Article: I am in my father's house in Connecticut, sitting at a crowded table with my brother, my two sisiters and all our partners, talking about a tree. "He doesn't want it cut down." My sister says when my father has gone to bed and none of us speaks of the tree in his presence. "He says he usef to climb it when he was a boy." When I was last here, a year and a half ago, for my father's 90th birthday, Hurricane Irene drove seawater into the roads. The large tree that hangs over the houses swayed alarmingly, but it stayed up. Last October, Hurricane Sandy acused a great deal of damage. Six months on, many of the surrounding houses are on sale, but the tree that hangs over the house still stands. "That tree," my brother says, "has survived the two worst storms of the last 100 years." Though my brother thinks highly of the amazing staying power of the tree, my sister says that the tree should never have been planted: it stops light from reaching the house. My other sister's partner says that all trees fall down eventually. There is plenty of evidence for what he says: throughout the neighborhood, the ramains of similarly sized trees lie on their sides, with their roots in the air. During this discussion, I offer to pay a quarter of whatever is required to remove the tree. "A guy I talked to," my brother says, "told me it could cost us$10,000." As night wears on, the discussion becomes increaslingly meaningless. There is no point in reaching any kind of agreement, since the decision is not for us to make. It's my father's tree, and he has refused to cut down the only thing in the neighborhood older than him.
Question: When does the discussion take place?
Options: (A) After lunch (B) After supper (C) At the weekend (D) Before their father's 90th birthday
B

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.

Article: Burns can be caused by fire, the sun, chemicals, heated objects or fluids, and electricity. They can be minor problems or life-threatening emergencies. Distinguishing a minor burn from a more serious burn involves determining the degree of damage to the tissues of the body. If you are not sure how serious the burn is, seek emergency medical help. First-degree burns are those in which only the outer layer of skin is burned. The skin is usually red and some swelling and pain may occur. Unless the burn involves large portions of the body, it can be treated at home. Second-degree burns are those in which the first layer of skin has been burned through and the second layer of skin is also burned. In these burns, the skin reddens intensely and blisters develop. Severe pain and swelling also occur. Second-degree burns require medical treatment. Third-degree burns are the most serious and involve all layers of skin. Fat, nerves, muscles, and even bones may be affected. Areas may be charred black or appear a dry white. If nerve damage is substantial, there may be no pain at all. These burns require emergency medical attention. Follow these steps when treating minor burns at home 1) If the skin is not broken, run cool water over the burn for several minutes. 2) Cover the burn with a sterile bandage or clean cloth. 3) Take aspirin to relieve any swelling or pain. Seek emergency treatment immediately for major burns. Before an emergency unit arrives, follow these steps 1) Remove the person from the source of the burn (fire, electrical current, etc.). 2) If the person is not breathing, begin mouth-to-mouth resuscitation immediately. 3) Remove all clothing to stop further burning. If the clothing is stuck to the burn, do not attempt to remove it. 4) Cover the burned area with a cool, moist, sterile bandage or clean cloth. Do not place any creams, ointments or ice on the burned area or break blisters. 5) Monitor the patient for signs of shock, and treat accordingly.

Options: (A) what kind of treatment they need (B) what kind of tissue of the body is damaged (C) whether there is pain and what degree of pain there is (D) which layer of skin is burned
