hi,
when i was solving this question , i eliminate option A as there is a clause in preposition,
Because of < Clause> ,
Since it is a official question , the answer is absolutely correct,
but i have seen the following structure all the time
Because of Noun/ Noun entity or Because <Clause >
So my question is,
Is the above statement an exception?
or the usage in OA is absolutely correct
Thanks
Option A: Because of the erratic pattern of sales increases this year,
retailers and analysts hesitate to predict five-year trends in retail sales during the months that have historically been the most profitable.Hi
cool16 ,
No, option A is not an exception.
(And kudos for not "fighting" with the official answer.)
Option A does not have a clause with a subject and a verb after
Because of.
The underlined words are a noun phrase (a noun + modifiers).
You got tripped up by "sales increases."
That phrase is a noun. (The two words could not be a subject and verb;
sales is plural and
increases is singular.)
• "SALES INCREASES" - nouns that modify nounsIn English, we use nouns to modify nouns:
Spanish teacher
Sports car
Race horse
Corn bread
sales increases is a
noun.
Increases is a noun, not a verb.
And
increases is modified by the "noun-adjective"
sales (What kind of increases?).
generis,
Hi, I found pattern is the subject and increases is the verb.
Because of the erratic pattern of sales increases this year..........
Ho come increases is the noun. Example- he increases his score by 5 marks. Increases works as a verb. Please help me on this. I eliminated option A because because of + noun +
immediate verb is usually wrong in GMAT.
Hi
sunny91 ,
I think you are asking the same question whose answer you are quoting.
Let me try to explain a different way.
First, you are correct.
Because of is a preposition that needs a noun. (Because of WHAT?).
Prepositions can be followed only by a noun, noun phrase, or pronoun.
You think that
Because of is followed by a clause whose subject is
pattern and whose verb is
increases. No.
The highlighted part is incorrect, though I understand why you think that "increases" is a verb: often it IS a verb.
Pattern is not followed by a verb.
Pattern is followed by a preposition (OF) + noun (increases)
How do we know? The word OF.
Pattern OF.
OF is a preposition that MUST be followed by a noun.
So when we see a preposition, OF, and a word such as "increases" that could be a verb OR a noun, we must think, "That word should be a noun. IS that word a noun?"
Quote:
How come increases is the noun.
Increases is a noun because
(1) it follows the preposition OF (which requires a noun, so "increases"
should be a noun),
(2) it IS a noun at times,
(3) some noun must follow OF, and
(4) It makes sense.
The structure of the prepositional phrase will not allow "increases" to be a verb. We cannot ignore the OF.
If
pattern were a subject, OF could not come between
pattern and the verb
increases.
-- Subject/verb:
The pattern increases. (Weird, but a grammatical subject and verb. No OF.)
-- NOT a subject/verb:
The pattern OF increases. 
There is no such noun as "pattern of."
Pretend the main clause is different. I'll use different verbs that cannot also be nouns.
Because of the pattern of writes

Because of the pattern of weeps
TWO prepositional phrasesIn other words, we have
two prepositional phrases back-to-back:
(Preposition) +
noun1) (BECAUSE OF) a
pattern2) (OF)
sales increasesLet's try some different words.
Because of the erratic pattern of purchasing habits, retailers and analysts hesitate to predict five-year trends in retail sales during the months that have historically been the most profitable.

Correct, back to back prepositional phrases:
(1) preposition + noun
[Because of] + [the erratic pattern]
(2) preposition + noun
[
of] + [purchasing habits]
"Purchasing habits" is a noun phrase. That fact is easy to see.
"Sales increases" is also a noun phrase. That fact is not as easy to see, in part because
English uses nouns as adjectives sometimes.

[/quote]
Increases can be a verb OR a noun.
Notice that you cannot write
"He
of increases his score by 5 marks."
I'm not saying that
increases is never a verb.
I'm saying that
increases is not a verb in this sentence.
"Increases" can be a verb sometimes.
But "can be sometimes" does not equal "must be always."
Takeaway: Prepositions can be followed by
only a noun, pronoun, or gerund (verbING).
If a word seems to be a verb (and is
not an __ING word), does a preposition come right before the "verb" in question. Yes? Then that word cannot be a verb.
If you are still confused, try explaining to me why increases IS NOT a noun.
Or ask another question. I'm happy to try to help. This sentence is hard.
I hope that helps.
