What are the steps for answering sentence correction questions?’
steps for answering sentence correction questions
a. Read the sentence carefully, trying to identify an answer
b. If no error is apparent, ask yourself:
i. Is the sentence grammatically correct?
ii. Is the sentence properly structured
iii. Does the sentence use correct diction?
iv. If you find one or more errors, look for an answer that makes the corrections
c. If you cannot find an error, read the answer choices. Focus on the differences between each choice and the original. Often this will turn up an error that you overlooked
d. Eliminate choices that contain errors and choose from among those that remain.
What do you do if you an error is not readily apparent?
If you cannot find an error, read the answer choices. Focus on the differences between each choice and the original. Often this will turn up an error that you overlooked

What is the only key word that can join singular subjects to make them plural?
Only “and” can join two singular subjects and make them plural
How do you handle the singularity or plurality of two distinct words or phrases joined by correlatives: i.e. either-or, neither-nor,…?
When two distinct words or phrases are joined by the correlatives: either …or, neither…nor, not only…but also, the word or phrase nearer to the verb determines the number of the verb.
What must be true about pronouns with respect to the words they refer to?
Pronouns must agree with the words to which they refer
What must be true about pronouns with respect to their case (whenever a form of the verb "to be" is used)?
Pronouns must be in the correct case: Whenever a form of the verb “to be” is used (“were”), the pronouns on both sides of the verb must be subjects.
What must every pronoun refer to?
Every Pronoun must refer to a noun or to another pronoun
What must be true about tenses of verbs with respect to their case? (time wise)
Verb tenses must reflect the sequences of events
How do you handle elliptical verb phrases?
Elliptical verb phrases must be constructed properly: the omission of a word or words from a sentence. The verb may properly be omitted only if it is in the same form as another appearance of the same verb.
How do you handle a pronoun modifying a gerund?
A pronoun modifying a gerund must be in the possessive case.: a gerund is a verb ending in –ing that acts as a noun. Example: His running is obsessive. Her nail biting is gross.
What can modify verbs?

How do you handle it when you have imperfect options in the answers?
Imperfect Options: Sometimes you will need to locate the least offensive of your options. Some answers contain questionable or cluttered phrasing.
a. Always identify the grammatically correct choices before considering the effectiveness of expression i.e. eliminate the choices that have grammatical errors.
b. When stumped, use the differences among answer choices to eliminate the most offensive ones.
When should you use the passive voice?
The Passive Voice: Unnecessary or awkward uses of the passive voice almost always require correction.
a. The passive voice reverses the order of a sentence (object->verb->subject i.e. “the house was purchased by Rita”)

How do you handle dangling modifiers?
9. Dangling modifiers: sometimes you will need to add a modifier that will change the meaning of the sentence to make it correct

Watch out for “-ing” words at the beginning of a sentence--these often signal a dangling modifier. Take a look at this sentence: "When writing, modifiers can help you clarify your points." The first part of the sentence--“When writing”--is a dangling modifier. Why? Because the word that follows it--“modifiers”--doesn’t make any sense. Modifiers write? Really? Think about what the writer really wants to say: “When you are writing, modifiers can help you clarify your points.”

Fix dangling modifiers in two ways: by adding a subject into the modifier itself, or by adding the logical subject immediately after the modifier. Try both ways to see what works for your sentence; sometimes, both methods will work. “When writing, you can use modifiers to help you clarify your points.”

Beware passive verbs--they can lead to dangling modifiers. Passive verbs occur when you use a form of “to be” plus the past participle form of a verb, such as “was killed” or “were purchased.” Passive voice eliminates the actor in a sentence. Check out what happens when you use a modifier with passive verb: “Screaming wildly, the pumpkins were thrown by the boys.” Maybe in a Halloween movie, but in real life, perhaps not. The passive verb “were thrown” gives the modifier “Screaming wildly” nothing to modify. Fix it by changing the passive verb to active, clarifying who’s doing the action: “Screaming wildly, the boys threw the pumpkins.”

altered intent:

original sentence: red wine, the finding of recent studies, may prevent serious heart problems in many adults.

alters meaning: recent studies have found red wine to prevent serious heart problems in many adults.

this says that red wine does prevent heart disease instead of may prevent heart disease.

wordiness: past experience reveals that cancer patients rarely ever exhibit the exact same symptoms.

correct: experience reveals that cancer patients rarely exhibit the same symptoms

an adverb can modify what?
usually a verb but it also describe an adjective, another adverb, a preposition or a phrase
correct and explain:

My friend Katy is a real interesting person.
real modifies interesting.
interesting is an adjective, thus real must be in its adverb form really.

correct: my friend Katy is a really interesting person.
when do you use good vs well?
good is an adjective that modifies a noun:

Amy is a good person

Well can be used either as an adjective that means healthy or as an adverb that means competently

Amy is feeling well. - used as adjective
Amy writes well - used as adverb
Does an adverbial modifier need to be as close as possible to the word it is modifying?
no. When the word being modified is not a noun, the modifying phrase is called an adverbial phrase and does not need to touch the word being modified.
How can you tell whether a modifying phrase is adverbial?
if the modifier answers the question how? about a verb, it is an adverbial modifier.

However, it must not change the meaning of the sentence and not be ambiguous.
fix and explain:

we test-drove a car having engine trouble
it is an awkward construction.

correct: we test-drove a car that had engine trouble
what is preferable: a modifier ending in -ing or a relative pronoun (which, that, who, whose, whom) + simple verb?

which:
a modifier introduced by the word which can be removed from the sentence without the sentence losing any essential meaning.

that:
a modifier introduced by the word that is essential to the meaning of the sent.
what is usually used to set off non essential clauses from the main clause?
a comma

essential clauses are usually not set off with a comma.
if an answer choice differs from the original sentence in that it sets a clause apart with commas, how should you pick an answer?
ask yourself whether the sentence requires an essential or non-essential clause to preserve its logical meaning.

an essential phrase will NOT be set off by a comma.
in the gmat, if which refers to the action of the preceding clause.. what should you do?
look for a choice that links which properly with a noun antecedent or that reworks the sentence to avoid the use of which entirely


"which" can be used as a relative pronoun. i.e. it refers to the noun immediately preceding it - not to the action of the entire preceding clause.


thus "which" should refer to a noun, if it doesn't refer to a noun, then do the above.


example:

the police found the murder weapon, which made the prosecutor's job easier.

Here "which" refers to murder weapon when it should refer to the action of finding the weapon.

correct it by eliminating "which":

The police found the murder weapon, making the prosecutor's job much easier.

here "making" can only refer to a verb. i.e. "found"

when looking at parallelism errors, do all of the verbs in a sentence need to be parallel?
no. one set of verbs might modify the main verb. the members of that set need to be parallel however.
in looking at parallelism with forms of the word to be, what must you be careful of?
make sure both sides of the verb are parallel in structure and in meaning.

example1:

the attitudes of that politician always seem to be attacking the poor. -- incorrect

It is not the attitudes that are attacking, it is the politician that is attacking
correct: Because of his intolerant attitude, that politician always seems to be attacking the poor.

example 2:
the flower boquet was the husband's giving of love to his wife.

meaning is fine, but it is structurally incorrect.
correct: The flower bouquet was the husband's loving gift to his wife
when should you use the idiom X enough to Y
vs
so X as to Y ?
use X enough to Y
when X is the criteria by which an ability to achieve Y is measured:

example: Bob is tall enough to reach the top shelf

example:
Bob is so tall as to reach the top shelf.

the focus here is the consequence of bob's extreme height.

singular.

ex:
every dog has paws
every dog and cat has paws
each of these shirts is pretty
how do you handle the word 'each' when it follows the subject:

They each ____ great tennis players

singular or plural?
when 'each' follows the subject, it has no bearing on the subject.

They each are great tennis players

use plural since the subject is plural here
are the words 'majority', 'minority', 'plurality' singular or plural?
it depends on the context

if it is referring to many individual parts of the whole, then it is plural. If it referring to the whole itself, use the singular form.

singular

Do it

correct: she asked him several times to take out the garbage, but she wasn't sure he would do so.

The numbers of

when to 'lay' vs 'lie'
Lay or Lie?
Lay means "to place something down." It is something you do to something else. It is a transitive verb.

Incorrect: Lie the book on the table.
Correct: Lay the book on the table.
(It is being done to something else.)

Lie means "to recline" or "be placed." It does not act on anything or anyone else. It is an intransitive verb.

Incorrect: Lay down on the couch.
Correct: Lie down on the couch.
(It is not being done to anything else.)

The reason lay and lie are confusing is their past tenses.

The past tense of lay is laid.

The past tense of lie is lay.

Correct: I laid it down here yesterday.
(It is being done to something else.)

Incorrect: Last night I laid awake in bed.

The past participle of lie is lain. The past participle of lay is like the past tense, laid.

Examples: I could have lain in bed all day.
They have laid an average of 500 feet of sewer line a day.

Layed is a misspelling and does not exist. Use laid.
