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 Output:
she was questioned by police

story: Oakland is the largest city and the county seat of Alameda County, California, United States. A major West Coast port city, Oakland is the largest city in the East Bay region of the San Francisco Bay Area, the third largest city overall in the San Francisco Bay Area, the eighth largest city in California, and the 45th largest city in the United States, with a population of 419,267 . It serves as a trade center for the San Francisco Bay Area; its Port of Oakland is the busiest port in the San Francisco Bay, the entirety of Northern California, and the fifth busiest in the United States of America. The city was incorporated in 1852. 

Oakland's territory covers what was once a mosaic of California coastal terrace prairie, oak woodland, and north coastal scrub. Its land served as a rich resource when its hillside oak and redwood timber were logged to build San Francisco, and Oakland's fertile flatland soils helped it become a prolific agricultural region. In the late 1860s, Oakland was selected as the western terminal of the Transcontinental Railroad. Following the 1906 San Francisco earthquake, many San Francisco citizens moved to Oakland, enlarging the city's population, increasing its housing stock and improving its infrastructure. It continued to grow in the 20th century with its busy port, shipyards, and a thriving automobile manufacturing industry., question: What is its rank of size in the state?

Ex Output:
It is the eight largest city in California

story: So, there was this kid named Jack that came up to my beanstalk one day. I couldn't believe my eyes, so I put down my ham sandwich I was eating and looked at him. I'm not sure what he thought he was doing there, but he sure did talk a lot. He kept asking me questions about this and then he asked me some questions about that and I was getting a little bit tired of all of the questions. 

When I thought I wouldn't hear the end of everything, this Jack kid asked me about the one and only secret that I've always kept to myself. That no one even knew about! No, it wasn't about my golden guitar or even my goose that laid eggs filled with coins. No, he was asking me about my beans and their roots. 

You see, I'm a giant and my job is to make sure the bean roots that we use to get down to earth are well protected and guarded. They're what helps us get down to the little person world when we need to. I became a little bit worried as the little kid asked more and more questions about my roots. I didn't want to tell him that my roots were hidden in the library! 

I walked over to him to pick this little kid up to get him to quiet down about the bean roots, well, he got me with his little knife and I dropped him! Thankfully, he didn't get hurt or I would've been so sad! 

He ran down the beanstalk when I chased after him. I guess he wanted to get back to his little people. I didn't follow him, but I sure hope he doesn't come back for my stuff., question: About what?

Ex Output:

about this and that
