[单项选择]Landslides happen when large amounts of rock, mud and other loose materials are suddenly uprooted and sent sliding down a slope. This might be caused by an earthquake or it might happen after a heavy rain or when soil becomes waterlogged after a fall of snow.

After dealing with the rats", they turned to birds-and now hundreds of them have been killed in a move to protect rare (稀有) birds. Even cat lovers have been persuaded to back the move, after being told that there was no other choice.
