Example input: "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."
Example output: What did Neolithic follow?
Example explanation: 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.
Q: (CNN) -- ISIS has released a new video of British hostage John Cantlie, this time showing him in the Syrian border city of Kobani. 

In a segment that lasts for more than five minutes, Cantlie argues that -- unlike Western media accounts of recent days -- Kobani is mostly under control of the terror group, which calls itself the Islamic state. 

He claims that ISIS fighters are mopping up, and that the all-out battle for the city is over. Kurdish forces in Syria have said the fight is far from finished, and that Iraqi Kurdish forces will soon be joining them. 

Kurdish forces and ISIS militants have been clashing in the key border city for more than a month. On Sunday, the Syrian Observatory for Human Rights said at least 800 people have been killed there since the fighting started. 

The video posted online Monday is the latest ISIS has released of Cantlie, who's been held hostage for nearly two years. 

The British photojournalist, who also wrote several articles for major British newspapers, was kidnapped in November 2012 along with American journalist James Foley. In the first video of him released by the group last month, Cantlie made clear that he was forced to share a message from ISIS. 

The video released Monday portrays Cantlie as a reporter in the field describing Kobani. The hostage, dressed in black, appears close enough to the border to see Turkish flags in the background. 

"It seemed almost like a standup that a CNN correspondent would do in a foreign city," Peter Bergen, CNN national security analyst, said. "It was designed to show that he's relaxed, that what he's saying is accurate. But clearly he's under duress." 
A:
Who has been holding John Cantlie?
