The main reason for migration is mostly food: people migrate where they can produce food easily, catch it, or in modern times, to produce money to buy food.

Finally, people might also migrate to look for a better climate (where they don't have to built very cold resistible houses for example).
I think the answer is they were competing for land and gold, but I am not 100% sure.
Particles zipping through space could be the wrong stuff for Mars astronauts, best supports the answer to Part A. Hence option (A) is the answer.
<h3>Write a short note on 'Trip to Mars could damage astronauts’ brains'.</h3>
'Trip to Mars could harm astronauts' brains', according to Charles Limoli, who also wrote the study in which scientists exposed mice to high-energy charged particles. It was intended to mimic cosmic rays in outer space. The mice displayed memory issues six weeks later. The author of the study is now concerned that astronauts may experience comparable effects on prolonged missions outside of the ozone-shielding atmosphere of Earth.
Mars exploration is one illustration. Traveling to Mars would be risky if astronauts experienced the same side effects as these mice. Cosmic rays are produced by the explosion of large stars. Electrically charged particles make up this energetic radiation. This radiation would bombard a spacecraft and its astronauts as it moved through space at almost the speed of light.
