Official Explanation

(A) This choice says that Gawande argues that doctors could use … checklists … and greatly reduce … errors, implying that the two actions are unrelated. In fact, using the checklists would lead to the reduction in errors; the sentence ought to say that doctors could use … checklists … to greatly reduce … errors. In addition, the placement of the modifier in his book is ambiguous. Logically, it ought to describe what Gawande argues throughout the book, but the placement seems to modify Gawande himself.

(B) CORRECT. By moving the verb argues closer to the subject (Atul Gawande), this sentence clarifies any ambiguity. The modifier in his book now properly describes the argument Gawande put forth in The Checklist Manifesto. Doctors could use … checklists … to greatly reduce medical errors correctly conveys that doctors’ use of checklists will lead to the reduction in medical errors.

(C) In this sentence, the modifiers greatly reducing the number of medical errors and saving both money and lives both modify doctors could use, and thus should be connected by and rather than with a comma.

(D) The parallel structure both X and Y requires the X and Y elements to be parallel. Saving money is not parallel to lives; saving should be before the word both (saving both money and lives) or it should be repeated after the word and (both saving money and saving lives).

(E) The same sort of checklists that pilots use to greatly reduce the number of medical errors sounds as though the pilots use their checklists to reduce medical errors.

hello experts egmat, Veritas prep, bb
can u plzz guide what is the structure of right answer . B checklist Manifesto,that doctors .... that is referring to what . i am always confuse when see that after coma (,) . how to relate it with sentence .
thanks

that is the extension of the statement Atul Gawande argues in his book that. Rest parts are noun modifiers.


I hope it helps.

Please give kudos if you like the explanation.

Atul Gawande, the former surgeon general, in his book, The Checklist Manifesto, argues that doctors could use the same sort of checklists as pilots and greatly reduce the number of medical errors, saving both money and lives.


A) Atul Gawande, the former surgeon general, in his book, The Checklist Manifesto, argues that doctors could use the same sort of checklists as pilots and greatly reduce the number of medical errors, saving both- usage of AND changes the meaning(use of checklists and reduce the number of medical errors are related actions)

B) Atul Gawande, the former surgeon general, argues in his book, The Checklist Manifesto, that doctors could use the same sort of checklists that pilots do to greatly reduce the number of medical errors, saving both

C) Former surgeon general Atul Gawande argues in his book, The Checklist Manifesto, that doctors could use the same sort of checklists as pilots, greatly reducing the number of medical errors, saving - Verb-ing modifiers reducing and savings are not connected properly using AND

D) Former surgeon general Atul Gawande argues in his book, The Checklist Manifesto, that doctors could use the same sort of checklists that pilots do to greatly reduce the number of medical errors, both saving - parallelism issue - both saving money and lives

E) In his book, The Checklist Manifesto, former surgeon general Atul Gawande argues that doctors could use the same sort of checklists that pilots use to greatly reduce the number of medical errors, saving


1. I narrowed to options B and E and ended up choosing E.

2. In option A and C, "that doctors could use the same sort of checklists as pilots" -- can we eliminate these options based incorrect usages of AS. (As followed by a noun is used for a role.)
Or is this ellipsis ? "that doctors could use the same sort of checklists as pilots (do)"

I think B and E convey the same meaning.

Can someone please help explain what is the difference in meaning between B and E? Thanks.

Super tricky one here.... I think this is an issue related to how helping verbs, such as DO, can sub in for lengthier verb phrases. In B, the use of DO repeats the entire verb phrase about the usage of some kind of checklist. The DO emphasises the concept of using a checklist but not the same copy of the checklist...."in the same way that pilots do (also use) [some sort of checklist]". In E, however, the lack of DO makes it sound like Gawande is arguing that doctors should "use checklists (in the same way) pilots use (checklists)" to reduce medical errors...which - echoing the OE - is illogical.

I chose B,

Eliminated E because :-In his book cant refer to The Checklist Manifesto, it should be Atul Gawande,

Plus B makes more sense.
