Problem: Matter should not be confused with mass, as the two are not quite the same in modern physics. For example, mass is a conserved quantity, which means that its value is unchanging through time, within closed systems. However, matter is not conserved in such systems, although this is not obvious in ordinary conditions on Earth, where matter is approximately conserved. Still, special relativity shows that matter may disappear by conversion into energy, even inside closed systems, and it can also be created from energy, within such systems. However, because mass (like energy) can neither be created nor destroyed, the quantity of mass and the quantity of energy remain the same during a transformation of matter (which represents a certain amount of energy) into non-material (i.e., non-matter) energy. This is also true in the reverse transformation of energy into matter.
What similar term is often used interchangeably with matter, although the two differ slightly in modern physics?
The answer is the following: mass

Problem: In October 2004, Sarah Forsyth claimed that she had been dismissed unfairly by Eton College and had been bullied by senior staff. She also claimed she was instructed to do some of Prince Harry's coursework to enable him to pass AS Art.

An employment tribunal in July 2005 found that she had been unfairly dismissed and criticised Burke for bullying her and for repeatedly changing his story. It also criticised the school for failing to produce its capability procedures and criticised the Head Master for not reviewing the case independently.
Who was criticized for not handling the Forsyth case independently?
The answer is the following: the Head Master

Problem: The victorious great powers also gained an acknowledgement of their status through permanent seats at the League of Nations Council, where they acted as a type of executive body directing the Assembly of the League. However, the Council began with only four permanent membersthe United Kingdom, France, Italy, and Japanbecause the United States, meant to be the fifth permanent member, left because the US Senate voted on 19 March 1920 against the ratification of the Treaty of Versailles, thus preventing American participation in the League.
Why was United Stated excluded from League of Nations Council?
The answer is the following: against the ratification of the Treaty of Versailles, thus preventing American participation in the League

Problem: Schools called "technical institute" or "technical school" that were formed in the early 20th century provided further education between high school and University or Polytechnic. Most technical institutes have been merged into regional colleges and some have been designated university colleges if they are associated with a local university.
If a technical institute is affiliated with a local university, what does its designation become?
The answer is the following:
university colleges
