We cannot simply assume that the lexicographers are wrong, and that they will not make arbitrary changes to the use of vocabulary. They must have been carefully studied and considered. However, lexicographers cannot ignore a basic fact and the basic requirements derived from it. : Languages and words are commonly used by the broad masses of the people, and they have an extremely extensive social nature. Therefore, the standardization of languages and words cannot be carried out in the ivory tower, but must follow the mass line. What do you mean by "basic requirements" in this passage? ['Dictionary compilers cannot change the vocabulary.', 'Dictionary compilers should be familiar with the specific process of dictionary compilation.', 'The standardization of language should serve the general public.', 'The standardization of language should be decided by the general public.']
