What is the main contrast between Einstein's childhood image and later fame?

Correct answer: In childhood he was seen as ordinary or different but later became a great scientist

The governing idea is the contrast between an early public impression and a person’s later achievement. Einstein’s childhood was not presented as the beginning of an obviously celebrated career. His unusual behaviour, delayed speech, dislike of rigid learning, and independent questions made some people regard him as different or less capable. However, he later became one of the most influential scientists in history. Option A correctly expresses this transformation from being misunderstood or seen as ordinary to gaining worldwide fame for scientific work. The other options invent occupations and social positions that do not belong to his biography, so they cannot explain the contrast described in the lesson.
