Answer:
Kilimanjaro
Explanation:
The name of Africa's tallest peak (19,341 feet above sea level) comes from two local languages: Swahili and Chagga. When combined, the words translate to "Shining Mountain" or "White Mountain." Alternate names given to Kilimanjaro throughout history translate to "Mountain Where Birds Cannot Fly" and "Mountain of Silver Moons." The Chagga people believe that a spirit lives atop the peak and will cause sickness to some who climb. Anthropologists think this is likely their method for explaining altitude sickness, caused by attempting to climb Kilimanjaro too quickly.

Answer:
A particle or packet of light.
Explanation:
A photon essentially doesn't have a charge and thus can't be called an electron. So, option 1 is incorrect.
Photons are in fact packets of electromagnetic energy that light is made up of. So, option 2 is correct.
A photon is not a gaseous mass that indicates the preliminary stage in a star's growth and thus can't be a protostar. So, option 3 is incorrect.
Photons having different energies are constituents of the electromagnetic spectrum and thus a single photon can't be a spectrum. So, option 4 is incorrect.
