多选题 Although the development of new infrastructure (such public facilities as power plants, schools, and bridges) is usually determined by governmental planning, {{U}}sometimes this development can be planned more flexibly and realistically by private investors{{/U}} who anticipate profit from the collection of user fees. Such profits can contribute to the financing of more infrastructure if demand proves great enough, whereas the reluctance of developers to invest in such projects can signal that additional infrastructure is not needed. During the economic boom of the 1980's, for example, the state of Virginia authorized private developers to build a $300 million toll road.
The passage implies that the "governmental planning" mentioned in line 4 may lead to which of the following problems?

• A. Improper use of profits derived from user fees.
• B. Unduly slow development of necessary new infrastructure.
• C. Unrealistic decisions about developing new infrastructure.
• D. Incorrect predictions about profits to be gained from user fees.
• E. Obstruction of private financing for the development of new infrastructure.
