The quality of the new products that ACME Corporation have developed

I think E!
Products have been developed and that they have arrived on shelves, but it is quality that worries analysts.

What's wrong?

ACME Corporation has developed products

(not products have developed)
_________________

I would have gone for D only .. The same logic ' ACME Corporation has developed products '

“The quality of products” is singular and hence the verb should be ‘worries”; “the Acme Corporation” is singular and hence the verb should be “has”; this is confirmed by the mention of ‘has lost’ in non-underlined part of the passage. Only D subscribes to this format.
_________________

The subject of "have developed" is the ACME Corporation (singular), the subject of "have arrived" is new products (plural) and the subject of "worry" is the quality (singular). Keeping this in mind:

(A) The quality of the new products that ACME Corporation have developed over the past year and that have recently arrived on retailers’ shelves worry - Incorrect. Should be has developed and worries.
(B) The quality of the new products that ACME Corporation has developed over the past year and that has recently arrived on retailers’ shelves worry - Incorrect. Should be have arrived and worries.
(C) The quality of the new products that ACME Corporation have developed over the past year and that has recently arrived on retailers’ shelves worry - Same as Option A
(D) The quality of the new products that ACME Corporation has developed over the past year and that have recently arrived on retailers’ shelves worries - Correct!
(E) The quality of the new products that ACME Corporation have developed over the past year and that have recently arrived on retailers’ shelves worries - Incorrect. Should be "has developed"

Hope this helps

For the subject 'ACME Corporation' , verb should be 'has' , For the subject 'products' , verb should be ' have'
For subject 'The quality of the new products', verb should be 'worries'

so D

Here the quality of the new products is the subject so should not there be "has" in "that have recently arrived on retailers' shelves". How can you say this being talked about products and not quality (singular). If I re-write this sentence by omitting the ACME corporation part, it will look like

The quality of the new products that has recently arrived on retailers' shelves worries.....


This makes more sense, here 'worries' verb confirms to the subject quality and "has" also confirms to the subject quality.

While "that have recently arrived on retailers' shelves worries" in same clause we are reffering have to products and then worries to quality?

Please let know what am I missing.

see this logically. "that have recently arrived on retailers’ shelves" - what have recently arrived? products or quality?
only 'products' make sense. that's why the subject is 'products' and verb should be 'have' and not 'has'.

Sub-verb.
QUALITY(Singular) Will carry the verb HAS, so we left with B and D.

The Products.. (Plural)........... So have
Left with only D

This question is a classic example of the agreement (between subject and verb) error family. Note the telltale signs:

• A 3-2 split between the singular and plural forms of the same verb (“worry” in A/B/C vs. “worries” in D/E)

• Prepositional phrases to fill the sentence with several nouns, obscuring the true subject of the sentence

With agreement questions, once you have noticed one (or both) of these signals, your job becomes to identify the subject of the verb in question. Two strategies will help you in that pursuit: slash and burn (get rid of all unnecessary sentence elements) and logic. The most obvious Decision Point on the problem above is “worry” vs. “worries”; decide using slash and burn (and logic) what the subject is. By getting rid of all the modifiers, it is clear that “quality” is the subject for that verb and it makes sense (quality can logically worry), so answer choices A, B, and C are wrong. In your choice between answer choices D and E, there is only one Decision Point: “has developed” vs. “have developed.” Since the corporation is the subject (logically and grammatically) for that verb, it must be the singular “has developed.” Answer choice D is correct.

The quality of the new products that ACME Corporation have developed over the past year and that have recently arrived on retailers’ shelves worry many business analysts, who think that the company has lost focus under the new CEO’s leadership.

(A) The quality of the new products that ACME Corporation have developed over the past year and that have recently arrived on retailers’ shelves worry
(B) The quality of the new products that ACME Corporation has developed over the past year and that has recently arrived on retailers’ shelves worry
(C) The quality of the new products that ACME Corporation have developed over the past year and that has recently arrived on retailers’ shelves worry
(D) The quality of the new products that ACME Corporation has developed over the past year and that have recently arrived on retailers’ shelves worries
(E) The quality of the new products that ACME Corporation have developed over the past year and that have recently arrived on retailers’ shelves worries

The sentence has a subject verb agreement issue as the subject is the ACME and the verb that refer to the subject is have developed but ACME Corporation is singular and have is used to refer plural entity therefore the correct use should be ACME corporation:has developed.

The second have is referring to the products which is correct. The correct Answer is D

Easy question. My steps:

1) Find subject (quality). Singular
2) Skip prepositional phrase
3) Find a verb (worries). We have two choices left
4) Compare (D) and (E). ACME Corporation (singular), then - Has

Hi GMATNinja,

I was wondering could you please explain why option D is correct? I eliminated option D because we are using "that" to refer back to two different entities (quality and products). In turn, we are using two different verbs: has & have. I thought a pronoun cannot refer back to two different entities unless I am incorrect?

Could you please shed some light on this as I have yet to come across an official question that has used a a pronoun to refer back to two different entities.

Thank You!

first has vs have ; correct will be has since Acme corporation is singular; negate A,C,E
b/w B & D
The quality of the new products that ACME Corporation has developed over the past year and that have recently arrived on retailers’ shelves worries

has developed refers to the quality singular ; and that have refers to products ; plural
IMOD

Responding to tags on a duplicate topic.
globaldesi and JS1290 , this option D is different from the option D about which you asked.

This (D) contains products, plural.

That does not modify quality.
• That modifies products. That immediately follows products. True, "that" can "reach back" over the prepositional phrase, but . . .
• logically, that cannot modify quality. Quality has not recently arrived on retailers shelves.

[That] have arrived refers to products.

We have two that-clauses, both of which are "surrounded" by the subject and verb of the main clause.
The verb for quality is worries.
The [poor] quality of XYZs worries business analysts. (Business analysts worry about the quality of XYZs.)

Let's shorten and strip the sentence.
(D) The quality of the new products that ACME Corporation has developed over the past year and that have recently arrived on retailers’ shelves worries many business analysts.

The sentence, stripped:
The quality of the new {products} that [ACME] [has developed] and that {have recently arrived} worries many business analysts.

In between the main subject and main verb in green are two that-clauses.
That-clauses have their own subjects and verbs, marked in blue.
Find the subject and verb for each THAT clause. Those verbs are "used up."
Try to read logically.
Which one makes more sense: Is ACME Corp developing quality? Or products?
Which one makes more sense: WHAT has arrived recently on retail shelves? Quality? or products?
After we assign a verb and subject to each THAT clause, they are not available to be a subject or verb in the main clause.

That-clause #1: [products] that ACME has developed
Subject? ACME (Company)
Verb? HAS developed.
-- Correct. The corporation is singular. "Corporation" in the company's name is not plural and
-- at the end of the sentence we learn that the company HAS [singular] lost focus.

AND
That-clause #2: [products [that]] . . . have recently arrived
Subject? Products
Verb? have arrived

One way to find the verb of the main clause, then, is to make sure that each that-clause has its verb (and its subject).
In this sentence it's easier to work from inside out.

Subject of the main clause? quality
Verb in the main clause? worries


I hope that analysis helps. If you still have questions, I am happy to try to help.

Hi generis egmat hazelnut VeritasKarishma

I read the explanations but I couldn’t understand one thing , the quality of products and the products that arrived on retailer’s shelves - these are 2 things then why we have used “worries” ? It should be worry

Plz explain

Posted from my mobile device

This is the structure:

The quality of the products ... worries many business analysts ...

Which products?
The new products
-that ACME Corporation have developed over the past year
-and that have recently arrived on retailers’ shelves

These new products ACME developed over the year and they have recently hit retailers' shelves

The quality of these worries analysts. Quality is singular so will take worries.

Thankuuuuu I understood the point

the products -> is in Plural right? hence "and that HAVE recently arriaved on ..." has to be agree in verb (plural)

Best,

Gast??n
