单项选择题

Albert Einstein once attributed (把......归因于) the creativity of a famous scientist to the fact that he "never went to school, and therefore kept the rare gift of thinking freely". There is undoubtedly a truth in Einstein’s observation; many artists and geniuses seem to view their schooling as a disadvantage. But such a truth is not a criticism of schools.
