The subject "research team" is a singular collective noun requiring the singular verb form "has concluded." Don't be confused by the intervening clause "which has been studying climate patterns for over a decade"—the main subject remains singular. Subject-verb agreement requires matching singular subjects with singular verbs.
"Each" is always singular, even when followed by a prepositional phrase containing plural nouns like "of the students." The singular subject "each" requires the singular verb "is." This is a common SAT trap—test makers place plural words between the subject and verb to distract from the true subject-verb relationship.
The sentence requires a simple past tense verb "received" to match the time frame "during her lifetime." The subject "novelist Virginia Woolf" is singular, and the action occurred in the past. Choice A lacks a complete verb form, while C uses incorrect plural form and D uses present tense inappropriately.
"For example" is the most logical transition because the second sentence provides a specific example supporting the general claim in the first sentence. The Mayan calendar system exemplifies how ancient civilizations developed sophisticated mathematical systems for tracking celestial movements. Transitions like "however" or "in contrast" would incorrectly suggest opposition rather than supporting evidence.
After a semicolon, the second independent clause should explain or provide specifics about the first clause's general statement. "Specifically" correctly introduces details about how the committee members disagreed. The semicolon joins two complete sentences with closely related ideas, and "specifically" shows the second part elaborates on the disagreement mentioned first.
The phrase "the first woman to win a Nobel Prize and the only person to win Nobel Prizes in two different sciences" is a nonessential descriptive clause providing additional information about Marie Curie. Such clauses must be set off with commas on both sides. The comma after "sciences" matches the comma after "Curie" that begins the nonessential information, properly bracketing the description.
A colon is correct here because it introduces a list or explanation of what artifacts were discovered. The structure is: complete sentence + colon + list or explanation. The colon signals "here's what I mean" and introduces specific examples of the artifacts mentioned generally in the first clause. Colons are frequently tested on the SAT for introducing lists and explanations.
In "neither...nor" constructions, the verb agrees with the noun closest to it. Since "teachers" (plural) is closer to the verb than "principal" (singular), the verb must be plural: "were." This rule applies to both "neither...nor" and "either...or" constructions—always match the verb to the closest subject.
The phrase "many of which date back to the medieval period" is a nonessential relative clause providing additional information about the manuscripts. It should be set off with commas because the sentence would still be complete without this information. The comma after "period" closes the nonessential clause that began after "manuscripts," creating proper punctuation boundaries.
The pronoun must agree with its antecedent "sharks," which is plural. "They are" correctly refers back to the plural noun "sharks" mentioned in the dependent clause. Pronoun-antecedent agreement requires matching plural pronouns with plural nouns and singular pronouns with singular nouns—a fundamental grammar rule frequently tested on the SAT.
The subject "insights" is plural, requiring the plural verb "have." The sentence uses present perfect tense ("have transformed") to indicate an action that began in the past and continues to affect the present. Don't be distracted by "economist's theory" earlier in the sentence—the subject of this clause is clearly "insights," which is plural.
No punctuation is needed after "daily" because the sentence continues with a parallel participial phrase "studying with master teachers." The structure uses two parallel elements: "practicing for hours daily" and "studying with master teachers," both modifying how she spent years perfecting her technique. Adding punctuation would incorrectly separate parallel elements that should flow together.
A semicolon is correct because it joins two independent clauses that are closely related in meaning. Both clauses can stand alone as complete sentences: "The research findings were surprising" and "they suggested that previous assumptions were completely incorrect." Semicolons are one of the most frequently tested punctuation marks on the SAT because they have clear, specific rules for proper usage.
A comma is needed after "talent" to close the nonessential phrase "combined with her natural talent" that began with the comma after "training." This parenthetical phrase provides additional information but could be removed without destroying the sentence's basic structure: "The athlete's dedication to training enabled her to achieve success." Nonessential phrases must be enclosed by commas on both sides.
"Its" (possessive pronoun without an apostrophe) correctly shows that the methodology belongs to the research team. "It's" is a contraction meaning "it is," which doesn't fit the context. While "their" is grammatically acceptable for a collective noun like "team," the singular "its" is more precise when referring to the team as a single unit. This distinction between "its" (possessive) and "it's" (contraction) is frequently tested on the SAT.

Achieving mastery in SAT grammar requires understanding fundamental rules and practicing their application in test-like contexts. The digital SAT Reading and Writing section tests grammar through 26-28 questions (approximately half the section), making grammar proficiency essential for strong overall scores.
Essential Grammar Study Strategies
Effective SAT grammar preparation combines systematic rule learning with extensive practice. Focus your study on high-frequency concepts that appear repeatedly on the test, including subject-verb agreement, pronoun usage, punctuation, and sentence boundaries. These core concepts account for the majority of grammar questions.
Systematic Grammar Improvement Plan:
- Learn rules explicitly: Understand the grammatical principles behind correct answers rather than relying on "what sounds right"
- Practice with official materials: Use College Board practice tests to familiarize yourself with actual SAT question formats
- Analyze mistakes systematically: When you answer incorrectly, identify which grammar rule you misapplied and review that concept
- Take timed practice: Build speed by practicing under realistic time constraints—approximately 60 seconds per question
- Review explanations thoroughly: Read explanations for both correct and incorrect answers to deepen understanding
Common Grammar Traps to Avoid
The SAT strategically constructs questions to test whether you truly understand grammar rules or simply rely on intuition. Test makers insert distractors that "sound correct" but violate specific rules, particularly in subject-verb agreement questions where prepositional phrases separate subjects from verbs.
Train yourself to identify grammatical subjects by crossing out prepositional phrases and focusing on core sentence structure. This technique helps you match subjects with verbs accurately even when distracting words appear between them. Similarly, for pronoun questions, always identify the specific antecedent and verify number agreement explicitly.
Punctuation Mastery
SAT punctuation questions test whether you understand how commas, semicolons, colons, and dashes function to separate and connect ideas. Master these rules systematically: semicolons join independent clauses, colons introduce lists or explanations, commas set off nonessential information, and dashes emphasize parenthetical material.
When facing punctuation questions, first determine whether you're dealing with independent clauses (complete sentences) or dependent clauses (fragments). This distinction determines which punctuation marks are grammatically acceptable. Remember that you can only join two independent clauses with semicolons, periods, or commas plus coordinating conjunctions—never with commas alone, which creates run-on sentences.
