Questions are based on the following passage.
　　Large companies need a way to reach the savings of the public at large. The same problem, on asmaller scale, faces practically every company, trying to develop new products and create new jobs.There can be little prospect of raising the sort of sums needed from friends and people we know, andwhile banks may agree to provide short-term finance, they are generally unwilling to provide money ona permanent basis for long-term projects. So companies turn to the public, inviting people to lend themmoney, or take a share in the business in exchange for a share in future profits. This they do by issuingstocks and shares in the business through the Stock Exchange. By doing so, they can put into circulationthe savings of individual and institutions, both at home and overseas.
　　When the saver needs his money back, he does not have to go to the company with whom he originally placed it. Instead, he sells his shares through a stockbroker to some other saver who is seekingto invest his money.
　　Many of the services needed both by industry and by each of us are provided by the Governmentor by local authorities. Without hospitals, roads, electricity, telephones, railways, this country could notfunction. All these require continuous spending on new equipment and new development if they are to serve us properly, requiring more money than is raised through taxes alone. The Government, localauthorities, and nationalized industries therefore frequently need to borrow money to finance major capital spending, and they too, come to the Stock Exchange.
　　There is hardly a man or woman in this country whose job or whose standard of living does not depend on the ability of his or her employers to raise money to finance new development. In one wayor another, this new money must come from the savings of the country. The Stocky Exchange exists top rovide a channel through which these savings can reach those who need finance.
