What is the main idea of the passage?

Câu hỏi: Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 35 to 42.
Albert Einstein, a German born in March, 1879, is probably the most famous physicist in history. Einstein became interested in physics at an early age. When he was 5 years old, his father showed him a compass. Even at that young age, Einstein comprehended that something in space was making the needle move. From this early interest, Einstein would grow to become the physicist that formulated the special and general theories of relativity. He also contributed to the quantum theory and statistical mechanics. He received the Nobel Prize in Physics for his explanation of the photoelectric effect and for his contributions to Theoretical Physics. However, it was his Theory of Relativity that made Einstein a household name and people associated Einstein with the word "genius".
When Einstein saw that Newtonian mechanics was insufficient, he first began his scientific work. It could not make the laws of mechanics agree with the laws of the electromagnetic field. Einstein theorized that a theory of relativity must take the theory of gravitation into consideration. So Newton's law of gravity was not completely accurate. Einstein's equation E = mc2​ replaced Newton's law of gravity. Einstein's theory was believed correct because it took electromagnetic phenomena into consideration. It also made allowance for a characteristic of gravitation specifically in that it curves over space and time. This meant that matter such as a planet or a star could make space and time curve in response to the matter that existed. This theory was important because it took into consideration the fact that the universe is constantly changing and expanding
Einstein's works formed an important part of the foundation of modern physics, and brought great fame to Einstein. But they were completed without conferring with his scientific colleagues and with very little reference to existing scientific reading materials. For this reason, many scientists were resentful of him. However, Einstein truly deserved fame.
