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:
<em>Many of the products I use are from Asia's resources, especially food.
</em>
<em>
TWO EXAMPLES: rice (comes from Thailand) and fish sauce (aka "nouc mam") that comes from Vietnam.
</em>
<em>The utilization of Asia’s natural resources has depended, to a large extent, not only on the development of technology but also on political circumstances. Thus, until the end of World War II and the beginning of the process of decolonization in Asia, most Asian countries were not free to develop their own natural resources independently and without reference to the economic interest of a colonial power. Cultural attitudes also have affected the utilization of resources. In India cultural taboos prohibit the slaughter of cattle either for food or to conserve resources when the animals are no longer productive.</em>
