Only one that seems acceptable is B.

A. a phenomenon that is explained not just because of more expensive drugs but by the fact that doctors are writing
because of / by the fact that

C. a phenomenon occurring not just because of drugs that are becoming more expensive but because of doctors having also written
Mixture of tenses

D. which occurred not just because drugs are becoming more expensive but doctors are also writing
Mixture of tenses / needs "also because" before doctors

E. which occurred not just because of more expensive drugs but because doctors have also written
"because doctors have also written" instead of "also because doctors have written"

The correlative conjunction- not only … but also has several other avatars. They are

1. Not only… but also
2. Not only by … but also by
3. Not only because …. But also because
4. Not only because of … but also because of
5. Not just… but also
6. not just by…. But also by

and so on with the additions of because, because of etc, all of them valid structures very often seen in GMAT

not just by …… but also by is equal to -not only by …. But also by- . There is not much different to see through both of them.

In that case, the correct version of the text would be


a phenomenon that is explained not only because of more expensive drugs but also because of the fact that doctors are writing


or

a phenomenon that is explained not only by the fact that drugs are becoming more expensive but also by the fact that doctors are writing

This is the position as far as the use of // in correlative conjunctions is concerned.

In 2000, a mere two dozen products accounted for half the increase in spending on prescription drugs,
a phenomenon that is explained not just because of more expensive drugs but by the fact that doctors are
writing
many more prescriptions for higher-cost drugs.

below is the correct choice:

a phenomenon that is explained not just by the
fact that drugs are becoming more expensive
but also by the fact that doctors are writing



MY question is : regarding the subordinate clause in this question:

1. a phenomenon that is explained not just by the fact that drugs are becoming more expensive but also by the fact that doctors are writing

a phenomenon ...should start a subordinate clause(because it is after comma ),but I cannot find the verb after a phenomenon (the subject and verb are inside "THAT" clause)


2. but also by the fact that doctors are writing

but ...should start a subordinate clause ..here also no subject and verb (the subj and verb are inside "THAT"clause)

This is an example of "appositive modifier". This kind of modifier refer to either a specific noun or to the whole concept of the preceding clause; here because "a phenomenon" is an abstract noun we are in the second scenario, hence this modifier will refer to the whole clause.

1) Yes, it does have a verb
a phenomenon that is explained not just by the

2)Yes, there is a verb
but also by the fact that doctors are writing

the construct of the sentence is: a phenomenon that is explained not just by the fact that X but also by the fact that Y.

Hope it's clear

Oh, I got what you mean.

This appositive modifier is actually an appositive phrase, and keep in mind that an appositive modifier is a single noun.
Cesar, the roman emperor, conquered (...)<== this is fine, and " the roman emperor" is not a clause.

In 2000, a mere two dozen products accounted for half the increase in spending on prescription drugs, a phenomenon
now till here you have "a phenomenon", not really explanatory, the next part "that is explained not just (...)" modifies the noun "phenomenon"

In 2000, a mere two dozen products accounted for half the increase in spending on prescription drugs, a phenomenon(noun) + modifier
the resulting thing is something of this form noun+modifier which is a case of appositive phrase.

Hope I've explained myself well

Just to supplement excellent explanation from Zarrolou

A modifier can be a word (adjective, adverb), phrase (prepositional, noun), or clause (which, that). Here the sentence is using noun modifier.

Hope this helps

Actually clause starting with "a phenomenon" is not a clause at all!! It's a phrase. Let's take an example:

ajmalshams is studying for GMAT, a competitive exam.
- Hopefully it is easy for you to see that "a competitive exam" is a phrase (and not a clause).

Now lets look at the following sentence:

ajmalshams is studying for GMAT, a competitive exam that is tough to crack .
- Again, the above sentence, at the "core" is same as the previous one; just that the subordinate clause that is tough to crack is modifying a competitive exam. So, a competitive exam that is tough to crack still acts as a phrase.

Also, when Zarrolou says "appositive phrase", perhaps (s)he means "absolute phrase". In SC, it is very essential that test takers get very comfortable with "absolute phrases". Since the structure of "absolute phrase" is so "non-intuitive", GMAT loves to test on that. Few examples from OG:

#102, OG-13:
Yellow jackets number among the 900 or so species of the world's social wasps, wasps that live in a highly cooperative and organized society consisting almost entirely of females—the queen and her sterile female workers.

#38, OG-12:
In 1850, Lucretia Mott published her Discourse on Women, a treatise that argued for equal political and legal rights for women and for changes in the married women’s property laws.

The bold in these sentences is absolute phrase. There are many many other examples in official sources.

i am still confused about a modifying phrase.

I do understand what EducationAisle said.

For the example given, "I am studying GMAT, a competitive exam that is hard to crack." The modifying phrase "a competitive exam that is hard to crack" is modifying GMAT.
However, in this example, a phenomenon that.... is not modifying prescription drugs but the entire sentence. How is this correct? Can you give examples similar to this?

In 2000, a mere two dozen products accounted for half the increase in spending on prescription drugs, a phenomenon that is explained not just because of more expensive drugs but by the fact that doctors are writing many more prescriptions for higher-cost drugs.

Hello hyoeun87, you are correct. The intent of the example was to illustrate that a competitive exam that is hard to crack is a phrase and not a clause (as was the perception of the user earlier).

Indeed, and this is a very common structure, extensively tested on GMAT. Few official examples from the Official Verbal supplement:

#75: Scientists have observed large concentrations of heavy-metal deposits in the upper twenty centimeters of sediments from the Baltic Sea, findings consistent with the growth of industrial activity in the area.
- Absolute modifier findings consistent with... modifying the entire previous clause.

#100: Sixty-five million years ago, according to some scientists, an asteroid bigger than Mount Everest slammed into North America, an event that caused the plant and animal extinctions that mark the end of the geologic era known as the Cretaceous Period.
- Absolute modifier an event that caused.... modifying the entire previous clause.

p.s. Our book EducationAisle Sentence Correction Nirvana discusses Absolute modifiers, its application and examples in significant detail. If someone is interested, PM me your email-id, I can mail the corresponding section.

dear experts,
I am confused with absolute phrase and appositive phrase.

any expert can point out how to distinguish these two different modifiers?

I compared these two modifiers, I figured out that absolute phrase can be placed anywhere of the sentence, while appositive phrase only followed a noun which will be modified.

is this way valid?
is any other way to approach?
how to distinguish these two modifiers?

thanks a lot
have a nice day

Absolute phrases have the following structure: noun + noun modifier. They modify the whole clause in some way.
I have heard about the event just yesterday, the event that rocked the nation. (noun = event, noun modifier= that rocked the nation - modifies the whole clause)

Appositives consists of just a noun (or a noun phrase). Appositives are noun modifiers (i.e. a noun modifying another noun).
Tommy, my little brother, has done this. (noun phrase = my little brother - no modifier for my little brother - modifies Tommy)
