 Question

Unlike most other species of cat, regardless of being domesticated or not, the claws of the tiger are not retractable and so it is more like a dog in that way.
A) regardless of being domesticated or not, the claws of the tiger are not retractable and so it
is more like a dog in that way
B) domestic or wild, the tiger does not have retractable claws and so is more like a dog in that
respect
C) regardless of domestication or not, the tiger's claws are not retractable and so it more like
a dog in that respect
D) domestic or wild, the claws of the tiger are not retractable and so it is more like a dog in
that way
E) domestic or wild, the tiger does not have retractable claws and so they are more like a
dog's in that respect

Solution

Answer B

When you have to choose between 'regardless of being domesticated or not' and 'domestic or wild' you can easily eliminate 'regardless of being domesticated or not' for not being concise. So you can eliminate A and C.

In option D the verb 'are' is used for 'the tiger' so it is wrong.
In option E the use of 'have' for singular 'the tiger' is wrong.

So we are left with answer choice B, which is the correct choice.

Use of a Infinitive and a Participle

Use of a Infinitive and a Participle 

 Choosing between an infinitive and a participle, this is another type of question on the GMAT sentence correction questions.  In this type of question after eliminating all the obvious errors you will be struggling between two options; one will have an infinitive and the other will have a participle.

Like you may have to directly choose between 'to run' and 'running'. Both may sound equally correct to your ears, but only one of the two options is correct. Do not worry, in such a situation  we need to memorize a simple rule.

The Rule

An infinitive is almost always used to show intention or desire, whereas a participle is almost always used to show the result or effect of something. So use a present participle to show effect and infinitive to show intention.

Example,

Sentence 1: Sheldon drove his truck at 170 miles an hour, causing an accident.

Sentence 2: Sheldon drove his truck at 170 miles an hour to cause an accident.

In the sentence 1 the present participle 'causing' express the result or effect of driving at 170 miles per hour, whereas in the second sentence 'to cause' clearly suggests that Sheldon drove his truck at a particular speed with the intention of causing an accident.

Important Note: Here when you read the sentence, you need to understand the meaning of the sentence. Once you understand the meaning of the sentence it is very easy to decide between an infinitive and a participle.

 Question

Rising raw material costs is only one of the factors, albeit an important one, that keeps the housing market from spiraling out of control, like it did earlier in the decade.

A) keeps the housing market from spiraling out of control, like it did

B) keep the housing market from spiraling out of control, as it did

C) keeps the housing market from spiraling out of control, as it did

D) keep the housing market from spiraling out of control, like

E) keep the housing market from spiraling out of control, like it did

Solution

Answer B

Remember the following rule

On the GMAT for sentences like this where the subject is "one of the factors ... that keeps.." you can follow this simple rule.

If you see the sentence in the form of

One of the Noun (Here Noun is always PLURAL) .... that/who ..... PLURAL VERB.

If you see the sentence in the form of (where that/who is not used in the sentence).

One of the Noun (Here Noun is always PLURAL) .......SINGULAR VERB.



The original sentence states that "a higher interest rate is only one of the
factors...that keeps..." The clause "that keeps the housing market from
spiraling out of control" is describing the word "factors." Since "factors" is plural
noun and "keeps" agrees with singular nouns, we need to find a sentence that
replaces "keeps" with "keep". Also, "like it did earlier in the decade" is
incorrect. When comparing clauses (i.e., a phrase containing a subject and
a verb), we must use "as" instead of "like." For example, "She sings like her
mother" and "She sings as her mother does" are both correct, but "She sings
like her mother does" is not.

Question

The National space probe recently published a report cautioning that many of the space rubble to which satellites and spacefaring vessels are exposed pose a significant risk of damaging or destroying satellites and vessels in instances of accidental impact.

a) many of the space rubble to which satellites and spacefaring vessels are exposed pose

b) many of the space rubble that satellites and spacefaring vessels are exposed to poses

c) many of the rubble that is in space and that satellites and spacefaring vessels are exposed to pose
d) much of the rubble that is in space and satellites and spacefaring vessels are exposed to poses

e) much of the space rubble to which satellites and spacefaring vessels are exposed poses

Solution

Answer D

 

This is a easy rule to remember and a sure short question that helps a GMAT test taker can score a point. 

“Much” and “many” are commonly confused words. “Many” is right for countable quantities and is plural; “much” is correct when discussing unquantifiable amounts and is singular. Since it would be virtually impossible for someone to try to count space rubble, this sentence should contain “much.”

And since "much" is singular, its verb should be, too ("poses"). But be careful: even though "much is singular, "satellites and spacefaring vessels" is a compound-- and therefore plural-- noun, so "are exposed" is correct. Now choose the option that is clear, concise, and correct. 

 

Introduction to Critical Reasoning on GMAT

Introduction to Critical Reasoning on GMAT

The focus of the critical reasoning Questions on the GMAT test is test how good are you in analyzing fact sets from a bunch of lines. On, age, you have 1 minute and 45 seconds to complete each question. So sometimes the pressure goes really high when the paragraph is little longer or when the paragraph is to confusing. The GMAT is a structured test so it will test you on a predictable pattern. In critical reasoning, there are certain question types that are tested again and again.

A typical GMAT critical reasoning Question

Every critical reasoning question that you see on the GMAT will have three parts to it:

1) The Stimulus,

2) The Question Stem, and

3) The Options

Now that you know the structure of an actual GMAT Question on the GMAT test, you are ready to know what are the components of an argument.

Components of an Argument

Every argument in a critical reasoning question on the GMAT test has three pasts.

1) Evidence or stated facts

2) Conclusion

3) Assumptions

You need to remember that

EVIDENCE + ASSUMPTION leads to (=) CONCLUSION.

Almost every question will be missing the ASSUMPTION part, that is the test takers will have to analyze the assumption based on the evidence and conclusions. Sometime, it may also happen that the stimulus will be just a collection of facts and no conclusion will be provided. In such cases, it will be most likely that the question stem will ask you to find the conclusion from the options.

Assumption

The stimulus will usually appear in two forms - as an argument or as several statements of facts and the hidden assumption. You need to understand that assumptions are a critical part of GMAT critical reasoning. Just think it in this way, every author who ever writes an article or an argument is always based on some prior assumption that he or she makes.

For example:

In response to the increasing cost of producing energy through traditional means, many utility companies have begun investing in renewable energy sources, chiefly wind and solar power, hoping someday to rely on them completely and thus lower energy costs. As one can easily see, these sources will be less risky for the utilities than nonrenewable sources, such as gas, oil, and coal, whose prices can fluctuate dramatically according to availability.

So what do you think is the assumption behind this argument. Here are few assumptions on which this argument could be based on:

(i) Running cost is low or negligible in using renewable energy sources

(ii) One can predict weather patterns

Conclusion

Always start by reading the stimulus. Some students prefer reading the question stem first but I see that as waste of time because you will read the question stem, then read the stimulus and then habitually read the question steam again. You should take an average of two minutes to answer each critical reasoning question. This is an average and not hard and fast rule. Some questions may take more and some may take less.

Question

Found on several Indian subcontinent, Bengal Tigers dominate their habitat, and grow to lengths of up to 6 feet, running swiftly enough that deer and wild boar serve as its primary live prey.

A) Bengal Tigers  dominate their habitat, and grow to lengths of up to 10 feet, running swiftly enough

B Bengal Tigers dominate their habitat and grow to lengths of up to 10 feet, and with such swift running

C) Bengal Tigers dominate their habitat and grow to lengths of up to 10 feet, they run swiftly enough

D) the Bengal Tiger dominates its habitat, growing to lengths of up to 10 feet and running so swiftly

E) the Bengal Tiger dominates its habitat, grows to lengths of up to 10 feet, and it runs swiftly enough

Solution

Answer D

This sentence contains errors in pronoun agreement. The plural “Bengal Tigers” and the referent "their" do not agree with the singular “its” in the non-underlined section of the sentence. Therefore, “Bengal Tigers” must be replaced by the singular “Bengal Tiger” and "their" by "its." Next, the present participle form of a verb (-ing) is appropriate when the word or phrase is used as an adjective or in an adjectival phrase, so "growing" and "running" are preferable and appropriate since they refer to the Bengal Tiger's domination of its habitat. Finally, the phrase “running swiftly that” is not the correct idiom. The correct construction is “so x that y,” or “running so swiftly that deer…”

d) it should implement its

e) to implement its

ANSWER E

Solution

The GMAT loves prepositional parallelism.  In fact, generally, the GMAT likes to repeat the very same preposition--"with," "after," "against," whatever--to emphasize parallelism, even when they don't have as good a reason as they do here.

There are actually two ways to use the preposition "to" to accompany a list of infinitive verbs.  You can repeat the "to" with each verb: "I like to eat most of the day, to sleep most of the night, and to watch cartoons whenever I'm not eating or sleeping."  Or you can distribute the "to" over the entire list: "I like to eat most of the day, sleep most of the night, and watch cartoons whenever I'm not eating or sleeping."  On the GMAT, the credited response will almost always repeat the "to," rather than distributing it.  The only likely exceptions are when the phrases that form the list are very short, just one or two words, such as, "I like to eat, sleep, and watch cartoons."

OK, so that means we expect the word "to" to start the underlined section. 

 Only answer choice E starts with "to."

By the way, the the singular subject, “Australian Forest Service” must be referred to by a singular pronoun.

Relative clauses on GMAT

Relative clauses on GMAT

A relative clause gives more information about someone or something referred to in a main clause.

On the GMAT, a common way of confusing students with Fragments is by using relative clauses in a sentence. Consider the following example:

Sentence 1: The fruit is lying in the basket.

Sentence 2: The fruit that is lying in the basket.

Sentence 3: The fruit that is lying in the basket is ripe.

Here Sentence 1 is complete, Sentence 2 in incomplete and Sentence 3 in complete.

Sentence 2 : Incomplete

Let us examine Sentence 2:

(Reference: A clause is a group of words that contains both a Subject and a Predicate, but may not be able to stand on its own. So, usually a relative clause requires an anchoring of a complete sentence).

In Sentence 2 that 'is lying in the basket' is a dependent clause and requires anchoring of a complete sentence, which is missing in this case.

Sentence 3: Complete

So to complete the sentence we move to sentence 3.

Consider this:

The fruit is ripe. (This is a complete sentence)

now add the relative clause <that is lying on the table>

Sentence 3: The fruit <that is lying in the basket> is ripe.

Note:  Simple rule for use of Relative clause

• ·         We prefer to put a relative clause immediately after or as close as possible to the noun it adds information to.

•       When we use a defining relative clause, the relative pronoun can be the subject or the object of the clause.

More on relative clause on the coming blogs.

Main Point:

On, the real GMAT, you will see very long sentences which are incomplete and they miss the most important part of the sentence that is VERB.The test makers always try to confuse you with a relative clause, which has a verb.

How do identify the missing verb - eliminate the relative clause and you will easily find the missing verb.
