((4)) the importance of the project or class of projects in relation to other projects or classes of projects that may be in competition for the same amounts;
((5)) the prospects that the project for which assistance is sought will improve, on a continuing rather than a temporary basis, the opportunities for employment, the average level of income, or the economic and social development of the area served by the project; and
