How could the sentence 'Without help I would not finish this assignment.' be made clearer?

Adding a comma after "help" in the sentence 'Without help, I would not finish this assignment.' clarifies the structure and meaning of the sentence. The introductory phrase "Without help" sets the context for the rest of the sentence. By inserting a comma after "help," it emphasizes that the main clause begins immediately after, making it easier for the reader to understand the relationship between the absence of help and the inability to finish the assignment. This improves the overall readability and flow, ensuring that the reader can quickly grasp the condition being posed.

The other options do not have the same effect on clarity. A comma after "I would not" disrupts the flow of the main clause unnecessarily, while a comma after "not" does not create a natural pause or separation that enhances understanding. Similarly, adding a comma after "finish" would incorrectly separate the action from its object, potentially confusing the sentence structure.
