Problem: Treaty:

There are three ways an existing treaty can be amended. First, formal amendment requires State parties to the treaty to go through the ratification process all over again. The re-negotiation of treaty provisions can be long and protracted, and often some parties to the original treaty will not become parties to the amended treaty. When determining the legal obligations of states, one party to the original treaty and one a party to the amended treaty, the states will only be bound by the terms they both agreed upon. Treaties can also be amended informally by the treaty executive council when the changes are only procedural, technical change in customary international law can also amend a treaty, where state behavior evinces a new interpretation of the legal obligations under the treaty. Minor corrections to a treaty may be adopted by a proces-verbal; but a proces-verbal is generally reserved for changes to rectify obvious errors in the text adopted, i.e. where the text adopted does not correctly reflect the intention of the parties adopting it.

Problem: Unit testing is a software development process that involves synchronized application of a broad spectrum of defect prevention and detection strategies in order to reduce software development risks, time, and costs. It is performed by the software developer or engineer during the construction phase of the software development lifecycle. Rather than replace traditional QA focuses, it augments it. Unit testing aims to eliminate construction errors before code is promoted to QA; this strategy is intended to increase the quality of the resulting software as well as the efficiency of the overall development and QA process.
Who performs the Unit testing phase?
---
Answer: software developer or engineer

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the 7th century, the Frankish merchant Samo, who supported the Slavs fighting their Avar rulers, became the ruler of the first known Slav state in Central Europe, which, however, most probably did not outlive its founder and ruler. This provided the foundation for subsequent Slavic states to arise on the former territory of this realm with Carantania being the oldest of them. Very old also are the Principality of Nitra and the Moravian principality (see under Great Moravia). In this period, there existed central Slavic groups and states such as the Balaton Principality, but the subsequent expansion of the Magyars, as well as the Germanisation of Austria, separated the northern and southern Slavs. The First Bulgarian Empire was founded in 681, the Slavic language Old Bulgarian became the main and official of the empire in 864. Bulgaria was instrumental in the spread of Slavic literacy and Christianity to the rest of the Slavic world.
What Frankish merchant was the ruler of the first Slav state in Central Europe?
A: Samo

Context and question: In South Africa, charities issue a tax certificate when requested by donors which can be used as a tax deduction by the donor. Non Profit Organisations are registered under Companies and Intellectual Property Commission as Nonprofit Companies (NPCs) but may voluntarily register with The Nonprofit Companies Directorate. Trusts are registered by the Master of the High Court. Section 21 Companies are registered under the Company's Act. All are classified as Voluntary Organisations and all must be registered with the South Africa Revenue Services "SARS".[citation needed]
Who would a South Africian NPO register with if they were a voluntary organization?
Answer: South Africa Revenue Services "SARS"

Question: Music was an important part of both secular and spiritual culture, and in the universities it made up part of the quadrivium of the liberal arts. From the early 13th century, the dominant sacred musical form had been the motet; a composition with text in several parts. From the 1330s and onwards, emerged the polyphonic style, which was a more complex fusion of independent voices. Polyphony had been common in the secular music of the Provencal troubadours. Many of these had fallen victim to the 13th-century Albigensian Crusade, but their influence reached the papal court at Avignon.
Is there an answer to this question: What was the dominant sacred musical form in the early 13th century?

Answer: the motet

Due to many centuries of intensive settlement, most of the area is shaped by human influence. The original natural vegetation of Thuringia is forest with beech as its predominant species, as can still be found in the Hainich mountains today. In the uplands, a mixture of beech and spruce would be natural. However, most of the plains have been cleared and are in intensive agricultural use while most of the forests are planted with spruce and pine. Since 1990, Thuringia's forests have been managed aiming for a more natural and tough vegetation more resilient to climate change as well as diseases and vermin. In comparison to the forest, agriculture is still quite conventional and dominated by large structures and monocultures. Problems here are caused especially by increasingly prolonged dry periods during the summer months.
