Question: As is known from the "Sumerian Farmer's Almanac", after the flood season and after the Spring Equinox and the Akitu or New Year Festival, using the canals, farmers would flood their fields and then drain the water. Next they made oxen stomp the ground and kill weeds. They then dragged the fields with pickaxes. After drying, they plowed, harrowed, and raked the ground three times, and pulverized it with a mattock, before planting seed. Unfortunately the high evaporation rate resulted in a gradual increase in the salinity of the fields. By the Ur III period, farmers had switched from wheat to the more salt-tolerant barley as their principal crop.
Is there an answer to this question: When would farmers flood their fields?

Answer: after the Spring Equinox and the Akitu


Question: The language of treaties, like that of any law or contract, must be interpreted when the wording does not seem clear or it is not immediately apparent how it should be applied in a perhaps unforeseen circumstance. The Vienna Convention states that treaties are to be interpreted "in good faith" according to the "ordinary meaning given to the terms of the treaty in their context and in the light of its object and purpose." International legal experts also often invoke the 'principle of maximum effectiveness,' which interprets treaty language as having the fullest force and effect possible to establish obligations between the parties.
Is there an answer to this question: Besides unclear language what might also arise that necessitates the interpretation of the language of a treaty?

Answer: a perhaps unforeseen circumstance


Question: The evolution of Proto-Greek should be considered within the context of an early Paleo-Balkan sprachbund that makes it difficult to delineate exact boundaries between individual languages. The characteristically Greek representation of word-initial laryngeals by prothetic vowels is shared, for one, by the Armenian language, which also seems to share some other phonological and morphological peculiarities of Greek; this has led some linguists to propose a hypothetical closer relationship between Greek and Armenian, although evidence remains scant.
Is there an answer to this question: What progression coincided with the the early Greek states that makes it difficult to give credit for the language and differences ? 

Answer: Paleo-Balkan sprachbund that makes it difficult to delineate exact boundaries between individual languages.


Question: Music fans have turned to Change.org around the globe to try and block West's participation at various events. The largest unsuccessful petition has been to the Glastonbury Festival 2015 with 133,000+ voters stating they would prefer a rock band to headline. On July 20, 2015, within five days of West's announcement as the headlining artist of the closing ceremonies of the 2015 Pan American Games, Change.org user XYZ collected over 50,000 signatures for West's removal as headliner citing the headlining artist should be Canadian. In his Pan American Games Closing Ceremony performance, close to the end of his performance, West closed the show by tossing his faulty microphone in the air and walked off stage.
