"story": "Traditionally considered the last part of the Stone Age, the Neolithic followed the terminal Holocene Epipaleolithic period and commenced with the beginning of farming, which produced the "Neolithic Revolution". It ended when metal tools became widespread (in the Copper Age or Bronze Age; or, in some geographical regions, in the Iron Age). The Neolithic is a progression of behavioral and cultural characteristics and changes, including the use of wild and domestic crops and of domesticated animals. 

The beginning of the Neolithic culture is considered to be in the Levant (Jericho, modern-day West Bank) about 10,200 – 8,800 BC. It developed directly from the Epipaleolithic Natufian culture in the region, whose people pioneered the use of wild cereals, which then evolved into true farming. The Natufian period was between 12,000 and 10,200 BC, and the so-called "proto-Neolithic" is now included in the Pre-Pottery Neolithic (PPNA) between 10,200 and 8,800 BC. As the Natufians had become dependent on wild cereals in their diet, and a sedentary way of life had begun among them, the climatic changes associated with the Younger Dryas are thought to have forced people to develop farming."
Solution: What did Neolithic follow?
Why? This question is based on the following sentence in the passage - the Neolithic followed the terminal Holocene Epipaleolithic period and this is answerable from the passage. So, it is a good question.

New input: 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. 
Solution:
What is Ai WeiWei's company called?
