The problem: Answer a question about this article:
Amensalism is an interaction where an organism inflicts harm to another organism without any costs or benefits received by the other. A clear case of amensalism is where sheep or cattle trample grass. Whilst the presence of the grass causes negligible detrimental effects to the animal's hoof, the grass suffers from being crushed. Amensalism is often used to describe strongly asymmetrical competitive interactions, such as has been observed between the Spanish ibex and weevils of the genus Timarcha which feed upon the same type of shrub. Whilst the presence of the weevil has almost no influence on food availability, the presence of ibex has an enormous detrimental effect on weevil numbers, as they consume significant quantities of plant matter and incidentally ingest the weevils upon it.
What type of relationship is it when large animals crush small plants?
****
The answer: Amensalism


Problem: Please answer a question about the following article about Biodiversity:
A 2007 study conducted by the National Science Foundation found that biodiversity and genetic diversity are codependent—that diversity among species requires diversity within a species, and vice versa. "If any one type is removed from the system, the cycle can break down, and the community becomes dominated by a single species." At present, the most threatened ecosystems are found in fresh water, according to the Millennium Ecosystem Assessment 2005, which was confirmed by the "Freshwater Animal Diversity Assessment", organised by the biodiversity platform, and the French Institut de recherche pour le développement (MNHNP).
What can cause a break down of a biodiversity system?
A: If any one type is removed from the system

After the German occupation of France in 1940, Britain and the empire stood alone against Germany, until the entry of the Soviet Union to the war in 1941. British Prime Minister Winston Churchill successfully lobbied President Franklin D. Roosevelt for military aid from the United States, but Roosevelt was not yet ready to ask Congress to commit the country to war. In August 1941, Churchill and Roosevelt met and signed the Atlantic Charter, which included the statement that "the rights of all peoples to choose the form of government under which they live" should be respected. This wording was ambiguous as to whether it referred to European countries invaded by Germany, or the peoples colonised by European nations, and would later be interpreted differently by the British, Americans, and nationalist movements.

When was the Atlantic Charter signed?
Answer: August 1941


Problem: Much of the medieval period was a time of power struggles between competing dynasties such as the House of Savoy, the Visconti in northern Italy and the House of Habsburg in Austria and Slovenia. In 1291 to protect themselves from incursions by the Habsburgs, four cantons in the middle of Switzerland drew up a charter that is considered to be a declaration of independence from neighboring kingdoms. After a series of battles fought in the 13th, 14th and 15th centuries, more cantons joined the confederacy and by the 16th century Switzerland was well-established as a separate state.
What Country was a well-established separate state by the 16th century?
The answer is the following: Switzerland


In 1838 the situation was slightly the same as in 1831. Muhammad Ali of Egypt was not happy about lack of his control and power in Syria, he resumed military actions. The Ottoman army lost to Egyptians at the Battle of Nezib on June 24, 1839. The Ottoman Empire was saved by Great Britain, Austria, Prussia and Russia by signing a convention in London in July 15, 1840 to grant Muhammad Ali and his descendants the right to inherit power in Egypt in exchange for removal of Egyptian military forces from Syria and Lebanon. Moreover, Muhammad Ali had to admit a formal dependence from the Ottoman sultan. After Muhammad Ali refused to obey the requirements of the London convention, the allied Anglo-Austrian fleet blocked the Delta, bombarded Beirut and captured Acre. Muhammad Ali accepted the conditions of the London convention in 1840.
In what year did the Battle of Nezib take place?
1839


Here is a question about this article: The tradition of presenting the trophy immediately after the game did not start until the 1882 final; after the first final in 1872 the trophy was not presented to the winners, Wanderers, until a reception held four weeks later in the Pall Mall Restaurant in London. Under the original rules, the trophy was to be permanently presented to any club which won the competition three times, although when inaugural winners Wanderers achieved this feat by the 1876 final, the rules were changed by FA Secretary CW Alcock (who was also captain of Wanderers in their first victory).
What is the answer to this question: when was the first trophy presented? 
****
So...
the trophy was not presented to the winners, Wanderers, until a reception held four weeks later
