Input: Nigeria
The Niger Delta Nembe Creek Oil field was discovered in 1973 and produces from middle Miocene deltaic sandstone-shale in an anticline structural trap at a depth of 24 km. In June 2013, the company announced a strategic review of its operations in Nigeria, hinting that assets could be divested. While many international oil companies have operated there for decades, by 2014 most were making moves to divest their interests, citing a range of issues including oil theft. In August 2014, Shell Oil Company said it was finalising its interests in four Nigerian oil fields.

What is the depth of the Niger Delta Nembe Creek Oil field?
Output: 24 km

Input: Imamah (Shia doctrine)
The Shia tariqah with a majority of adherents are the Twelvers who are commonly known as the "Shia". After that come the Nizari Ismailis commonly known as the Ismailis; and then come the Mustalian Ismailis commonly known as the "Bohras" with further schisms within their Bohri tariqah. The Druze tariqah (very small in number today) initially were of the Fatimid Ismailis and separated from them (the Fatimid Ismailis) after the death of the Fatimid Imam and Caliph Hakim Bi Amrillah. The Shia Sevener tariqah no longer exists. Another small tariqah is the Zaidi Shias, also known as the Fivers and who do not believe in The Occultation of their last Imam.

What are the Nizari Ismailis more commonly known as?
Output: Ismailis

Input: Antenna (radio)
As an electro-magnetic wave travels through the different parts of the antenna system (radio, feed line, antenna, free space) it may encounter differences in impedance (E/H, V/I, etc.). At each interface, depending on the impedance match, some fraction of the wave's energy will reflect back to the source, forming a standing wave in the feed line. The ratio of maximum power to minimum power in the wave can be measured and is called the standing wave ratio (SWR). A SWR of 1:1 is ideal. A SWR of 1.5:1 is considered to be marginally acceptable in low power applications where power loss is more critical, although an SWR as high as 6:1 may still be usable with the right equipment. Minimizing impedance differences at each interface (impedance matching) will reduce SWR and maximize power transfer through each part of the antenna system.

Impedance matching makes an important difference in what antenna function?
Output: power transfer

Input: Treaty
No one party to a treaty can impose its particular interpretation of the treaty upon the other parties. Consent may be implied, however, if the other parties fail to explicitly disavow that initially unilateral interpretation, particularly if that state has acted upon its view of the treaty without complaint. Consent by all parties to the treaty to a particular interpretation has the legal effect of adding another clause to the treaty this is commonly called an 'authentic interpretation'.

Consent by all parties to a treaty to a particular interpretation of the treaty has what legal effect?
Output:
adding another clause to the treaty
