Sentence Correction

Hi All,

In the below question of OG-10 Q96, the OA is "E". For kicking out "D", OG says " Choice D offers the necessary infinitives, but gerund phrase closing.... imprecisely refers to the act of closing rather then to the condition of the closed doors."

Can someone please help me decrypt what OG mean to say here ?

The National Transportation Safety Board has recommended the use of fail-safe mechanisms on airliner cargo door latches assuring the doors are properly closed before takeoff and to prevent them from popping open in flight.

(A) assuring the doors are properly closed
(B) for the assurance of proper closing
(C) assuring proper closure
(D) to assure closing the doors properly
(E) to assure that the doors are properly closed

The National Transportation Safety Board has recommended the use of fail-safe mechanisms on airliner cargo door latches assuring the doors are properly closed before takeoff and to prevent them from popping open in flight.

(A) assuring the doors are properly closed
(B) for the assurance of proper closing
(C) assuring proper closure
(D) to assure closing the doors properly
(E) to assure that the doors are properly closed

Intention of the original sentence is that mechanisms ensure that doors are properly closed (This doesn't mean that the mechanisms help in closing the doors, as depicted by choice D). Therefore E is preferable over D

" Choice D offers the necessary infinitives, but gerund phrase closing.... imprecisely refers to the act of closing rather then to the condition of the closed doors."

Here goes the decoding, sentence by sentence

Choice D offers the necessary infinitives - this says that the 'to+verb' form is constructed parallely; 'to assure.....and to prevent'

but gerund phrase closing.... imprecisely refers to the act of closing rather then to the condition of the closed doors. - option D wrongly says that the board will ensure someone will close the doors i.e., board is monitoring a PERSON. However, the board has to monitor a CONDITION of ensuring that the doors are closed but not a PERSON or ACTION.

Hope this helps.
