Here is a question about this article: 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 is the answer to this question: What similar term is often used interchangeably with matter, although the two differ slightly in modern physics?
****
So... mass

Here is a question about this article: Fiame Mata'afa Faumuina Mulinu'u II, one of the four highest-ranking paramount chiefs in the country, became Samoa's first Prime Minister. Two other paramount chiefs at the time of independence were appointed joint heads of state for life. Tupua Tamasese Mea'ole died in 1963, leaving Malietoa Tanumafili II sole head of state until his death on 11 May 2007, upon which Samoa changed from a constitutional monarchy to a parliamentary republic de facto. The next Head of State, Tuiatua Tupua Tamasese Efi, was elected by the legislature on 17 June 2007 for a fixed five-year term, and was re-elected unopposed in July 2012.
What is the answer to this question: What office was held by Fiame Mata'afa Faumuina Mulinu'u II?

So...
Prime Minister
