某药材公司与某制药厂签订的枸杞买卖合同约定:药材公司于当年9月底前将50吨枸杞交给制药厂,每吨1.2万元,制药厂在合同签订后5日内支付定金10万元,收货后20日内付清货款。合同还约定,药材公司迟交货1天,支付违约金500元;一方有其他违约情况,应向对方支付违约金1万元。因药材公司董事长出国,合同仅有药材公司的公章,董事长未签字。合同订立后,制药厂如期支付定金10万元。因枸杞产地连续下雨,加上药材公司组织收购不力,直至10月6日,药材公司才通过铁路运输将50吨枸杞发给制药厂。火车行进途中,遇山洪暴发,一部分货物被冲走。10月20日,制药厂收到货物,请当地卫生部门对该批货物进行检验,确认该批枸杞已不适宜做药材使用,故暂时存放在仓库里,并电告药材公司要求退货,双倍返还定金,支付违约金1万元。

At the beginning of the twentieth century, North American society held, as an ideal, the Nuclear Family. This presumably perfect residential, social, and economic unit consisted of an adult male, an adult female and their minor children. This structure was thought to be stable and long lasting.
However, a few decades later, the structure of that ideal family was being altered radically even while it was being touted as the structure to be aimed for. Popular magazines bemoaned the loss of the Nuclear Family and its replacement with inferior forms.
There are a number of factors that are acting in concert to apply pressure on the Nuclear Family and generate a variety of new structures. Some of these are:
The definition of marriage has changed somewhat in that few people now consider it to last "until death do us part". The concept of monogamy (the marriage of one man and one woman) has been modified to a form now referred to as serial monogamy (the marriage of one man and one woman at a time). This reflects the increasing equality of women and men in terms of economic advantage and the recognition that many women no longer depend on men for their survival. Women are acquiring independence and have become empowered to make their own choices. With this independence, the need to form a relationship with a man becomes less important. This change embodies the concept that the marriage is temporary and can be terminated by either partner at any time. Associated with this, of course, is the relaxation of the divorce laws and the significant reduction of the shame that had one time been attached to divorce.
The economy of North America has resulted in a two-tier system of a few rich who control most of the resources and a large portion of the population who control almost none of the resources. Because of this, many couples are forced to have both partners with full-time jobs outside the home. There are unintended byproducts of the need for a double income. The most important of these is the replacement of a mother-oriented socialization of children to a "stranger-oriented" socialization system reflected in the growth of the childcare industry. Also, either partner is financially able to end the marriage without significant hardship.
The combination of these changes will in the coming decades have a profound effect on the structure of the family of North America. As a result, the family will be a fluid, constantly changing structure with variable household arrangements as the norm.

What is the major factor that has raised the divorce rate in North America

A.The increasing equality of women.

B.Relaxation of the divorce laws.

C.The significant reduction of the shame on divorce.

D.Men having more chances to know women.
