The costs amounts to 100$
Usage of Lower vs Less?

That vs Those
The adjective lower is erroneously used in place of the noun less as object of the preposition to.

That is used for singular comparisons
Those is used for plural comparisons
Ex: income of X to that of Y
incomes of families X to those of families Y
Some one has invested X$ of money in research for developing X
(or)
Some one has invested X$ of money in research to develop X
(or)
Some one has invested X$ of money in research for X to be developed
Since they hope to develop somethings.Usage of "in research to" is correct. So B

Also usage of
Research for [Verb] is incorrect
Research to [Verb] correct.
Which one is correct?

cars that are more gasoline-efficient even than those at present on the road

cars even more gasoline efficient than those at present on the road
even and more should go together. So B.

A. than

B. than those of

C. than is so of

D. compared to

E. compared to those of
when "more " is used make sure it has a corresponding than...not compared to or something.
more...compared to is unidiomatic and redundant.
When a question is given in Dates in past, like 1204 until 1456. What should you look in answer choices
Remove answer choices that use present tense or that use anything not past.
Example: The Parthenon was a church from 1204 until 1456, when Athens was taken by General Mohammed the Conqueror, the Turkish sultan, who established a mosque in the building and used the Acropolis as a fortress.

E. establishing a mosque in the building and using the Acropolis as

B. who, establishing a mosque in the building,used the Acropolis like

In choices B and E establishing is used which is present tense. The correct choice needs to use "established"
Usage of Past Perfect "Had"
----------------------------------------
How does the below choice D, mean in general

The Parthenon was a church from 1204 until 1456, when Athens was taken by General Mohammed the Conqueror, the Turkish sultan, who established a mosque in the building and used the Acropolis as a fortress

D. who had established a mosque in the building,using the Acropolis to be
The choice mentions that the Turkish sultan had already established a mosque before he took athens. So D is wrong.
Using X to be Y
Used X as Y

Families where
vs
Families in which

Husband only was employed

B. of a family where only the husband

C. that for families in which only the husband

D. a family in which only the husband
Families are compared to family
because vs because of
because is a subordinating conjunction, so a sentence needs to follow after because.
because of is a preposition. Because of is followed by a noun.

Because of + Noun

Because + Sentence
due to and since usage
"due to" should function only as a complement:

The fire was partly due to the lack of rain.

but NOT

Due to the lack of rain, a fire broke out.

GMAT tends NOT to like "since" because "since" has two meanings: "because" and "after," so be wary of choosing answers with "since." (Remember, these are just guidelines and strategies, okay?? NOT firm rules!!)
fewer vs less
---------------------
Only seven people this century have been killed by the great white shark, the man-eater of the movies—less than those killed by bee stings.

* movies—less than those
* movies—fewer than have been
* movies, which is less than those
* movies, a number lower than the people
* movies, fewer than the ones
less for non-countable (Less Money)

fewer for countable

Answer: E.

A,C,D use Less and lower which are non-countable. Between B and E, B has have been killed which is present perfect, now do the bees still kill people now. The main sentence compares present to past. So E
double vs twice

Question:168 Today, because of improvements in agricultural technology, the same amount of acreage produces {{double the apples that it has}} in 1910.
double the apples that it has
twice as many apples as it did
as much as twice the apples it has
two times as many apples as there were
a doubling of the apples that it did
double - Adjective
twice - Adverb
An adjective cannot modify a verb. While an adverb can!!
Produces is the verb, it modifies Twice. In the SC, did represents produced.
bodies burning vs bodies' burning?
which is a correct choice.
bodies' burning is correct format. The gerund burning needs a subject, so apostrophe needed.
due to vs because
due to means attributable to.
because means giving reason. because follows a clause.
More common among X than Y
More common among X than among Y
More common among X than common among Y

What should you check for when you see "was" in a sentence.

Ex: What was as remarkable as the development of the compact disc has been the use of the new technology to revitalize
Check for tenses in the underlined/non-underlined portions.

The sentence has two verbs was and present perfect has been.
What is the difference between these two:

gain weight quicker than do those ...
gain weight more quickly than...
qain weight is verb. quicker is adjective, more quickly is adverb. An adverb is used to modify a verb. So, gain weight more quickly than others.... is correct!!
worried about vs worried over or worrying over; -- Which one is chosen for describing a condition rather than an action
Worried About

Whats wrong with the below sentence

Never before had taxpayers confronted so many changes at once as they had in the Tax Reform Act of 1986
In the choice, the past perfect had [confronted] illogically places the 1986 events in the same time frame as Never before had...;
Correct Usage: Never before had taxpayers confronted so many changes at once as they confronted in the Tax Reform Act of 1986
What is the problem with the below sentences

B. confronted at once as many changes as

C. confronted at once as many changes that there were with
awkwardly placed "at once" between confronted and its direct object, "changes"

Correct Usage: confronted as many changes at once as they confronted in
Words that use to be

Analyze

In 1973 mortgage payments represented twenty-one percent of an average thirty-year-old male's income; and forty-four percent in 1984 .

A. income; and forty-four percent in 1984

B. income; in 1984 the figure was forty-fourpercent

C. income, and in 1984 forty-four percent

D. income, forty-four percent in 1984 was the figure

E. income that rose to forty-four percent in 1984
A. Usage of semicolon is wrong. After a semicolon a clause should come not phrase. When comparing two circumstances in 1973 to those in 1984, a seperate clause is needed to describe each year. Clause is something with a verb and subject. A uses a phrase not a clause to do the comparison.
B. Correct
C. Seperate clause needed
D. A semicolon is needed not a comma for different clauses
E, that refers to income there by mentioning its the income than the mortgage payments that increased.
1. Capability and Can cannot go together

The correct rule is Claims is followed by an infinitive. So both are correct, but the perfect form of claims is claims + to

claims + to have
claims + to be
Which is correct and why:

cost business ...
to business is awkwardly inserted between cost and the prepositional phrase that modifies it. Its also wordy.
Restitution... to
Restitution... for
Restitution...for
Expected to rise
Expected for it to rise
Expected that it will rise
Expected to is the correct Idiom

Prefer as many as for countable and equivalent to for non-countable
Whats the difference between these two?

C. a meteorite will strike one human being oncein every nine years

D. every nine years a human being will bestruck by a meteorite
the language of C implies more than can reasonably bemaintained: i.e., that a meteorite will strike one person, and noone else, exactly once during every nine-year period. Choice D is best: the phrasing is concise and free of unintendedsuggestions, and the use of the indefinite article in a humanbeing is appropriate for describing what is expected to be trueonly on the average.
whats the difference between
One Human Being vs a Human being
One means exactly that person
a is an indefinite article not pointing exactly to that person.
What is the problem with this sentence:
Intar,the oldest Hispanic theater company in NewYork, has moved away from the Spanish classics and now it draws on the works
it intrudes between the halves of thecompound verb has moved... and [now] draws to introducea new grammatical subject, thereby creating a run-onsentence:the inclusion of it requires a comma after classics to set offthe new independent clause.
Economic vs Economical
Economic means pertaining to economy
Economical means frugal, spending carefully
In English, the idiom is

requiring x to y or

requiring that x y,

with x as the noun subject and y the unconjugated form of the verb.
requiring employers to retain all older workers
What is the difference between B and E, other than the idiom thing?

Senator Lasker has proposed legislation requiring that employers should retain all older workers indefinitely or show just cause for dismissal.

B. that all older workers be retained by employers

E. employers to retain all older workers
in B, the awkward shift to the passive construction makes workers the subject of show, thus producing the unintended statement that older workers [rather than employers} are required to show just cause for dismissal.
Both the choices are wrong why? [Hint: Use Parallelism]

the retaining by employers of all older workers indefinitely or show just cause for dismissal.

vs

employers' retention of all older workers...or show just cause for dismissal.
Parallelism is the main problem

Choices C and D are ungrammatical because the retaining and retention function as nouns, which cannot be joined by or to the verb show: grammar requires that the compound predicate consist of two verbs, retain... or show.
Whats the problem here:

Mystic Guided
Mystic and also Guided
Mystic and that he was guided
mystic and that he guided
This is a common pattern in gmat, to keep words in between.Mystic guided is correct
which is correct one and why:

collateral to borrowagainst to get through

What is the problem with D?

With only 5 percent of the world's population, United States citizens consume 28 percent of its nonrenewable resources, drive more than onethird of its automobiles, and use 21 times more water per capita than Europeans do.

D. Despite having

E. Although accounting for
Despite having in choice D confusingly suggest that United States citizens somehow possess, rather than constitute, 5 percent of the world's population
What is the subject of a sentence makes a big difference in GMAT

A number of linguists contend that all of the thousands of languages spoken by the world's five billion people can be traced back to a common root language.

A. that all of the thousands of languages spoken by the world's five billion people can be traced

B. that the world's five billion people speak thousandsof languages of which all can be traced

What is the subject in A and B?
A: all languages
B: People
Next to contend we need main subject, which is all languages, so A. also A precisely indicates the relationship of the thousands of languages to the common root language (they can be traced back to it).
Which is correct
all of which
of which all..
All of which
Analyze
Dirt roads may evoke the bucolic simplicity of another century, but financially strained townships point out that dirt roads cost twice as much as maintaining paved roads.

A. dirt roads cost twice as much as maintaining paved roads

B. dirt roads cost twice as much to maintain aspaved roads do

C. maintaining dirt roads costs twice as much aspaved roads do

D. maintaining dirt roads costs twice as much as itdoes for paved roads

E. to maintain dirt roads costs twice as much as for paved roads
This sentence compares the costs required to maintain two kinds of roads. B, the best choice, is able to maintain parallelism in the comparison as well. Choice A incorrectly shifts the meaning by comparing the cost of dirt roads with the cost of maintaining paved roads. Choice C does the opposite: it compares the cost of maintaining dirt roads with the cost of paved roads themselves. Choice D further confuses the sentence by adding a nonparallel clause, it does for, in which it has no clear referent. Choice E introduces the infinitive phrase to maintain... and wrongly attempts to complete the comparison with the nonparallel prepositional phrase for....

whose is better than using in that their or because
density ...more numerous
density...greater than
density is a mass noun, only greater than goes with mass nouns.

numerous- modifies countable nouns
greater - modifies non-countable nouns

timber wolf is not dense, its population is dense.
In these kind of questions what should be your point of view:

Tennessee adopted a child-passenger protection law requiring

C. that parents restrain children under four yearsof age in a child safety seat

D. that children be restrained under four years ofage in a child safety seat by their parents
You should stop and ask the question what is the meaning of the sentence

1. Who restrains whom?
2. What would be possible subject.

If a sentence doesnt fall into any of the categories, like, SV, Verb, Modifiers, pronouns, parallelism. Immediately you gotta think about the meaning.
1. infrequently enough that
2. so infrequently that

Wrong Usage of has/have/having in a sentence.

In OG I have observed that usage of has/have/having is wrong in some instances. has have having me to possess, to possess inherently

1. Despite having 30% population in USA (How can USA inherently possess something)
Correct: Although accounting for 30%...

2. a community
where they have 49 percent of the household incomes

which has 49 percent of the householdincomes

in which 49 percent of them have household incomes

All the above sentences are wrong usage of has/have. it means they possess!! THe correct sentence is:
where 49 percent of the household incomes are
What are the rules when you are defining a book?
Ex: The Adventures of Huckleberry Finn
Rules:

1. A book name should precede with "That"

As a result of medical advances, many people that might at one time have died as children of such infections as diphtheria, pneumonia, or rheumatic fever now live well into old age.

A. that might at one time have died as children

B. who might once have died in childhood
B, the best choice, uses the preferred relative pronoun, who, to refer to many people. It observes formal and logical parallelism in the wording of the relative clause and the main clause: first, adverbs (once and now)', second, verbs (might have died and live); and third, adverbial prepositional phrases (in childhood and into old age).
What is an appositive

Ex: Presenters at the seminar, one who is blind, will
An appositive is a noun or noun phrase that renames another noun right beside it. The appositive can be a short or long combination of words. Look at these examples:

The insect, a large cockroach, is crawling across the kitchen table.

The insect, a large cockroach with hairy legs, is crawling across the kitchen table.

The insect, a large, hairy-legged cockroach that has spied my bowl of oatmeal, is crawling across the kitchen table.

Teratomas are unusual forms of cancer because they are composed of tissues such as tooth and bone not normally found in the organ in which the tumor appears.

A. because they are composed of tissues such as tooth and bone

B. because they are composed of tissues liketooth and bone that are

C. because they are composed of tissues, liketooth and bone, tissues

D. in that their composition, tissues such astooth and bone, is

E. in that they are composed of tissues such as tooth and bone, tissues
Read the explanantion

Only E, the best choice, clearly states that teratomas consist of tissues such as tooth and bone, and that such tissues are not normally found in the organ with the teratoma. Clear statement of this fact requires the repetition of tissues to establish the appositive--tissues normally found.... Without such repetition, A and B imprecisely state that the tooth and bone, as opposed to the tissues, are not normally found in the affected organ. Choices B and C alter the meaning with the use of like', that is, they suggest that the tissues are not tooth and bone, but only like them. The confused syntax of D states that their composition, not the tissues, is found in the organ....

In April 1997, Hillary Rodham Clinton hosted an all-day White House scientific conference on new findings that indicates a child’s acquiring language, thinking, and emotional skills as an active process that may be largely completed before age three.

A. that indicates a child’s acquiring language, thinking, and emotional skills as

A)the largest share for any country to contribute
B)the largest share that any country has contributed
A is correct choice here, since

A march 2000 Census Bureau - Some thing of a specific time, Means Past Tense. So "has contributed" present perfect tense is wrong.

So when Since is there dont rush and select has + ed, check at whcich time the sentence belongs to.
