Sea turtles migrate across thousands of miles of o...

Sea turtles migrate across thousands of miles of ocean before returning to nest on the same stretch of coastline where they hatched, but how they do this has mystified scientists for more than fifty years. Sea turtles likely go to great lengths to find the places where they began life because successful nesting requires a combination of environmental features that are rare: soft sand, the right temperature, few predators, and an easily accessible beach. From this passage it is safe to conclude that sea turtles

A、are not easily observed by scientists.

B、cannot lay their eggs on any beach other than the one on which they hatched.

C、will not lay their eggs on beaches with pebbly sand.

D、must have the ability to precisely detect their location.

About a minute after taking off from New York’s La Guardia Airport on January 15, 2009, US Airways Flight 1549 collided with a flock of geese. Crippled by the bird strike, both engines lost power and went quiet, forcing Captain Sullenberger to make an emergency landing. When air traffic controllers instructed the seasoned pilot to head for nearby Teterboro Airport, he calmly informed them that he was “unable” to reach a runway. “We’re gonna be in the Hudson,” he said simply, and then told the 150 terrified passengers and five crew members on board to brace for impact. Ninety seconds later, Sullenberger glided the Airbus 320 over the chilly surface of the Hudson River, where it splashed down. As flight attendants ushered passengers into life jackets, through emergency exits and onto the waterlogged wings of the bobbing jet, rescue vessels hastened to the scene. One survivor suffered two broken legs and others were treated for minor injuries or hypothermia, but no fatalities occurred. After walking up and down the aisle twice to ensure a complete evacuation, Sullenberger was the last to leave the sinking plane. The passage implies

A、Sullenberger could possibly have reached the Teterboro Airport, but did not want to risk it.

B、the flight attendants acted as heroically as the pilot.

C、that Sullenberger’s experience contributed to his success in dealing with the emergency.

D、many passengers had to wait in the water before help could arrive.
