors and patients to tackle these problems," Cavazos-Rehg said. "When a patient is ready to focus on other mental health issues, it may be an ideal time to address smoking cessation, too."
Question: What is the main idea of the passage?
Options: (A) Smoking was associated with alcohol and drug problems. (B) Quitting smoking may help to improve mental health. (C) Smoking can lead to cancer or other deadly problems. (D) Those who had mental problem are more motivated to quit smoking.
Example Output: B
