SAT Grammar Rules and Practice Tests 

'In writing, clarity often depends on sentence structure. A well-structured sentence places the subject close to the verb to avoid confusion. When the subject and verb are separated by too many phrases or clauses, readers may struggle to understand the main idea. For example, “The book that she bought yesterday is on the table” is clearer than “The book is on the table that she bought yesterday.” Improving sentence structure often involves rearranging words to make sentences more direct and easier to read. Writers should focus on simplicity and avoid unnecessary complexity to enhance clarity. What is the best way to improve sentence clarity based on the passage?'

“The class covered several difficult topics today; calculus limits, trigonometric identities, **and matrices that involve imaginary numbers.**” What is the best punctuation revision for the underlined portion of the sentence?

'Grammar rules help ensure effective communication. Using subject-verb agreement correctly is essential for grammatical accuracy. For example, “She walks” is correct, while “She walk” is not. Mistakes in grammar can confuse readers and weaken the writer’s credibility. Writers should also avoid common errors like incorrect pronoun case or inconsistent tense. By mastering grammar and usage, writers make their writing clearer and more professional. According to the passage, what is crucial for grammatical accuracy?'

However, writers should avoid run-on sentences by correctly punctuating and joining ideas. According to the passage, what helps combine two independent clauses?'

What does the passage suggest about maintaining parallelism in sentences?'

'Active voice makes writing clearer and more direct. In active voice, the subject performs the action: “The chef cooked the meal.” Passive voice places the subject as the receiver of the action: “The meal was cooked by the chef.” Active voice generally creates stronger, more engaging sentences.
