I'll go with (D)

(A) - that would investigate changes in working conditions as to their effects on workersâ€™ performance -

(B) - investigating the effects that changes in working conditions would have on workersâ€™ performance - changes modifies effects: wrong

(C) - for investigating what are the effects in workersâ€™ performance that changes in working conditions would cause

(E) - to investigate what the effects changes in working conditions would have on workersâ€™ performance - effects changes in working conditions: wrong

should be B.

The corrected part is a modifier, and B is the only correct usage with the participle INVESTIGATING

(B) uses "effects that changes in.. ": it should be "effect that changes in.." or "effects that change in.. " - subject and verb not in agreement here.

I disagree with you Mav.

Change here is not the verb of the subject effect.

changes is the subject since its the changes that would have EFFECTS(more than one effect).

Effect is not a subject here and should not be aligned with changes

You're right, here Tareks! I misread - thanks for pointing that out.

Moreover, (D) conveys that the experiments investigated changes in working conditions whereas (B) conveys that the experiments investigated the effects of changes in working conditions.

B is better than D

(A) that would investigate changes in working conditions as to their effects on workersâ€™ performance
would is wrong

(B) investigating the effects that changes in working conditions would have on workersâ€™ performance
investigating implies it is still going on, wrong

(C) for investigating what are the effects in workersâ€™ performance that changes in working conditions would cause
"are" is in the wrong place

(D) that investigated changes in working conditionsâ€™ effects on workersâ€™ performance
Correct

(E) to investigate what the effects changes in working conditions would have on workersâ€™ performance
wordy and unclear, needs "that" after effects

Investigating DOEST NOT imply that its still going on.

The detectives just came back from the crime scene they were investigating.

But note you have "were" there. It would be wrong if you say "The detectives just came back, investigating the crime scene."

Hmmm you may be right. (B) still doesn't read good to me. The role of "changes" in the sentence is confusing, for it can serve as a verb or a noun.

(B)
"investigating... " (present participle) correctly modifies the noun experiments.

(A) their.. ambiguous antecedent
(C) "for" requires noun.
(D) "Experiments that investigated the changes in working conditions' effect on worker's performance.

Here, we are talking about effect that changes would have... not changes on workers performance.

Actually, (D) changes meaning.

(E).. I did not find any error. but when compared to (B), it is wordier.

Correct me if I am wrong?

I will go with 'B', as JPV pointed 'D' changes the intent of the original sentence.

Ok, I agree that "changes in working conditionsâ€™ effects" is unclear. It sounds like it was the effect of the condition and it was the change in the effects ...

(B) is better.
