According to sociologists, there are several different ways in which a person may become recognized as the leader of a social group in the United States. In the fanfily traditional cultural patterns confer (~z~,) leadership on one or both of the parents. In other cases, such as friendship groups, one or more persons may gradually emerge as leaders, although there is no formal process of selection. In larger groups, leaders are usually chosen formally through election or recruitment. Although leaders are often thought to be people with unusual personal ability, decades of research have failed to produce consistent evidence that there is any category of "natural leaders." It seems that there is no set of personal qualities that all leaders have in common; rather, virtually any person may be recognized as a leader if the person has qualities that meet the needs of that particular group. Furthermore, although it is commonly supposed that social groups have a single leader, research suggests that there are typically two different leadership roles that are held by different individuals. Instrumental leadership is leadership that emphasizes the completion of tasks by a social group. Group members look to instrumental leaders to "get things done." Expressive leadership, on the other hand, is leadership that emphasizes the collective well-beings of a social group's members. Expressive leaders are less concerned with the overall goals of the group than with providing emotional support to group members and attempting to minimize tension and conflict among them. Group members expect expressive leaders to maintain stable relationships within the group and provide support to individual members. Instrumental leaders are likely to have a rather  _ to other group members. They give orders and may discipline group members who prohibit attainment   of the group's goals. Expressive leaders cultivate a more personal or primary relationship to others in the group. They offer sympathy when someone experiences difficulties or... The passage indicates that instrumental leaders generally focus on A) ensuring harmonious relationships B) sharing responsibility with group members C) achieving a goal D) identifying new leaders

MEGADIM, Israel (AP)-The worst forest fire in Israel's history on Thursday destroyed one of the country's few forested areas, killing at least 36 guards on their way to rescue prisoners there, destroying homes and forcing the evacuation   of thousands. The fire ran through the Carmel forest in Israel's Galilee, reaching the coastal city of Haifa, jumping from place to place in the forest. The fire broke out around midday and quickly spread and was still burning out of control as midnight approached. Investigators   supposed that the fire could have been set accidentally, or it might have been a criminal act, but pretty much ruled out   some sort of attack by a Palestinian group. "This is a huge disaster," Prime Minister Benjamin Netanyahu said. "The government is using all means to control the fire." He said some countries such as Cyprus, Italy, Russia and Greece agreed to provide backup. Most of the dead were Prison Service guards racing through the fire toward a prison to evacuate the prisoners, most of them Palestinians. A tree fell across the road, blocking their bus. Some guards were burned alive inside, while others died as they tried to escape. Fourteen bodies were found near the burnt bus 10 hours after the fire started. The fire heavily damaged one of Israel's few large forests, made up of natural growth and planted areas, a favorite place for camping and a home for dozens of species of wildlife. Forestry workers tried to evacuate animals from the fire. The forest recovered slowly from a fire in 1989, but experts said Thursday's big fire was many times worse. The text is mainly about   _  . A) the worst forest fire in Israel's history B) the actual cause of the worst ever forest fire C) the damage caused by the forest fire D) the government's efforts in controlling the fire

Biologists believe that love is fundamentally a biological rather than a cultural construct, because the capacity for love is found in all human cultures and similar behavior is found in some other animals. In humans the purpose of all the desire is to focus attention on the raising of offspring. Children demand an unusual amount of parenting, and two parents are better than one. Love is a signal that both partners are committed, and makes it more likely that this commitment will continue as long as necessary for children to reach independence. But what does science have to say about the notion of love at first sight? In recent years the ability to watch the brain in action has offered a wealth of insight into the mechanics of love. Researchers have shown that when a person falls in love, a dozen different part of brain work together to release chemicals that trigger feelings of euphoria, bonding and excitement. It has also been shown that the unconditional love between a mother and a child is associated with activity in different regions of the brain from those associated with pair-bonding love. Passionate love is rooted in the reward circuitry of the brain--the same area that is active when humans feel a rush from cocaine. In fact, the desire, motivations and withdrawals involved in love have a great deal in common with addiction. Its most intense forms tend to be associated with the early stages of a relationship, which then give way to a calmer attachment form of love one feels with a long term partner. What all this means is that one special person can become chemically rewarding to the brain of another. Love at first sight, then, is only possible if the mechanism for generating long-term attachment can be triggered quickly. There are signs that it can be. One line of evidence is that people are able to decide within a second how attractive they find another person. This decision appears to be related to facial attractiveness, although men may favor women with waist-to-hip ratio of 0.7, no matter what... When a person falls in love,   _  . A) he feels as if he were addicted to cocaine B) he will be committed to the beloved as long as necessary C) he will experience a calmer attachment form of love before he feels the extreme love D) he will experience complex feelings brought on by different regions of his brain
