Final answer:
The author suggests reexamining the type and quality of parks paid for by federal dollars through an independent commission.
Step-by-step explanation:
The author is suggesting that the type and quality of parks paid for by federal dollars should be reexamined. They propose that an independent commission should review the parks to determine whether they should all be kept open and what level of fees should be charged to park users. Currently, the people who use the parks pay less than ten percent of the operating costs. By conducting a thorough review, the commission can ensure that federal dollars are being used effectively and efficiently to maintain and operate the national parks.
