Answer:
Had
began
Explanation:
'Had' is past tense and describes an action that happened at a time earlier than the present time.
Example: I had lost my $20 that my mom sent me to the store with to buy bread, so when I got home, my mom was angry at me.
And again, 'began' is a simple past tense verb while 'begin' is present tense.
Example: I began studying my vocabulary last night, which resulted in me passing my pop quiz today.
