单选题A wheel is any dish like object that can be used for transportation or in machinery. To be useful, a wheel must revolve (1) an axle, which is normally a shaft attached (2) the wheel's center.

单选题The following two questions refer to the following passage: A prestigious private high school has made available to local families a tuition prepayment plan to ease the burden of paying the school's hefty tuition when a student matriculates. The plan allows parents of children under three years old to reserve a spot for their child at the school by making a payment of one-fourth of the current annual tuition for the high school. The parents then make an identical payment every year for the next 15 years, and the student's full four-year tuition is considered paid in full, regardless of how much the regular tuition payments have risen in the intervening years.

单选题 Researchers have found that REM (rapid eye movement) sleep is important to human beings. This type of sleep generally occurs four or five times during one night of sleep lasting five minutes to forty minutes for each occurrence. The deeper a person's sleep becomes, the longer the periods of rapid eye movement. There are physical charges in the body to show that a person has changed from NREM (non-rapid eye movement) to REM sleep. Breathing becomes faster, the heart rate increases, and, as the name implies, the eyes begin to move quickly. Accompanying these physical changes in the body is a very important characteristic of REM sleep. It is during REM sleep that a person dreams.

单选题{{B}}Passage Three{{/B}} Despite efforts to provide them with alternatives such as the shelter, women frequently and repeatedly returned to violent and abusive partners. By the late 1970s, feminists at Women Together, like those doing similar work throughout the United States, began to understand that battered women experience a range of post-traumatic psychological responses to abuse, similar to those of victims of other types of violence or trauma. Subsequently, the psychological response of battered women became reified as "battered woman syndrome," a sub-category of post-traumatic stress disorder. Interestingly, in the course of trying to create social change, the focus of feminists perceptibly shifted to trying to explain why battered women fail to leave the partners who beat them. In trying to address this question, a debate ensued among feminists and mental health workers as to potential merits and problems of categorizing as mental disorder what many feminists labeled a normal response to fear and an appropriately angry response to abuse. Although many women left abusive relationships or successfully ended violence by other means, some responded to ongoing or accelerated abuse by killing or trying to kill their male partners. In many states, when they went to trial, such women found they were restricted from introducing testimony about the abuse they had endured or their resulting states of mind. In trying to address these women's needs, some activists and scholars advocated the use of expert testimony to explain battered woman syndrome to juries. This strategy would introduce evidence of past abuse and challenge the gender biases of self-defense law by explaining the woman's state of mind at the time of the offense. Feminist legal scholars raised potential problems in the use of battered woman syndrome. They argued that it could be used against women who did not neatly fit pre-established criteria and had the potential to become another example of the tendency to label women's normal angry responses as mental illness. While the desirability of working to admit expert testimony was debated, individual state courts and legislatures varied in their willingness to recognize battered woman syndrome, permit evidence of past abuse, or allow expert testimony. As the legal debate about battered women's responses to violence was beginning to unfold, the Ohio movement became directly involved in it when a former shelter resident, shot and killed her abusive common law husband. In 1978 Women Together, in conjunction with the woman's lawyer, decided to challenge existing law by trying to introduce battered woman syndrome expert testimony at trial. Because at the time the syndrome had little scientific merit or legal recognition, the trial court declared inadmissibility, a decision upheld by the State Supreme Court (State v. Thomas 1981 66 Ohio St. 2d 51). Women Together founders left the shelter to establish professional careers, viewing this as a means of advancing the feminist agenda. The frustrations, limitations and defeats they had experienced as outside challengers impelled them to adopt a strategy of infiltration and appropriation of the institutions they sought to change. For example, one founder, who had worked through lobbying for ERA America in addition to her other feminist activism, explained her decision to run for elected office by saying: "[When ERA was defeated] I decided to run for the legislature. I said 'I can do better than these turkeys. '"
