setting free the more than 500 slaves who were legally considered his property.
(A)
setting free the more than 500 slaves who were legally considered(B) setting
free more than the 500 slaves legally considered as
Use of "the" doesn't make sense. We want to talk about a number, not a particular of group of 500 slaves.
(C) and set free more than 500 slaves
, who were legally
considered as"Robert Carter III stunned"
"Robert Carter III set free"
The parallelism is fine
The usage of the comma makes the clause following 500 slaves non restrictive.
The use of "as" is not correct
(D) and set free more than
the 500 slaves who were legally considered
"Robert Carter III stunned"
"Robert Carter III set free"
The parallelism is fine
Use of "the" doesn't make sense. We want to talk about a number, not a particular of group of 500 slaves.
(E) and
he set free the more than 500 slaves who were legally
considered as"Robert Carter III stunned"
"Robert Carter III he set free"
Parallelism is incorrect.
The use of "as" is not correct
