A, B and C have the same error

The development of a new type of manufacturing (...) will involve

The new type of manufacturing "will involve (...)", not its "developement" (logical error). We are down to D and E.

D. A newly developed type of manufacturing called 3-D printing, or additive manufacturing, involves futuristic printing machines that can replicate 3-D images, and this will lower costs considerably by greatly expanding who and where products can be made.

It seems to say that the fact that "can replicate 3-D images" will lower the cost: wrong.
"who (...)products can be made" is another error in the answer. "Who" needs a different verb than "where" ( where products can be made and who can make them )

E is correct

Yes, it is. "Greatly" is an adverb correctly describing the "expanding", which is a progressive form of verb here.

You can ask: How sh is expanding?
And you can answer: Sh is expanding greatly.

B vs E, although I agree with E as the correct answer choice I'm a bit dissapointed about the change in meaning from the original sentence. B says 'can' lower the costs while E says 'will' lower the costs. These two things are obviously different and thus creates confusion

Anyone wish to add something to this?

This is an excellent question! It is actually a subtle change that I didn't notice the first time that I read through these answers. Let's look at them:

B. The development of a new type of manufacturing – called 3-D printing or additive manufacturing – will involve futuristic printing machines that can replicate 3-D images and that can lower costs considerably by greatly expanding where products can be made and who can make them.

E. A newly developed type of manufacturing called 3-D printing, or additive manufacturing, involves futuristic printing machines that can replicate 3-D images and that will lower manufacturing costs considerably by expanding where products can be made and who can make them.

Honestly, I am a bit disappointed with this answer choice. You are correct that the meaning has been changed. In (B), we can see that this technology has the ability to lower costs and replicate 3-D images. In (D), the meaning is slightly different. The technology still has the ability to replicate 3-D images, but doesn't yet have the ability to lower costs. That will happen in the future.

Now maybe, in (B) this idea is implied with the use of "will involve," but I think this is a very very weak inference and likely not true.

Ultimately, I think this is a flaw in the question. Whoever wrote this questions probably didn't notice the change that they were making to the sentence in (E). I don't see any reason for the change in meaning, unless the question writer expects us to have outside knowledge about 3-D manufacturing. I know that it is pretty expensive at this point, and it is not good for a lot of uses because it is so expensive. But the GMAT would never require us to have this kind of knowledge to choose a correct answer.

I think the safest thing to say here is that the answer choice is slightly flawed. The question writer made a mistake that alters the meaning of the sentence. The best wording of answer choice (E), and to make this question truly beneficial for GMAT prep is as follows:

A newly developed type of manufacturing called 3-D printing, or additive manufacturing, involves futuristic printing machines that can replicate 3-D images and that can lower manufacturing costs considerably by expanding where products can be made and who can make them.

I hope that helps!

Whats wrong with B anyways..I mean if the author had not committed the mistake of us having pre knowledge on 3D printng..ie Had there been a can in E too

Zarrolou hints at why (B) is wrong. The problem here is the subject of the sentence. Instead of "type of manufacturing" as the subject, answer choice (B) makes "development" the subject of the sentence. Now this may not make sense immediately, but ask yourself if development is the logical subject of the verb:

"development ... will involve futuristic printing machines ..."

This is illogical! The development won't involve these things. This is a description of 3-D printing and printers—not a description of their development. So this is a subtle distinction but an important one.

"... the new type of manufacturing ... will involve ... printing machines ..."

Does that make sense?

We can't describe the development of 3-D printers in the same way that we describe 3-D printers.

Cheers!

Is there anyway we can identify such errors...This is my second same mistake today...and I dont seem to get a hold of it...It passes the ear test so smoothly that it is never a suspect

These errors are tough to notice because they are so subtle. And it's even harder when they separate the subject and the predicate, like in this sentence. Our minds are really good at ignoring this sort of illogical sentence and making sense of what is there, so we have to pay attention to the meeting created by the words in the sentence—not what our minds tell us.

This isn't the best answer, I know, but there is no hard fast rule. We have to pay attention to the logical coherence of the subject and the predicate. Do they make sense together? I suppose the word "development" might be a good tip, though. It is real easy to start talking about the thing itself even though the subject is "development." So I'd keep an eye out for that. Besides that make sure the sentence is logical.

Do "new type of manufacturing " and "newly developed type of manufacturing " mean the same ?
newly developed manufacturing process should be the correct clause , I think "newly developed type of manufacturing " conveys meaning like
"moulding type manufacturing " or rolling type manufacturing.

Moreover , while spotting differences between B and E , there seems to be another subtle meaning change.

B : The development ... will involve
E : A newly developed... involves

Doesn't this imply a meaning change ?

Choices A, B, C have the error of using future tense (will)
Choice D, use of "who and where" does not make sense

Choice E is the correct Answer

It is not the "development of......." that will involve futuristic printing but a type of manufacturing will involve futuristic printing.....so A, B and C are eliminated.

D breaks the parallel construction of "that"
E - the best answer choice as it says- a Type of manufacturing involves futuristic printing that can.....and that will......

Hope it helps!

Can you please let me know if E is not changing the tense of the original sentence?

The original sentence seems to be in future tense (suggesting that the technology will develop in future), while E seems to suggest as if the technology has already been developed.

In the original sentence - Development .. will involve - This is not correct. As development (in itself) will not involve.

The intent of the sentence is to highlight what 3-D printing consists of in terms of machines and what are the machines capable of .. (in future)..

Eliminated A,B,C purely because of the way the first clause is constructed.

Then, it was easy to pick E over D.

we have a new type of manufacturing.
this new type will involve futuristic printing machines.
these machines can replicate 3d images and can lower costs.

A. The development of a new type of manufacturing – called 3-D printing or additive manufacturing – will involve futuristic printing machines that can replicate 3-D images and that can lower costs considerably by greatly expanding who and where products can be made.
it is the new type of manufacturing that will involve printing machines that can do 2 things, and not the development of the new type of manufacturing.

B. The development of a new type of manufacturing – called 3-D printing or additive manufacturing – will involve futuristic printing machines that can replicate 3-D images and that can lower costs considerably by greatly expanding where products can be made and who can make them.
same error as in A.

C. The development of a new type of manufacturing, which is called 3-D printing or additive manufacturing, will involve futuristic printing machines that can replicate 3-D images and that can lower costs considerably by greatly expanding where products can be made and who can make them.
same error as in A and B.

D. A newly developed type of manufacturing called 3-D printing, or additive manufacturing, involves futuristic printing machines that can replicate 3-D images, and this will lower costs considerably by greatly expanding who and where products can be made.
pronoun "this" refers to an action. since it does not have a clear noun-antecedent, D is incorrect.

E. A newly developed type of manufacturing called 3-D printing, or additive manufacturing, involves futuristic printing machines that can replicate 3-D images and that will lower manufacturing costs considerably by expanding where products can be made and who can make them.
we are left with E, although I don't like it.
