['The direct application of innovations is not the only way in which technology is radically improving the quality of life in some communities.', 'The only ways in which technology is radically improving the quality of life in some communities are by creating jobs, adding to the tax base, and contributing to an upbeat spirit of renewal.', 'Companies involved in the design, production, testing, and marketing of new technology create jobs, add to the tax base, and contribute to an upbeat spirit of renewal.', 'Either the creation or the direct application of technological innovations is radically improving the quality of life in most communities.']
