Sentence Correction

OA - E

Pls help by answering my question above.

IMO C.

By the way, if the underlined portions are correct, choices A, D, and E would each contain two consecutive instances of "would".

the OA is E
option E correctly maintains parallelism with the use of 'that' and 'would' indicates future from a past action's perspective.
were established - past tense
would - future from past's perspective

jsl wrote:The federal rules aimed at protecting human subjects of medical experiments were established to ensure that patients must be warned of potential risks and an independent panel would evaluate the experiment before it was conducted.

A. must be warned of potential risks and an independent panel would
B. must be warned of potential risks and that an independent panel
C. are warned about potential risks and that an independent panel
D. will be warned about potential risks and an independent panel would
E. would be warned of potential risks and that an independent panel would[/img]

An quick and efficient approach:

In A and B, ensure and must create an error of redundancy. Eliminate A and B.

The correct idiom is warn of. Eliminate C and D.

The correct answer is E.

Thanks a lot.
I have duly added this point to my flashcards..

The following is correct:

The new rules were issued in order to ensure that all patients would be vaccinated.

The issue here is tense. That all patients would be vaccinated is an event happening in the past after another past event (the new rules were issued). The verb would is needed in order to make the sequence of events clear.

As mentioned above, Warned/Warn should be followed by "of" not "about". So, C is wrong.
