Explanation

The question tests your knowledge of subject-verb agreement. ‘pattern of changes’ is singular and not plural, hence it requires ‘indicates’ and not ‘indicate’. So options (1), (2) and (3) are ruled out. Between (4) and (5), proper usage is 'descendent of' and not 'descended from'. Hence (4).
