Context paragraphs:
Operation Eagle Claw: Operation Eagle Claw (or Operation Evening Light or Operation Rice Bowl) known as Operation Tabas (Persian: عملیات طبس‎ ‎ ) in Iran was a United States Armed Forces operation ordered by US President Jimmy Carter to attempt to end the Iran hostage crisis by rescuing 52 embassy staff held captive at the Embassy of the United States, Tehran on 24 April 1980.  Its failure, and the humiliating public debacle that ensued, damaged US prestige worldwide.  Carter himself blamed his loss in the 1980 US presidential election mainly on his failure to win the release of U.S. hostages held captive in Iran.

Captive white tigers: Captive white tigers are of little known lineage.  They are held captive around the world, usually for financial purposes.  The Tiger Species Survival Plan devised by the Association of Zoos and Aquariums has condemned the breeding of white tigers.  The genes responsible for white colour are represented by 0.001% of the tiger population.  However, in 2008–2009, a closing stock of 264 Bengal tigers and 100 white Bengal tigers were accounted for in Indian zoos.  The disproportionate growth in numbers of the latter points to the relentless inbreeding resorted to among homozygous recessive individuals for selectively multiplying the white animals.  This progressively increasing process will eventually lead to inbreeding depression and loss of genetic variability.

Kamen Rider Build: Ten years ago, a mysterious artifact nicknamed the "Pandora Box" was found on Mars and brought to Earth.  But during a conference of its discovery, the Pandora Box was activated and caused an upheaval in the form of a Skywall that divided Japan into three regions: Seito in the west, Hokuto in the north, and Touto in the east.  In present day, a genius physicist named Sento Kiryu is hired by the government-funded Touto Institute of Advanced Matter Physics in uncovering the secrets of the Pandora Box.  But Sento, having no memory of his past other than being held captive by the mysterious Night Rogue of the Faust organization, secretly moonlights on the side as Kamen Rider Build to fight the Smash monsters that are created by Faust's experimentations.  He is joined by Misora Isurugi who can purify Smash Elements, her father Souichi, and a fugitive named Ryuga Banjo who was held captive by Faust before he escaped and labeled a murderer.

Key retainer: A key retainer device (KRD) is a small metal unit that is wall or door mounted, usually designed for the interchangeable core that retains one key (Key A) while the second key (Key B) is used for authorized purposes.  When the key in use (Key B) is returned into the key retainer, the key held captive (Key A) is turned and then can be released.  Now, the special key, perhaps top master (Key B) is held captive again.  The key retainer is a method for providing visual key control.

Sangeen Zadran: Mullah Sangeen Zadran was an Afghan militant and shadow governor of Paktika province.  Zadran was an operational commander of the Haqqani network, an Islamist insurgent group.  He was held responsible for the capture of American soldier Bowe Bergdahl.  In 2011, he was added to the list of specially designated global terrorists by the United States of America.
