A major reason for conflict in the animal world is territory. The male animal (21) an area. The size of the area is sufficient to provide food for him, his (22) and their offspring. Migrating birds, for example, (23) up the best territory in the order of "first come, first (24) ." The late arrivals may acquire (25) territories, but less food is available, or they are too close to the (26) of the enemies of the species. (27) there is really insufficient food or the danger is very great, the animal will not (28) . In this way, the members of the species which are less fit will not have offspring.When there is conflict (29) . territory, animals will commonly use force, or a (30) of force, to decide which will stay and which will go. It is interesting to note, however, that animals seem to use (31) the minimum amount of force (32) to drive away the intruder. There is usually no killing. In the (33) of those animals which are capable of doing each other great harm, (34) is a system for the losing animal to show the winning animals that he (35) to submit. When he shows this, the (36) normally stops fighting. Animals (especially birds), which can easily escape from conflict seem to have (37) obstacle against killing, and equally no mechanism (38) submission. The losing bird simply flies away. However, if two doves are (39) in a cage, and they start fighting, they will continue to fight until one kills the other. We all think of the dove as a symbol of peace and, in its natural habitat, it is peaceful. But the "peace" mechanism does not (40) in a cage. 37()

The key position and role of women in the process of development is increasingly being recognized. Although the three great World Conferences of Women were more concerned with recognizing and compiling approaches to emancipation we can currently confirm a general sharpening of awareness. It has become clear that the Third World cultures, in earlier times strongly matriarchal, have been weakened in this respect by the methods of colonial education which are almost exclusively directed towards the male. Of the many criticisms of this situation let one voice be heard: "Development education’ groups and programs are very much male dominated and lack woman’s perspective". So, too, the hopes placed in vocational training--"vocationalization’--as an aid to equality have been disappointed since this in its turn was to large extent focused on the male.In these circumstances we should not be surprised that until now women have participated least in the educational processes which have been introduced. Only 20% attend primary school and the percentage of those who leave early is highest among girls. Because of the lack of basic training only around 10% take part in Adult Education programs. Hence it is vitally important to secure a turning point by increasing the awareness of the need for education.The International Conference at Jomtien in 1990 provided the solution to this: "A more educated mother raises a healthier family. She has fewer and better educated children. She is more productive at home and in the workplace and is better able to get further education." Many problems in school are consequences of incorrect or improperly balanced nutrition combined with .inadequate hygiene. Together these factors can lead to failure to keep pace in school.Hence even primary education for girls should be directed towards the basic needs and necessities and provide answers which are as simple as possible. In rural districts such answers will be different from those given in urban areas. The education of girls and women must to a large degree be an education for the life they will lead, tailored to a woman’s position. In saying this we are in fact demanding that the education of women, like all educational work in the Third World, should be an integrated part of the community. Consequently there are many partners in this process school, family, small businesses, governmental and non-governmental organizations. The educational skill consists in keeping this interplay active in such a way that there is no deficiency in material content. An important consequence of this is the awakening of the desire to question, which, on the one hand presses for further education and on the other hand for its practical application. The author argues in the passage that ()
A. the education of women should be a process of community activity
B. the education of women should be a part of community in which many partners are combined
C. women should like all educational work in the Third World
D. the education of women should be organizations run by government
The Supreme Court’s decisions on physician-assisted suicide carry important implications for how medicine seeks to relieve dying patients of pain and suffering.Although it ruled that there is no constitutional right to physician-assisted suicide, the Court in effect supported the medical principle of "double effect," a centuries-old moral principle holding that an action having two effects--a good one that is intended and a harmful one that is foreseen--is permissible if the actor intends only the good effect.Doctors have used that principle in recent years to justify using high doses of morphine to control terminally ill patients’ pain, even though increasing dosages will eventually kill the patient.Nancy Dubler, director of Montefiore Medical Center, contends that the principle will shield doctors who "until now have very, very strongly insisted that they could not give patients sufficient medication to control their pain if that might hasten death."George Annas, chair of the health law department at Boston University, maintains that, as long as a doctor prescribes a drug for a legitimate medical purpose, the doctor has done nothing illegal even if the patient uses the drug to hasten death. "It’s like surgery," he says. "We don’t call those deaths homicides because the doctors didn’t intend to kill their patients, although they risked their death. If you’re a physician, you can risk your patient’s suicide as long as you don’t intend their suicide."On another level, many in the medical community acknowledge that the assisted-suicide debate has been fueled in part by the despair of patients for whom modern medicine has prolonged the physical agony of dying.Just three weeks before the Court’s ruling on physician-assisted suicide, the National Academy of Science (NAS) released a two-volume report, Approaching Death: Improving Care at the End of Life. It identifies the undertreatment of pain and the aggressive use of "ineffectual and forced medical procedures that may prolong and even dishonor the period of dying" as the twin problems of end-of-life care.The profession is taking steps to require young doctors to train in hospices, to test knowledge of aggressive pain management therapies, to develop a Medicare billing code for hospital-based care, and to develop new standards for assessing and treating pain at the end of life.Annas says lawyers can play a key role in insisting that these well-meaning medical initiatives translate into better care. "Large numbers of physicians seem unconcerned with the pain their patients are needlessly and predictably suffering," to the extent that it constitutes "systematic patient abuse." He says medical licensing boards "must make it clear...that painful deaths are presumptively ones that are incompetently managed and should result in license suspension. Which of the following best defines the word "aggressive" (Paragraph 7)()
A. Bold
B. Harmful
Careless
Desperate
