Question

(A) \(\quad\) NO CHANGE (B) It takes a lot to melt me my nature is quite unreactive. (C) It takes a lot to melt me: while my nature is quite unreactive. (D) It takes a lot to melt me; my nature is quite unreactive.

Short answer

Option D is correct; it uses a semicolon to connect two independent but related clauses.

Step-by-step solution

Identify the Components

First, identify the main components of the exercise. There are two independent clauses: 'It takes a lot to melt me' and 'my nature is quite unreactive.' Both clauses can stand alone as sentences.

Analyze the Options

Analyze how each option connects these two independent clauses: - Option A keeps them separate as currently presented (no change). - Option B combines them without punctuation, which is incorrect. - Option C uses a colon incorrectly, as the second clause doesn't explain or list something from the first clause. - Option D uses a semicolon to connect the two related independent clauses.

Select the Correct Option

The correct option uses appropriate punctuation to connect the two clauses. Since the clauses are closely related but could stand alone, a semicolon is appropriate. Therefore, Option D is the correct choice.

Key concepts

Understanding Independent Clauses

An independent clause is a group of words that can stand alone as a complete sentence. It contains a subject and a verb, forming a complete thought. For instance, in the sentence ‘It takes a lot to melt me,’ we see a subject ('It') and a verb ('takes'), making it an independent clause. Similarly, 'My nature is quite unreactive' also contains a subject ('My nature') and a verb ('is'), qualifying it as another independent clause. When you spot two independent clauses, they can either form their own individual sentences, or be connected using appropriate punctuation, such as a semicolon. This understanding is crucial for mastering PSAT grammar rules, making your writing clear and correct.

Mastering Punctuation in Sentences

Punctuation marks are essential tools in writing. They help clarify sentences and convey your meaning effectively. Common punctuation marks include periods, commas, semicolons, and colons.

• Periods (.) mark the end of a sentence.
• Commas (,) often separate items in a list or clauses within a sentence.
• Semicolons (;) connect closely related independent clauses.
• Colons (:) introduce lists or explanations.

Proper punctuation ensures that your writing flows well and prevents confusion. In our exercise, understanding how to correctly employ semicolons and avoiding incorrect usage of other punctuation is key to solving the problem.

The Importance of Semicolon Usage

Semicolons act as a strong glue between two separate thoughts, connecting independent clauses without using a conjunction like 'and' or 'but.' This punctuation mark acknowledges the relationship between the two clauses, while maintaining their independence. For example, in 'It takes a lot to melt me; my nature is quite unreactive,' the semicolon effectively connects two ideas that are closely related without needing a conjunction. Each clause could stand alone, but the semicolon elegantly ties them together, highlighting their relationship.

Understanding Sentence Structure

Sentence structure refers to how words and phrases are arranged to create clear and effective sentences. Every well-structured sentence features a subject and a verb, and often includes objects, complements, and modifiers. There are four main types of sentence structures:

• Simple Sentences - contain just one independent clause.
• Compound Sentences - connect two or more independent clauses, usually with a conjunction or semicolon.
• Complex Sentences - contain one independent clause and at least one dependent clause.
• Compound-Complex Sentences - mix multiple independent clauses with at least one dependent clause.

In our sentence example, using a semicolon transforms the two independent clauses into a cohesive compound sentence while respecting the independence of each idea. This structure not only complies with grammar rules but also improves readability and clarity.
