Input: Consider Input: 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 name?

Input: Consider Input: story: Maurice Mountain is a retired lawyer in Washington, D.C. He developed a prototype for a device he calls the Presto Emergency Boat Ladder. His invention is a small folding ladder that attaches to the side of a boat to help people who fall into the water. Mr. Mountain plans to mass-produce his boat ladder.

He created his invention at a workshop called TechShop. Mr. Mountain says, "I think it encourages innovation. I think people who probably have had ideas rolling around in the back of their minds for years but have never had the opportunity to actually put them into production or even experiment with them would find this place wonderful. Members of TechShop use high-tech equipment to develop and produce ideas they have for inventions." Isabella Musachio manages a TechShop in Arlington, Virginia. She says the shop has many different kinds of equipment.

"TechShop is a do-it-yourself maker space. So when you come in we have all these different areas of the shop, and we have a metal shop, wood shop, lasers, 3D printers, electronics. I mean, we have so many different areas and we have all the equipment that is availahle to anybody above the age of 12."

Membership costs for TechShop start at just over $ 100 per month. Members are able to use costly machines including 3D modeling tools and laser cutters. Isabella Musachio says TechShop helps its members build their dreams.

"Our motto is 'build your dreams here' because you can really come in with just an idea, and then with the help of TechShop make that leap from an idea to building your project o, your prototype or even your business."

Jim Newton is the founder of TechShop. He first introduced the idea for the technology workshops at an arts and sciences event called Maker Faire in San Mateo, California in 2006. His idea attracted hundreds of members during that event, Now, there are eight TechShop locations in the U. S. In all, there are more than 6,000 members. Two more-TechShop locations in the cities of St. Louis and Look Angeles will be set up., question: Who designed something?

Input: Consider Input: 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?
Output: she was questioned by police
