问题     It was low tide on Cape Cod, and coastal naturalist Dick Hilmer was getting his feet wet a half mile off the Brewster shoreline. "Cape Cod was formed by glaciers 18,000 years ago," he told his small audience of journalists. "A mile-high sheet of ice moved down from the top of the world, and as it dropped rocks they formed the Cape. As the glacier went north, a mile and a half of sand dropped into Cape Cod Bay".
    And that is why current visitors to the Cape can walk so far out on the tidal flats at low tide, and stroll along 40 miles of sandy beaches that are now part of the U.S. National Seashore. As we walked, Hilmer pointed out the life all around us, from strands of sea lettuce to hermit crabs to periwinkles. The kids picked up razor clams, quahogs and other ephemera, some of it delightfully alive.
    Red tide (Alexandrium fundyense) on the Cape and north as far as Isle au Haut in Maine caused great damage to many of these sea lives in 2005. It was the most widespread outbreak since 1972. Red tide produces a potent neurotoxin that accumulates in the tissue of bivalves (双壳类), and while it doesn’t harm its host it can cause paralysis or respiratory problems for seafood fans. Many clam, oyster and mussel beds were shut down as a result. It’s unclear what causes the phenomenon.
    Cape Cod extends 65 miles out into the Atlantic, making its tip the easternmost point in the U. S.. It’s shaped like a bending arm, and it covers 399 square miles with 15 distinct towns. Brewster is in the Lower Cape, on the bay side of the Cape’s elbow. It’s home to Ocean Edge, a rambling resort hotel that employs Hilmer to teach visitors about the natural history of the region.
    Ocean Edge was originally a lavish private home owned by the Nickerson family. Built in 1890 and then rebuilt after a 1906 fire. But now it throws its doors open to vacationing families.
    Ocean Edge has its own 18-hole golf course (being renovated by Nicklaus Design), bike trails, tennis courts, swimming pools and private beach). The 335-room facility is undergoing a $5 million improvement project this year, with the aim of making it attractive to visitors in the "shoulder" seasons around the high months of July and August. Two-day "Explore" hotel packages, including a pair of whale watch tickets and breakfast are $464 to $664, depending on the season. [br] The length of Cape Cod is ______.
选项 A、399 miles
B、a mile
C、40 miles
D、65 miles
