Question

(A) NO CHANGE (B) to go to Mars, however won't (C) to go to Mars but won't (D) to go to Mars, and, won't

Short answer

Option C is the correct choice.

Step-by-step solution

Understanding Sentence Structure

The sentence in the exercise appears to be a compound sentence where two independent clauses are typically joined by a conjunction. We must look for the correct conjunction and punctuation to maintain clarity and grammatical correctness.

Evaluating Option A

Option A suggests 'NO CHANGE'. This implies maintaining the existing punctuation and conjunction (if any). However, based on common English usage, we know 'NO CHANGE' isn't clarifying the relationship between action and consequence effectively.

Analyzing Conjunction Usage in Options

In Option B, a comma is used before 'however' which suggests a pause often used to indicate contrast but is incorrect as it's not directly joining two independent clauses. In Option D, 'and,' is used with both a comma before and after it inaccurately suggests both a pause and continuity, which disrupts the natural flow.

Reviewing Option C

Option C suggests using 'but' as a conjunction, which makes it clear that there are opposing outcomes — wanting to go to Mars but not going. This option properly uses 'but' to suggest contrast and doesn't use any unnecessary commas.

Verifying Grammar and Context

Upon reviewing the rules of punctuating compound sentences and the logical need for contrast between actions, we see that "to go to Mars but won't" correctly fulfills both the grammatical and contextual needs of the sentence.

Key concepts

Compound Sentences

A compound sentence is a sentence that contains at least two independent clauses. An independent clause is a group of words that can stand alone as a sentence because it presents a complete thought.

A compound sentence typically gives the reader more information by linking these independent clauses with a conjunction or a semicolon. This helps to show the relationship between two ideas or actions. For instance, in the context of wanting and not going to Mars, the use of a compound sentence conveys a cause-and-effect or contrast relation.

By understanding compound sentences, you improve your ability to convey complex ideas logically and clearly. This sentence formation technique not only enhances your writing but also aids in precise understanding during reading.

Conjunction Usage

Conjunctions are vital in connecting sentences or clauses to make language more fluid and comprehensive. They can express a variety of relationships, such as addition, contrast, or cause-and-effect.

• 'And' suggests addition, bringing together two related ideas.
• 'But' indicates contrast, which is perfect for showing opposing ideas, as illustrated in our Mars example.
• 'However' is typically used to indicate contrast too, but it is best for separating ideas not directly joined in a compound sentence.

In our exercise, 'but' was the optimal choice for expressing contrast without unnecessary complexity. This demonstrates the powerful role of conjunctions in crafting sentences that are both informative and clear.

Sentence Structure Analysis

Sentence structure analysis involves examining how different parts of a sentence relate to each other. This skill helps in identifying errors, such as misplaced commas or inappropriate conjunctions, that may obscure the intended meaning.

Our exercise's analysis showed how incorrect punctuation and conjunction choice can break the natural flow of a sentence. For example, using 'and,' disrupted continuity by inserting unnecessary pauses.

By learning to properly analyze sentence structure, you enhance your capability to write accurately and read critically. You'll be able to spot and fix common grammar mistakes, making your communication much more effective.
