[EX Q]: story: CHAPTER III

_Danny Meadow Mouse Plays Hide and Seek_

Life is always a game of hide and seek to Danny Meadow Mouse. You see, he is such a fat little fellow that there are a great many other furry-coated people, and almost as many who wear feathers, who would gobble Danny up for breakfast or for dinner if they could. Some of them pretend to be his friends, but Danny always keeps his eyes open when they are around and always begins to play hide and seek. Peter Rabbit and Jimmy Skunk and Striped Chipmunk and Happy Jack Squirrel are all friends whom he can trust, but he always has a bright twinkling eye open for Reddy Fox and Billy Mink and Shadow the Weasel and old Whitetail the Marsh Hawk, and several more, especially Hooty the Owl at night.

Now Danny Meadow Mouse is a stout-hearted little fellow, and when rough Brother North Wind came shouting across the Green Meadows, tearing to pieces the snow clouds and shaking out the snowflakes until they covered the Green Meadows deep, deep, deep, Danny just snuggled down in his warm coat in his snug little house of grass and waited. Danny liked the snow. Yes, sir, Danny Meadow Mouse liked the snow. He just loved to dig in it and make tunnels. Through those tunnels in every direction he could go where he pleased and when he pleased without being seen by anybody. It was great fun!

Every little way he made a little round doorway up beside a stiff stalk of grass. Out of this he could peep at the white world, and he could get the fresh cold air. Sometimes, when he was quite sure that no one was around, he would scamper across on top of the snow from one doorway to another, and when he did this, he made the prettiest little footprints. , question: What was the advantage of snow tunnels?
[EX A]: he could go where he pleased without being seen

[EX Q]: story: Beijing (CNN) -- The wife of Ai Weiwei was taken from the Chinese artist's studio by police Tuesday and was questioned for three hours, the high-profile dissident said.

Four policemen took Lu Qing from the Beijing studio to a nearby police station, he said.

She was released by police after questioning and is now a "criminal suspect," he said.

They have not told her what crimes she is accused of, he added.

"I think the authorities are trying to threaten me through her," he said, speculating that Lu's arrest was related to her plans to visit Taiwan for an exhibition of her husband's work.

She has now been told to stay in Beijing, he added.

Police did not respond to a CNN request for comment on the case.

"Nobody can consider himself safe or innocent in an environment like this," said the dissident, who was himself detained by police for 81 days earlier this year.

He was ultimately charged with tax evasion, and last week paid $1.3 million so he can contest the charges brought against his company, Fake Cultural Development Ltd.

Had he not paid the sum, his wife -- who legally represents the company -- would have been jailed, he said.

The government says the company owes 15 million yuan ($2.3 million). The money was raised from 30,000 contributors, he said.

His lawyer, Pu Zhiqiang, said last week that Ai intends to return the donations if he wins the case and is refunded the money.

His family and human rights advocates believe that the real reason for his imprisonment is his criticism of the Chinese government. , question: what happened to his wife?
[EX A]: she was questioned by police
