现在的集成电路是靠连接线路元件的金属导线来传递信号。量子效应集成电路的基本概念是不用导线，四五个量子箱组成一个基本单元，靠单元之间的相互作用来传递信号。这种信号是封闭在量子箱里的电子之间相互产生的库仑作用而进行运动和变化的。量子效应集成电路的设计思想十多年前就已经提出，其目的是为了开发集成度更高，耗电更低的大规模集成电路。量子电路在理论上被认为是可行的，然而多年来其研究只停留在两个单元结合的实验上，而且很难实现稳定的信号传递。 这段文字支持的观点是( )。

A．量子效应集成电路是集成度更高、耗电更低的大规模集成电路

B．量子电路在理论上可行在实际中却不能实现

C．量子箱里传递的信号就是量子箱里电子之间的运动和变化

D．量子效应集成电路不能稳定地传递信号

(b) Jack and Jill are the directors of All-Bright Sdn Bhd, a company trading in lights and lighting equipment. In the last couple of years business has been bad and the company is hopelessly insolvent. Despite this situation, two months ago, Jack and Jill, in collaboration with Ben, the office manager, bought in the name of the company, RM1 million worth of lighting equipment on credit from Starlight Bhd, without disclosing the company’s financial position. It was clear that there was no intention on the part of Jack, Jill and Ben to pay Starlight Bhd for the lighting equipment.
