Input: 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 procès-verbal; but a procès-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.

What amendment process is generally reserved for changes that rectify obvious errors in the text?
Output: a procès-verbal

Input: Brain
From an evolutionary-biological perspective, the function of the brain is to provide coherent control over the actions of an animal. A centralized brain allows groups of muscles to be co-activated in complex patterns; it also allows stimuli impinging on one part of the body to evoke responses in other parts, and it can prevent different parts of the body from acting at cross-purposes to each other.

The function of the brain from an evolutionary-biological thought is what?
Output: provide coherent control over the actions of an animal

Input: Planck constant
Bohr also introduced the quantity , now known as the reduced Planck constant, as the quantum of angular momentum. At first, Bohr thought that this was the angular momentum of each electron in an atom: this proved incorrect and, despite developments by Sommerfeld and others, an accurate description of the electron angular momentum proved beyond the Bohr model. The correct quantization rules for electrons – in which the energy reduces to the Bohr model equation in the case of the hydrogen atom – were given by Heisenberg's matrix mechanics in 1925 and the Schrödinger wave equation in 1926: the reduced Planck constant remains the fundamental quantum of angular momentum. In modern terms, if J is the total angular momentum of a system with rotational invariance, and Jz the angular momentum measured along any given direction, these quantities can only take on the values

Who helped to give the correct quantization rules for electrons in 1926?
Output: Schrödinger

Input: Royal Dutch Shell
On 16 March 2012, 52 Greenpeace activists from five different countries boarded Fennica and Nordica, multipurpose icebreakers chartered to support Shell's drilling rigs near Alaska. Around the same time period, a reporter for Fortune magazine spoke with Edward Itta, an Inupiat Eskimo leader and the former mayor of the North Slope Borough, who expressed that he was conflicted about Shell's plans in the Arctic, as he was very concerned that an oil spill could destroy the Inupiat Eskimo's hunting-and-fishing culture, but his borough also received major tax revenue from oil and gas production; additionally, further revenue from energy activity was considered crucial to the future of the living standard in Itta's community.

How many countries did the group of Greenpeace activists represent?
Output:
five
