VERB Patterns

Pattern 1

A recent study has found that within the past few years, many doctors have elected to retire early rather than face the threats of lawsuits and the rising costs of malpractice insurance.

Pattern 2:
Alternatives presented in the expressions X rather than Y, and X instead of Y should be parallel in form

Had Elected Early Retirement instead of facing ; Had elected early retirement rather than facing
The above two sentences donot form a parallel. since X and Y donot match.
have elected to retire early rather than face would be correct sentence that match X and Y

Pattern 3: Check for passive voice constructions in the main question. Hints to Passive voice are the usage of "by"

In astronomy the term "red shift" denotes the extent to which light from a distant galaxy has been shifted toward the red, or long-wave, end of the light spectrum by the rapid motion of the galaxy away from the Earth

In the above sentence the usage of "by" --"by the rapid motion", indicates it is a passive voice, hence has+{be} +past+participle
so has been shifted is correct. Wrong answer would look like this.
to which light from a distant galaxy has shifted

Pattern 4: Sentence Fragment
Often visible as smog,ozone, formed in the atmosphere when hydrocarbons and nitrogen oxides, two major pollutants emitted by automobiles, react with sunlight.

ozone, formed in the atmosphere when is a sentence fragment.

we need is to form a good sentence.

Pattern 5: Adverb such as twice cannot act as an object of the preposition by.

The number of undergraduate degrees in engineering awarded by colleges and universities in the United States increased by more than twice from 1978 to 1985 .

Increased by more than twice (Incorrect)
more than doubled is correct

Also,
Increased more than two times, means, that the increase has happened on two distinct ocassions.
Was more than doubled, means , that some unnamed agent increased the number of degrees.

Pattern 6: If X happens Y will happen.

Pattern 7:
Salt deposits and moisture threaten to destroy the Mohenjo-Daro excavation in Pakistan, the site of an ancient civilization that flourished at the same time as the civilizations in the Nile delta and the river valleys of the Tigris and Euphrates.

Use the simple past tense flourished to describe civilizations existing simulataneously in the past. Usage of past perfect tense would be wrong here, since both the civilizations are existing parallely at the same time

Pattern 8:

Depends on whether (Correct)
Depends on if (Incorrect)

WHETHER is preferable in presenting the situation as possible rather than conditional or hypothetical.

Pattern 9:

The clause beginning Since 1986 indicates that the practice described in the second clause continued for some period of time

after it began. a present perfect tense is needed. Please make sure that the second clause is continued. Dont generalize that

when since is used you need a present perfect.

peaked....have slipped...since then

and slipped since then, many companiesbeing unable to pass on higher costs(Incorrect)

Pattern 25:

It is possible that Native Americans originally have migrated to the Western Hemisphere over a bridge of land that once

existed between Siberiaand Alaska.

here have migrated is wrong, since it resembles present perfect, something which is still happening, since its the past, we

need just migrated.
migrated to the Western Hemisphere over a bridge of land that once existed between Siberiaand Alaska.

Pattern 26:

Usage of Past Perfect

Pronoun Patterns

1 . Make sure you check these three when you find a pronoun

   1. Pronoun Antecedent
   2. Pronoun Agreeement
   3. Pronoun Case

Pronoun case, implies, that for personal, possessive form of pronoun the right pronoun is used

When a possessive noun is used a possessive pronoun is needed.

its and their are possessive forms of it and they subjective pronouns. Use its if the subject is a possessive pronoun.
Use their when the subject is possessive plural.

Janice and Me went to picnic together
Janice and I went to picnin together

here the subject is Janice and I so I is used instead of I, which is objective. Find the subject and see if the pronoun case of the subject is chosen.

Pattern 11

were first aired on evening radio in the 1920's,they were moved to the daytime hours in the1930's

Pattern 12. Persuaded X to [do] Y

You need to find the exact location of sentence flow, for parallelism, this way you will understand whether it needs a participle or a gerund or a verb. Look at the below example

Joan of Arc, a young Frenchwoman who claimed to be divinely inspired, turned the tide of English victories in her country by liberating the city of Orleans and she persuaded Charles VII of France to claim his throne.

here i HAVE assumed that, the split in the sentence is from by liberating an hence I chose the below answer from the choices

persuading that the throne be claimed byCharles VII of France
instead of
persuaded Charles VII of France to claim histhrone

if you see again, the choice you chose inturnly has couple of errors, like passive voice, be claimed by charles 7. sO when a choice is made make sure it doesnt have any other errors, as Pearson keeps atleast 2 errors in a wrong choice. A wrong choice always smells more bad.

Pattern 13. Usage of that;
I assumed that when somebody said something, use that to tell more about it when its needed. For this example

Judge Bonham denied a motion <to allow members of the jury to go home at the end of each day instead of to confine them> to a hotel.

here look at denied a motion, I thought using that would intensify and eliminated choices which donot fall into it, this way the correct answer was eliminated. Always, when eliminating, you need to have a clear rule from OG or SC, for removing it, dont go with the assumed ones are feel good one's. Remember low score the result, of such. be responsible
