Answer:
B) X rays do not penetrate Earth's atmosphere
Explanation:
The Chandra X-Ray observatory should operate in space due to the nature of the radiation it is using. X-rays are high energy electromagnetic radiations. The observatory will not be able to function properly since it uses x-ray because, the rays cannot penetrate the earth's atmosphere. A radiation of this type would easily be cut off by the particles in the atmosphere. The observatory has to be positioned outside of the earth.
French Indochina was made up of Vietnam (which was split into two parts: Tonkin and Annam), Cambodia and Laos (Laos was added later than the rest, in 1893).
Korea was never part of French Indochina, which also can be explained by the fact that it does not directly share a land border with the rest.
