Should'nt it be simple past tense in OA because of the time marker " before" ?
One purpose of the past perfect (
had + VERBed) is to indicate that an event in the more recent past is LINKED to an action further in the past (the past perfect action).
Before John became a painter, he studied music.
Here, the usage of the simple past tense for both actions conveys the following sequence:
First John studied music.
Later he became a painter.
There is no indication that the event in the more recent past (
became a painter) is linked to the action further in the past (
studied music).
Before John became a painter, he HAD STUDIED music.
Here, the usage of
had studied (past perfect) implies the following:
When John became a painter, he STOPPED studying music.
The purpose of the past perfect is to indicate that the event in the more recent past (
became a painter) is LINKED to the action further in the past (
had studied music).
OA to the SC above:
The personal income tax did not become permanent in the United States until the First World War; before that time the federal government had depended on tariffs as its main source of revenue.
Here, the usage of
had depended (past perfect) implies that the event in the more recent past (
the First World War) is LINKED to an action further in the past (
had depended on tariffs).
Implication:
When the First World War occurred, the federal government STOPPED depending on tariffs.
