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.

Answer:
The two rock can be confused with each other as both appear rough to touch and both are found in shades of black & brown and dark themes, also shades of grey sometimes prevail.
They differ in the mode of formation as Quartzite is Metamorphic Rock while Basalt is the Igneous rock formed from the Volcanoes
Explanation:
The two rock can be confused with each other as both appear rough to touch and both are found in shades of black & brown and dark themes, also shades of grey sometimes prevail. They do have similarities in the hardness on some scale as Quartzite is hard while basalt is intermediate in hardness.
Major difference between them are:
They differ in the mode of formation as Quartzite is Metamorphic Rock while Basalt is the Igneous rock formed from the Volcanoes. Quartzite have medium grain size and foliated, granular structure while Basalt is fine grained and glassy in texture.
