Answer:
(C) ocean floor
Explanation:
The protolith or parent rocks that forms schists are basically mudstones and shales. These are clastic sedimentary rocks that are rich in fines(clay sized particles).
Most shales are usually formed in deep ocean floors because larger sized clastic sediments cannot reach these environments. Winds and waves acts as active agents to deposit fines on the ocean floor.
Since shales are predominantly made up of clay minerals which are products of micas that have been chemically altered, we expect these clay minerals which are hydrous(contains water) to revert back to mica under metamorphic conditions.
As metamorphic transformation progresses under intense pressure and temperature and also minerological transformation, our rock moves from slate, to phllylite and then to schists.
Slate is a low grade metamorphic rock that is usually fine grained and foliated. As metamorphism increases, mica begins to grow and a shiny lustre appears in the rock, a phyllite results. Schists have larger mica grains and are foliated also.
Desert dunes are mostly made of sandstones. Their metamorphic transformation yields quartzite.
Coral reefs ar made up of rich calcite deposits and would form a metamorphic rock known as marble.

Answer:
A scale tipping heavily in one direction symbolizes perfectly the effect of many international cultures becoming westernized.
Explanation:
A is not correct because that can symbolize a tense situation where things are on the verge of escalating.
B is correct because this represents well as to how much the Western culture is increasing its influence, while the other cultures are gradually dying out.
C is not correct because this would symbolize the exchange of goods, technology, knowledge, for mutual benefit.
D is not correct because this would symbolize dependence.
The correct answer is - B. It became a democracy in the 1980s.
The country of Nepal officially became a democracy in the 1980's, and is still a country that proclaims itself as a democracy. Now we have to take into consideration that when a country proclaims itself like something it doesn't have to mean that it is true. So in Nepal we have a situation where officially there is democracy for around 4 decades, but the reality is that all of the governments have been practicing totalitarian regimes, people have been forced to do things that they don't like, the media is controlled by the government.
