Answer:
Difference between Representative Democracy
Explanation:
Representative Democracy is a government system, in which a representative group of people elected (chosen) by general public - are in power.
a) People elect small group in power, b) Those few <u>public elected</u> people directly exercise power, c) Government positions are open to many people, d) Anyone can run for office - whosoever chosen by public comes in power : are characteristics of representative democracy, not of oligarchy
Oligarchy is a type of government, in which a small group of powerful people (powerful due to wealth, education, religion, military link etc) - are in power & the power tends to stay with them.
Oligarchy is run by a small group of powerful people, <u>not elected</u> by general public. Only those few powerful people exercise direct or indirect power - as they are not public representatives. Government positions are not open to many people, anyone cant run office, as the power tends to stay accumulated in that powerful group's hands.

Answer:
d). It is easier to make a large reflecting telescope than a large refracting telescope.
f). A reflector can collect more light than a refractor.
Explanation:
A telescope is a device that is used to observe distant objects by the use of lenses and mirrors. It is also used to observe different distant objects by their reflection, absorption, emission or the reflection of the electromagnetic radiations.
Most of the professional telescopes are reflectors because :
1. The reflected telescope is able to receive more of the light when it reflects all the light falling on surface. And it is easier for making a large telescope rather then making large lenses for the refracting telescope. So it is easier to make large reflecting telescope than a large refracting telescope.
2. A reflected telescope receives all the wavelength of the light and it reflects all the light falling on the surfaces where it is refracted telescope that contains lenses cannot absorbs all the light and causes the chromatic aberration.
