Hi,
diff between simple past and past perfect at specific time in past.
For e.g.-She never saw a bear before she moved to Alaska. why Not Correct This is correct.
She had never seen a bear before she moved to Alaska. Why Correct This is also correct.

The Simple Past is commonly, but not always, used instead of the Past Perfect when a word like 'before' makes the sequence clear.

Compare these example where there is no such sequencing word.
Tom came home at 6 pm. Mary cooked dinner. She cooked it after 6pm.
Tom came home at 6 pm. Mary had cooked dinner. She cooked it before 6 pm.
