Problem: Antenna (radio):

For instance, a phased array consists of two or more simple antennas which are connected together through an electrical network. This often involves a number of parallel dipole antennas with a certain spacing. Depending on the relative phase introduced by the network, the same combination of dipole antennas can operate as a "broadside array" (directional normal to a line connecting the elements) or as an "end-fire array" (directional along the line connecting the elements). Antenna arrays may employ any basic (omnidirectional or weakly directional) antenna type, such as dipole, loop or slot antennas. These elements are often identical.

How many antenna would make up a phased array?
---
A: two or more


Problem: Sichuan:

Garzê Tibetan Autonomous Prefecture and Ngawa Tibetan and Qiang Autonomous Prefecture in western Sichuan are populated by Tibetans and Qiang people. Tibetans speak the Khams and Amdo Tibetan, which are Tibetic languages, as well as various Qiangic languages. The Qiang speak Qiangic languages and often Tibetic languages as well. The Yi people of Liangshan Yi Autonomous Prefecture in southern Sichuan speak the Nuosu language, which is one of the Lolo-Burmese languages; Yi is written using the Yi script, a syllabary standardized in 1974. The Southwest University for Nationalities has one of China's most prominent Tibetology departments, and the Southwest Minorities Publishing House prints literature in minority languages. In the minority inhabited regions of Sichuan, there is bi-lingual signage and public school instruction in non-Mandarin minority languages.

In what year was the language of the Mandarin people standardized?
---
A: unanswerable


Problem: Near East:

In 1853 the Russian Empire on behalf of the Slavic Balkan states began to question the very existence of the Ottoman Empire. The result was the Crimean War, 1853–1856, in which the British Empire and the French Empire supported the Ottoman Empire in its struggle against the incursions of the Russian Empire. Eventually, the Ottoman Empire lost control of the Balkan region.

When was the Crimean War?
---
A: 1853–1856


Problem: Spectre (2015 film):

Filming started in Austria in December 2014, with production taking in the area around Sölden—including the Ötztal Glacier Road, Rettenbach glacier and the adjacent ski resort and cable car station—and Obertilliach and Lake Altaussee, before concluding in February 2015. Scenes filmed in Austria centred on the Ice Q Restaurant, standing in for the fictional Hoffler Klinik, a private medical clinic in the Austrian Alps. Filming included an action scene featuring a Land Rover Defender Bigfoot and a Range Rover Sport. Production was temporarily halted first by an injury to Craig, who sprained his knee whilst shooting a fight scene, and later by an accident involving a filming vehicle that saw three crew members injured, at least one of them seriously.

What part of his body did Craig injure?
---
A:
knee
