What this question is testing
Objective: Grammar: passive voice
Prompt focus: Choose the correct passive form. The ancient manuscript ____ in a sealed vault for over a century.
Why the correct answer works
has been kept
Has been kept is the present perfect passive, correct because the manuscript receives the action.
Why the tempting wrong answer fails
Incorrect. Has kept is active and would mean the manuscript did the keeping.
