<span>The answer is letter A.
Ice Age or glacial period refers to the extended period of well-below-average temperatures. It is a prolonged period where reduction in the temperature of the Earth’s surface and atmosphere are caused by the expansion of continental and polar ice sheets and alpine glaciers. Usually this phenomenon occurs in the northern and southern hemispheres where extensive ice sheets are seen most.
<span>At present we are now experiencing an interglacial period after the Holocene Ice age.</span>

Answer:
B Germany
Explanation:
This is because of the world war.
Answer:
equivalence
Explanation:
Recall that this principle is the basis of Albert Einstein's theory of general relativity. According to the German researcher, gravity is not a force that acts independently on each object, but rather a deformation of the same temporal space tissue.
According to the test carried out now by the team of astronomers, these three dead stars in two of their forms, a pulsar or a white dwarf, are perfect candidates to confirm the theory.
The equivalence was already understood centuries ago by Galileo Galilei. In his famous test of the spheres in the Tower of Pisa he demonstrated the existence on Earth. Subsequently, astronaut David Scott did the same on the lunar surface in 1971.
Now, this team has demonstrated it by studying two of the densest objects in the universe. Until today, many believed that the high density of the pulsar made him exempt from complying with the equivalence principle. However, being subjected to the gravitational field of one of the white dwarfs, the closest and least massive, after six years of observations, they have been able to demonstrate that both bodies have the same acceleration. And, if there is a difference, it is less than three parts between one million. That is the conclusion reached by a new test that tested Einstein and corroborated his theories once again.
