题干阅读理解：根据文章内容，选择正确答案（每题10分）。 China has the most franchises in the world but the scale of their operations is relatively small. Each system in China has an average of 43 outlets, compared to more than 540 in the United States. Together, there are 2,600 brands in some 200,000 retail markets. KFC was the most significant foreign entry in 1987 and is widespread. Many franchises are in fact joint-ventures, as at their forming the franchise law was not explicit. For example, McDonald's is a joint venture. Pizza Hut, TGIF, Wal-mart, Starbucks followed a little later. But total franchising is only 3% of retail trade, which seeks foreign franchise growth. The year 2005 saw the birth of an updated franchise law, “Measures for the Administration of Commercial Franchise”. Previous legislation (1997) made no specific inclusion of foreign investors. Today the franchise law is much clearer by virtue of the 2007 law, a revision of the 2005 law. The laws are applicable if there are transactions involving a trademark combined with payments with many obligations on the franchisor. The law comprises 42 articles and eight chapters. 1.
