Changes in language elements are sometimes not waiting for changes in social life-that is, even if social life has not changed significantly, vocabulary, pronunciation and grammar may change quietly, and the changes in vocabulary are relatively obvious. The point directly supported by this passage is:. ['Changes in language elements are not completely dominated by social life.', 'The development and change of language elements are often present.', 'When social life develops and changes, changes in language elements are more obvious.', 'Generally speaking, changes in vocabulary are more pronounced than changes in speech.']
