Q: Article: Australian scientists say an organic compound used by Indian women to paint dots or bindi on their foreheads could hold the key to a breakthrough in cancer treatment. Rose Bengal was first used in the early 1900s as a dye for food, textiles and cosmetics. But now it is proving to be a useful weapon in the fight against skin cancer. Television advertisements constantly warn of the dangers of overexposure to the fierce sun. Among them is the possibility of the disease melanoma , a type of skin cancer. More than 1,200 Australians die every year from the disease. Initial trials of a solution of Rose Bengal injected into some melanoma cells have had a 75 percent success rate in controlling the disease. Professor John Thompson, the director of the Melanoma Unit at the University of Sydney, says this organic dye could become a powerful cancer-fighting treatment. "We believe it works by getting into the tumor cells and causing them to self-destruct. But the exact mechanism by which it works is not totally clear. It's not useful for people who have a primary melanoma. The treatment of primary melanoma is surgical excision ,"he said. "It's useful to inject tumors for people who have recurrences; when the primary treatment has failed and when recurrence in the area, or at more distant sites has occurred." About 90 percent of Australians who develop melanoma survive thanks to early diagnosis and treatment. If left untreated, however, the disease can be fatal. Convincing younger people in Australia about the dangers of overexposure to the sun is a battle campaigners are constantly waging. Veronica Manock, a 21-year-old student, had two major operations to remove a cancerous tumor from her leg. "I've had a lot of friends who just said 'I thought it was just, you know, I'll get a mole cut out and that's it', whereas I don't think people realize how much danger they're putting themselves into and how easy it is to stop something like this happening to you just from doing little things,"said Marock. Other researchers in Australia are investigating genetic treatments to skin cancer. There is a pressing need for such research to produce effective treatments. Australians, the majority of whom are fair-skinned , are four times more likely to develop a melanoma than people in Canada, the United States or Great Britain.

Q: Article: Holiday Inns and McDonald's. both saw unmatched growth in the 1960s. Their growth opened another direct business operation--franchising. These operations have the same general pattern. The franchisor, the parent company, first establishes a successful retail business. As it expands, it sees a profit potential in offering others the right to open similar business under its name. The parent company's methods and means of identification with consumers are included in this right. The parent company supplies skill, and may build and rent stores to franchisees. For these advantages the franchisee pays the franchisor a considerable fee. However, some of the advantages and disadvantages are different. By extending a "proven" marketing method, a parent can profit in several ways. First, the franchisee's purchase price gives the parent an immediate return on the plan. Then the sale of supplies to the franchisee provides a continuing source of profits. As new businesses are added and the company's reputation spreads, the values of the franchise increases and sales of franchises become easier. The snowballing effect can be dramatic. Such growth, too, bring into play the economies of scale. Regional or national advertising that might be financially impossible for a franchisor with 20 franchises could be profitable for one with 40. The parent, then, finds immediate gains from the opportunity to expand markets on the basis of reputation alone, without having to put up capital or take the risk of owning retail stores. Added to this advantage is a less obvious but material one, Skilled, responsible retail managers are rare. People who invest their capital in franchises, though, probably come closer to the ideal than do paid managers. In fact, the franchisee is an independent store operator working for the franchisor, but without an independent's freedom to drop supplies at will. Of course the factory's costs of selling supplies are less. But also certainly the franchisee buying goods that have had broad consumer acceptance will not casually change supplies, even when the contract permits. If the hamburger is not what the customer expected, they may not return. Having paid for the goodwill, the franchisee won't thoughtlessly destroy it.

A: Franchising refers to a business operation in which a successful parent company _ .
