Shorter is better

This one of the key rules to know for both the ACT English Test and the SAT Writing and Language Test. Both of these tests place a strong emphasis on conciseness — namely, that short, clear constructions are preferable to long, wordy ones. When you are given a phrase rewritten several ways, all of which are grammatically correct, the shortest one will virtually always be right.

As a result, you should always start by checking the shortest answer and consider the longer ones only if it clearly does not fit.

Note that this rule applies only to general non-grammar question, NOT ones that require you to give a sentence a particular focus (e.g.” Which of the following most effectively emphasizes the author’s surprise at discovering a frog in her living room?”)

While some incorrect answers will simply include extra, unnecessary words, many others are incorrect because they are redundant.

Example #1

Incorrect: I decided to ask my mother a question, which required an answer.

Correct: I decided to ask my mother.

The only thing that one can ask is a question; and a question, by definition, requires an answer, so the inclusion of this information is unnecessary.

Example #2

Incorrect: In 2016, a bright purple ribbon glowed over Alberta, Canada, and the scientists who study aurora borealis—the northern lights—were unaware and did not know that it was even there.

Incorrect: In 2016, a bright purple ribbon glowed over Alberta, Canada, and the scientists who study aurora borealis—the northern lights—were unaware that it was even there.

By definition, people who are “unaware” do not know something, so it is unnecessary to include both.

 

Comma splices and how to fix them

Comma splice = two sentences separated by a comma

Rule = comma splices are always wrong

The comma splice is one of the most frequently tested errors on both SAT Writing and ACT English. Comma splices trump all other stylistic issues, which means that no matter how good a sentence sounds otherwise, it cannot be correct if it contains one.

Note that the most common tip-off for this error is “comma + pronoun” (he, she, it, they).

Comma Splice: Anna Robertson (“Grandma”) Moses only began painting at the age of 78, she achieved fame as an artist.

 

The four most common ways to fix comma splices are as follows:

 

1) Add a coordinating conjunction after the comma

Coordinating Conjunctions: For, And, Nor, But, Or, Yet, So

Correct: Anna Robertson (“Grandma”) Moses only began painting at the age of 78, but she achieved fame as an artist.

 

2) Replace the comma with a period or semicolon

A period/semicolon can be added alone or, more commonly, a conjunctive adverb (however, therefore, nevertheless, moreover) can be placed after the period or semicolon in order to make the relationship between the clauses clear.

Correct: Anna Robertson (“Grandma”) Moses only began painting at the age of 78; she achieved fame as an artist.

Correct: Anna Robertson (“Grandma”) Moses only began painting at the age of 78; nevertheless, she achieved fame as an artist.

Correct: Anna Robertson (“Grandma”) Moses only began painting at the age of 78. However, she achieved fame as an artist.

 

3) Make one of the clauses dependent by adding a subordinating conjunction (although, because, while)

Correct: Although Anna Robertson (“Grandma”) Moses only began painting at the age of 78, she achieved fame as an artist.

 

4) Add a participle  

Correct: Anna Robertson (“Grandma”) Moses only began painting at the age of 78, achieving fame as an artist.

 

Tip: whenever you see answer choices that include a semicolon, a period, and a comma + and/but, you can automatically eliminate all of those options. They are exactly equivalent to one another, and you will never be asked to choose between two equally correct answers.

Semicolon = Period

I find that a lot of people are afraid of semicolons. Either that, or they sort of kind of think they might have an idea about how to use them… From what I have observed, semicolons are probably the most misunderstood punctuation mark. And that’s very unfortunate because they’re actually very simple to use. They also show up on the SAT and ACT English a whole lot.

Here’s the rule: semicolon = period

That’s it. Seriously. Wherever you can use a period, you can also use a semicolon.

Easy, right?
