input: Vacuum is space void of matter. The word stems from the Latin adjective vacuus for "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often discuss ideal test results that would occur in a perfect vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is lower than atmospheric pressure. The Latin term in vacuo is used to describe an object as being in what would otherwise be a vacuum. 

The quality of a partial vacuum refers to how closely it approaches a perfect vacuum. Other things equal, lower gas pressure means higher-quality vacuum. For example, a typical vacuum cleaner produces enough suction to reduce air pressure by around 20%. Much higher-quality vacuums are possible. Ultra-high vacuum chambers, common in chemistry, physics, and engineering, operate below one trillionth (10−12) of atmospheric pressure (100 nPa), and can reach around 100 particles/cm3. Outer space is an even higher-quality vacuum, with the equivalent of just a few hydrogen atoms per cubic meter on average. According to modern understanding, even if all matter could be removed from a volume, it would still not be "empty" due to vacuum fluctuations, dark energy, transiting gamma rays, cosmic rays, neutrinos, and other phenomena in quantum physics. In the electromagnetism in the 19th century, vacuum was thought to be filled with a medium called aether. In modern particle physics, the vacuum state is considered the ground state of matter. 1.

question: CHAPTER XX. 

TO-MORROW. 

The two girls met no living soul on their way back to the rectory. They let themselves in noiselessly; they stole upstairs unheard--the breaking morning gave them what light they needed. Shirley sought her couch immediately; and though the room was strange--for she had never slept at the rectory before--and though the recent scene was one unparalleled for excitement and terror by any it had hitherto been her lot to witness, yet scarce was her head laid on the pillow ere a deep, refreshing sleep closed her eyes and calmed her senses. 

Perfect health was Shirley's enviable portion. Though warm-hearted and sympathetic, she was not nervous; powerful emotions could rouse and sway without exhausting her spirit. The tempest troubled and shook her while it lasted, but it left her elasticity unbent, and her freshness quite unblighted. As every day brought her stimulating emotion, so every night yielded her recreating rest. Caroline now watched her sleeping, and read the serenity of her mind in the beauty of her happy countenance. 

For herself, being of a different temperament, she could not sleep. The commonplace excitement of the tea-drinking and school-gathering would alone have sufficed to make her restless all night; the effect of the terrible drama which had just been enacted before her eyes was not likely to quit her for days. It was vain even to try to retain a recumbent posture; she sat up by Shirley's side, counting the slow minutes, and watching the June sun mount the heavens.

Question: (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."  1. Who has been holding John Cantlie?
2. Is he there against his will?
3. How long has he been there?
4. Where is he from?
5. What was his job?
6. When was he taken?
7. What month?

12. What does he claim Isis is controlling the majority of? Provide a numbered list of answers.
