Two common considerations have the Latin names lectio brevior (shorter reading) and lectio difficilior (more difficult reading). The first is the general observation that scribes tended to add words, for clarification or out of habit, more often than they removed them. The second, lectio difficilior potior (the harder reading is stronger), recognizes the tendency for harmonizationresolving apparent inconsistencies in the text. Applying this principle leads to taking the more difficult (unharmonized) reading as being more likely to be the original. Such cases also include scribes simplifying and smoothing texts they did not fully understand.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is the main principle of lectio difficilior?
Ah, so.. the tendency for harmonizationresolving apparent inconsistencies in the text.

Westminster diocese was dissolved in 1550, but the abbey was recognised (in 1552, retroactively to 1550) as a second cathedral of the Diocese of London until 1556. The already-old expression "robbing Peter to pay Paul" may have been given a new lease of life when money meant for the abbey, which is dedicated to Saint Peter, was diverted to the treasury of St Paul's Cathedral.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who isn't the abbey dedicated to?
Ah, so.. unanswerable

Due to the work nature of airline pilots, who often cross several timezones and regions of sunlight and darkness in one day, and spend many hours awake both day and night, they are often unable to maintain sleep patterns that correspond to the natural human circadian rhythm; this situation can easily lead to fatigue. The NTSB cites this as contributing to many accidents[unreliable medical source?] and has conducted several research studies in order to find methods of combating fatigue in pilots.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who follows a very natural human circadian rhythem?
Ah, so..
unanswerable
