PromptAnswer
When can you use a colon?Only after a complete sentence (independent clause); what follows can be a list, phrase, or clause.
When can you use a semicolon to join clauses?Only between two independent clauses (it acts like a period), or to separate items in a complex list.
What is a comma splice?Joining two independent clauses with only a comma and no conjunction — an error.
Name four correct ways to join two independent clauses.Period; semicolon; comma + FANBOYS conjunction; or a colon/dash if the second clause explains or expands the first.
What is an independent clause?A group of words with a subject and verb that can stand alone as a complete sentence.
What is a dependent clause?A group of words with a subject and verb that cannot stand alone (often starts with a subordinating word like "because" or "although").
Fix: "I love pizza, it is my favorite food." (SAT)Comma splice — replace the comma with a period, semicolon, or comma + "and."
Can a single dash join two independent clauses?Yes — like a colon, a single dash can follow a complete sentence to add emphasis or explain/expand on it.
What are paired dashes/commas/parentheses used for?To set off a supplement (extra, removable info); the two marks in the pair must match (both dashes, both commas, or both parentheses).
Fix: "My sister—who lives in Ohio, is a doctor." (SAT)Mismatched punctuation — use matching marks: "My sister—who lives in Ohio—is a doctor."
How do you find the true subject of a sentence for subject-verb agreement?Cross out prepositional phrases and interrupters; the verb must agree with what's left.
Fix: "The list of ingredients were long." (SAT)"was" — the subject is "list" (singular), not "ingredients."
Are collective nouns (team, jury, family, committee) singular or plural on the SAT?Singular — they take singular verbs and singular pronouns ("its," not "their").
Fix: "The team celebrated their victory." (SAT)"its" — a team is singular on the SAT.
"The number of students" — singular or plural verb?Singular ("The number of students is rising").
"A number of students" — singular or plural verb?Plural ("A number of students are absent").
Subject-verb agreement with "and": singular or plural?Plural — "and" combines subjects ("Tom and Jerry are friends").
Subject-verb agreement with "or"/"nor": which subject controls the verb?The subject closest to the verb ("Neither the coach nor the players were ready").
"Each" and "every" + noun — singular or plural verb?Singular, even when followed by "of the [plural noun]" ("Each of the boys is ready").
What is the basic pronoun agreement rule?A pronoun must match its antecedent in number (and gender, where relevant).
Is "Each student must bring their own laptop" acceptable on the digital SAT?Yes — singular "they/their" is accepted for an unknown or generic singular antecedent.
"Everyone brought their books, but Maria forgot hers." — any error?No error — "their" correctly refers to generic "everyone," and "hers" correctly refers to the specific "Maria."
Trigger words "for" and "since" (duration) pair with which verb tense?Present perfect ("has/have + past participle") — e.g., "She has taught for ten years."
"By the time" + a past-tense clause pairs with which tense in the other clause?Past perfect ("had + past participle") — e.g., "By the time we arrived, the show had ended."
What is the modifier placement rule?A modifying phrase must sit next to the noun it logically describes; otherwise it's dangling or misplaced.
Fix: "Walking to school, the rain soaked Jake." (SAT)"Walking to school, Jake was soaked by the rain." — the modifier must describe the person walking, not the rain.
What does apostrophe + s ('s) on a noun usually signal?Possession (singular), not a plural — e.g., "the dog's bone."
How do you form the plural possessive of a regular noun?Add s for the plural, then just an apostrophe — "the dogs' bones" (bones belonging to multiple dogs).
its vs it's"its" = possessive ("the dog wagged its tail"); "it's" = "it is/it has."
their vs there vs they're"their" = possessive; "there" = place/existence ("there is"); "they're" = "they are."
whose vs who's"whose" = possessive ("whose book is this?"); "who's" = "who is/who has."
your vs you're"your" = possessive; "you're" = "you are."
fewer vs less"fewer" for countable nouns ("fewer apples"); "less" for uncountable/mass nouns ("less water").
number vs amount"number" for countable nouns ("a number of people"); "amount" for uncountable nouns ("an amount of money").
then vs than"then" = time/sequence ("first this, then that"); "than" = comparison ("bigger than").
affect vs effect"affect" is usually a verb meaning to influence; "effect" is usually a noun meaning a result.
What is parallelism (parallel structure)?Items in a list or comparison must share the same grammatical form (all verbs, all nouns, all -ing forms, etc.).
Fix: "She likes hiking, to swim, and biking." (SAT)"She likes hiking, swimming, and biking." — all items must match form.
that vs which — restrictive vs nonrestrictive"that" introduces essential info with no comma; "which" introduces extra, nonessential info and needs a comma.
Fix: "The car, that I bought, is red." (SAT)Remove the commas and keep "that" (restrictive), or keep the commas and switch to "which."
Can you join an independent clause and a dependent clause with just a comma?Yes, when the dependent clause comes first or is a nonessential aside; a comma splice only applies to two independent clauses.
Fix: "Because it was raining. We stayed inside." (SAT)Fragment — join with a comma: "Because it was raining, we stayed inside."
What is a sentence fragment?A group of words punctuated as a sentence but missing an independent clause.
Fix: "The museum, which opened in 1990 has free admission on Sundays." (SAT)Add a comma after "1990" — the nonrestrictive clause needs commas on both sides.
Can a colon follow a dependent clause or sentence fragment?No — a colon must always follow a complete independent clause.
Fix: "My favorite subjects are: math, science, and art." (SAT)Remove the colon — "My favorite subjects are" is not a complete independent clause without the list.
Fix: "There going to their, house over there.""They're going to their house over there."
When can a semicolon separate items in a list?When the list items themselves contain commas — e.g., "I visited Paris, France; Rome, Italy; and Cairo, Egypt."
Can you use a comma before a restrictive "which" clause?No — restrictive clauses never take a comma; only nonrestrictive "which" clauses do.
Fix: "The report, that was released yesterday, sparked debate." (SAT)Remove the commas and keep "that": "The report that was released yesterday sparked debate."
What punctuation can introduce a supplement mid-sentence, and what's the rule?Commas, dashes, or parentheses — the pair must match (both commas, both dashes, or both parentheses).
Fix: "Every one of the players are required to attend." (SAT)"is" — "Every one" is singular; "of the players" is a prepositional phrase, not the subject.
What is the verb tense consistency rule?Keep verb tense consistent within a sentence or passage unless a time cue signals a shift.
Fix: "She was studying for hours and then goes to bed." (SAT)"went" — keep past tense consistent throughout.
Fix: "Neither of the answers were correct." (SAT)"was" — "neither" is singular.
How does a dash differ from a semicolon when joining two independent clauses?Both work like a period grammatically; a dash also signals emphasis or explanation, while a semicolon is neutral.
