Answer:
what year for this question?
Enrich fermi was a scientist and a physicist .He discovered nuclear fission and he led several tests releated to the use of nuclear power and his work was mostly on induced radioactivity by neutron bombardment and the discovery of transuranic elements or a nuclear reactor .His new find followed Marie Curies and Joliot’s discovery of artificial radioactivity .At age 14 he lost his brother from a minor throat surgery accident.In order to escape the pain of losing his brother ,Fermi buried himself in books about physics that fascinated him and soon got him into college with an entrance exam essay that was judged worthy of a doctorates degree .So you could say that his own loss of his brother motivated him to start making discoveries of his own in physics and on experimenting with neutrons. Hope this helped !
Because as you can see the options: California, New York, Florida and Texas are big states and are overpopulated that's probably why a candidate spend a lot of time and money campaigning there.
I hope this helps!
