In the mid 1920's the Hawthorne Works of the Western Electric Company was the scene of an intensive series of experiments that would investigate changes in working conditions as to their effects on workers' performance.

A) same
B) investigating the effects that changes in working conditions would have on workers' performance
c) that investigated changes in working conditions' effects on worker's performance.

Answer is B
IMO the answer should be c

please explain. I feel that c flows better

c) that investigated changes in working conditions' effects on worker's performance.
Unidiomatic and redundant.

please look again at the bold part.

Hope this helps

"that" is ambigous It usually refers to the immediately preceding noun which would be expirements. Did the experiments investigate something? NO

IMO Investigating would be a present participle modifying Western Electric Company hence B

Somone feel free to correct me or add.

Regards,
CR

it is logic to say "investing effects" not "investigating changes"

so C, A, is out
