I've found the following sentence on a question of book.
By 2007, UK household wealth ____ (rise) from 4,500 billion to just under 7000 billion.
The correct answer of the question is "had risen".
By 2007, UK household wealth had risen from 4,500 billion to just under 7000 billion.
But my answer was "rose"
By 2007, UK household wealth rose from 4,500 billion to just under 7000 billion.
I still can't find what are the grammar points related to this correct answer. I speculated this answer because there is the year mentioned in the question. Whenever the time is mentioned the better tense is the past simple rather than past perfect, isn't it?
Please someone tell me what the reason for the above correct answer and why one answer is not correct?
dileepa I still can't find what are the grammar points related to this correct answer. 'By 2007' marks a past time occurring after the past perfect time of 'had risen'.
