The following appeared as part of an article in a trade publication.
"Stronger laws are needed to protect new kinds of home-security systems from being copied and sold by imitators. With such protection, manufacturers will naturally invest in the development of new home-security products and production technologies. Without stronger laws, therefore, manufacturers will cut back on investment. From this will follow a corresponding decline not only in product quality and marketability, but also in production effeciency, and thus ultimately a loss of manufacturing jobs in the industry."

想了好几遍，还是没有凑够3个攻击点。请教各位啦
