reading and reasoning skills, such a
vast undertaking requires a clear demonstration
of benefit before being undertaken.

(C) Before undertaking to improve the
reading and reasoning of almost all
citizens, it is necessary to show that
the project will work.

(D) Before the project of improving almost
all citizens’ reading and reasoning

be demonstrated.

(E) Prior to the improvement of citizens’
