Problem: Please answer a question about the following article about Textual criticism:
Although Greg argued that an editor should be free to use his judgment to choose between competing substantive readings, he suggested that an editor should defer to the copy-text when "the claims of two readings ... appear to be exactly balanced. ... In such a case, while there can be no logical reason for giving preference to the copy-text, in practice, if there is no reason for altering its reading, the obvious thing seems to be to let it stand." The "exactly balanced" variants are said to be indifferent.
Are there times when an editor's judgement should be deferred?
A: the claims of two readings ... appear to be exactly balanced


Question: Read this and answer the question

Though Han wooden structures decayed, some Han-dynasty ruins made of brick, stone, and rammed earth remain intact. This includes stone pillar-gates, brick tomb chambers, rammed-earth city walls, rammed-earth and brick beacon towers, rammed-earth sections of the Great Wall, rammed-earth platforms where elevated halls once stood, and two rammed-earth castles in Gansu. The ruins of rammed-earth walls that once surrounded the capitals Chang'an and Luoyang still stand, along with their drainage systems of brick arches, ditches, and ceramic water pipes. Monumental stone pillar-gates, twenty-nine of which survive from the Han period, formed entrances of walled enclosures at shrine and tomb sites. These pillars feature artistic imitations of wooden and ceramic building components such as roof tiles, eaves, and balustrades.

What were the walls that encompassed the city of Luoyang comprised of?
Answer: rammed-earth


Problem: In the early Heian period, the late 8th and early 9th centuries, Emperor Kammu sought to consolidate and expand his rule in northern Honshū, but the armies he sent to conquer the rebellious Emishi people lacked motivation and discipline, and failed in their task.[citation needed] Emperor Kammu introduced the title of sei'i-taishōgun (征夷大将軍) or Shogun, and began to rely on the powerful regional clans to conquer the Emishi. Skilled in mounted combat and archery (kyūdō), these clan warriors became the Emperor's preferred tool for putting down rebellions.[citation needed] Though this is the first known use of the "Shogun" title, it was a temporary title, and was not imbued with political power until the 13th century. At this time (the 7th to 9th century) the Imperial Court officials considered them merely a military section under the control of the Imperial Court.
Who did Kammu fail to conquer?
The answer is the following: Emishi


Investitures, which include the conferring of knighthoods by dubbing with a sword, and other awards take place in the palace's Ballroom, built in 1854.

Problem: Please answer a question about the following article about Portugal:
Administratively, Portugal is divided into 308 municipalities (Portuguese: municípios or concelhos), which after a reform in 2013 are subdivided into 3,092 civil parishes (Portuguese: freguesia). Operationally, the municipality and civil parish, along with the national government, are the only legally identifiable local administrative units identified by the government of Portugal (for example, cities, towns or villages have no standing in law, although may be used as catchment for the defining services). For statistical purposes the Portuguese government also identifies NUTS, inter-municipal communities and informally, the district system, used until European integration (and being phased-out by the national government).[original research?] Continental Portugal is agglomerated into 18 districts, while the archipelagos of the Azores and Madeira are governed as autonomous regions; the largest units, established since 1976, are either mainland Portugal (Portuguese: Portugal Continental) and the autonomous regions of Portugal (Azores and Madeira).
How many districts is the continental Portugal divided into?
A:
18
