Events【C4】______ the plant and animal affect its actions.

The fur becomes gray-brown in longer【C7】______ of daylight in summer.
【C8】______signals control other biological clocks. German scientists found that some internal one seems to order birds to begin their【C9】______ flights two times each year. Birds prevented from flying become【C10】______ when it is time for the trip.【C11】______ they become calm again when the time of the flight has ended. A mix of outside and internal events controls some biological clocks; such things as heartbeat and the daily change from sleep to walking take place because of both external and internal signals.
Scientists are beginning to learn【C12】______ parts of the brain contain the biological clocks. A researcher at Harvard University, Dr. Martin Moore Ede, said a small group of cells near the front of the brain seemed to control the【C13】______ of some of our actions. Probably there are other cells to control other body activities. He is studying【C14】______ they affect the way we do our work. Most of us have great difficulty if we【C15】______ often change to different work hours.【C16】______ can take many days for a human body to【C17】______ a major change in work hours.

Research on the question is sparse and contradictory. Research in the area has pointed to two competing hypotheses, according to Nancy Marshall, participant of Wellesley College's Center for Research on Women. One, the "scarcity hypothesis", presumes people have a limited amount of time and energy and that women with competing demands suffer from overload and inter-role conflict. The other, the "enhancement hypothesis", theorizes that the greater self-esteem and social support people gain from multiple roles outweigh the costs. Marshall's own research supports both notions.
Citing results from two studies she recently conducted, she explained that having children gives working women a mental and emotional boost that childless women lack. But having children also increases work and family strain, indirectly increasing depressive symptoms, she found.
The reason multiple roles can be both positive and negative has to do with traditional gender roles, agreed the experts. Despite women's movement into the paid labor force, they still have primary responsibility for the "second shift" — household work and childcare. The debate about women's multiple roles could be rendered obsolete by changes in societal expectations, many experts in the field believe.
"Individual decisions about work and family take place in a social and cultural context," said Gunn Johansson, PhD, professor of work psychology at the University of Stockholm. "Society sends encouraging or discouraging signals about an individual's choices and about the feasibility of combining work and family."
According to Johansson, these signals come not only in the form. of equal employment opportunity laws, but also in the support society makes available to families. A researcher in her department, for instance, compared the plight of women managers in Sweden and the former West Germany. Although the two societies are quite similar, they differ in one important respect: Sweden offers high-quality child care to almost every family that requests it.
Preliminary results from the study are striking. In Sweden, most of the women managers had at least two children and sometimes more; in Germany, most were single women with no children. "These women were reading the signals from their society," Johansson said. While the German women recognized that they had to forsake family for work, the Swedish women took it as their right to combine the two roles.
The argument of this article is centered around ______.
A．the multiple roles a woman should have in society
B．the two opposing hypothesises about working women
C．the way working women win their self-esteem and social support
D．the overload and inter-role conflict a working woman has to face

听力原文：M: So how come you chose psychology？
W: Well, at lust I didn't have any clear idea of what I wanted to do after university, I didn't say to myself "I want to be a clinical psychologist or a researcher or anything like that". I suppose I have just always been interested in people and the way they act.
M: And what was the course like？
W: It was just great. The teachers were all really friendly and they had this special approach to teaching. The whole course was based on a problem-solving approach.
M: I see from your CV that you graduated in 1997 and after that, let me see...
W: I got a job with the department of employment. It was only a temporary thing for about six months. I used to have to design questionnaires and things like that for surveys that they carried out. And I guess the psychology course at college helped me a lot.
M: So why did you leave？
W: Well, four years is a long time to be asking people questions. You know those sorts of questions about washing powder and shampoo. After two years of doing that I felt that while I could do it well, now I want to do something else that's a little different. It just wasn't challenging for me any more and because I needed a challenge I decided to move when I heard about the position of Senior Researcher here at institute I knew that's exactly what I want.
