Here is a question about this article: 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 is the answer to this question: How many ways are there to amend an existing treaty?
****
So... three

Problem: Please answer a question about the following article about Culture:
Cultural sociology first emerged in Weimar Germany (1918–1933), where sociologists such as Alfred Weber used the term Kultursoziologie (cultural sociology). Cultural sociology was then "reinvented" in the English-speaking world as a product of the "cultural turn" of the 1960s, which ushered in structuralist and postmodern approaches to social science. This type of cultural sociology may loosely be regarded as an approach incorporating cultural analysis and critical theory. Cultural sociologists tend to reject scientific methods,[citation needed] instead hermeneutically focusing on words, artifacts and symbols. "Culture" has since become an important concept across many branches of sociology, including resolutely scientific fields like social stratification and social network analysis. As a result, there has been a recent influx of quantitative sociologists to the field. Thus there is now a growing group of sociologists of culture who are, confusingly, not cultural sociologists. These scholars reject the abstracted postmodern aspects of cultural sociology, and instead look for a theoretical backing in the more scientific vein of social psychology and cognitive science. "Cultural sociology" is one of the largest sections of the American Sociological Association. The British establishment of cultural studies means the latter is often taught as a loosely distinct discipline in the UK.
Where did sociology culture stem from?
A: Weimar Germany

Problem: Meanwhile, Kerry's staff began their own investigations and, on October 14, issued a report that exposed illegal activities on the part of Lieutenant Colonel Oliver North, who had set up a private network involving the National Security Council and the CIA to deliver military equipment to right-wing Nicaraguan rebels (Contras). In effect, North and certain members of the President's administration were accused by Kerry's report of illegally funding and supplying armed militants without the authorization of Congress. Kerry's staff investigation, based on a year-long inquiry and interviews with fifty unnamed sources, is said to raise "serious questions about whether the United States has abided by the law in its handling of the contras over the past three years."
What government agencies worked with North?
The answer is the following: the National Security Council and the CIA


Input: Article: The length and nature of parental care varies widely amongst different orders and species. At one extreme, parental care in megapodes ends at hatching; the newly hatched chick digs itself out of the nest mound without parental assistance and can fend for itself immediately. At the other extreme, many seabirds have extended periods of parental care, the longest being that of the great frigatebird, whose chicks take up to six months to fledge and are fed by the parents for up to an additional 14 months. The chick guard stage describes the period of breeding during which one of the adult birds is permanently present at the nest after chicks have hatched. The main purpose of the guard stage is to aid offspring to thermoregulate and protect them from predation.

Now answer this question: What type of seabird has the longest period of parental care?

Output:
frigatebird
