Explanation:

• The past perfect progressive tense denotes  a continuous action which was finished  at given time in the past. The tense conveys that an action which began in the past continued up to another time in the past
• The past perfect progress is also know as the past perfect continuous  and is a verb tense which denotes something which started in the past, continued in the past, and completed at a defined/stated point in the past.
• This tense is formed with the modal had+been+present participle-ing, examples, : I had been studying in the library all morning,  Nivedha had been painting her house for weeks, however she finally gave up.
