Example Input: 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.

Example Input: A bracket is a tall punctuation mark typically used in matched pairs within text, to set apart or interject other text. The matched pair may be described as opening and closing, or left and right symbols. 

Forms include round (also called "parentheses"), square, curly (also called "braces"), and angle brackets (also called "chevrons"); and various other pairs of symbols. 

In addition to referring to the class of all types of brackets, the unqualified word "bracket" is most commonly used to refer to a specific type of bracket: in modern American usage this is usually the square bracket and in modern British usage this is usually the round bracket. 

Chevrons were the earliest type of bracket to appear in written English. Desiderius Erasmus coined the term "lunula" to refer to the rounded parentheses (), recalling the shape of the crescent moon. 

Some of the following names are regional or contextual. 

The characters ‹ › and « », known as guillemets or "angular quote brackets", are actually quotation mark glyphs used in several European languages. Which one of each pair is the opening quote mark and which is the closing quote varies between languages. 

In English, typographers generally prefer to not set brackets in italics, even when the enclosed text is italic. However, in other languages like German, if brackets enclose text in italics, they are usually set in italics too.
Example Output: What was the first form of brackets in written English?

Example Input: (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." 
Example Output:
Who has been holding John Cantlie?
