Question 19

In a study conducted by researchers

This version provides a clear and complete reference to the study, indicating who conducted it while maintaining proper grammatical structure.

A) In a study conducted by researchers

This option is correct because it clearly identifies the subject of the study and attributes it to the researchers, providing essential context for the reader. It maintains a formal tone and integrates seamlessly into the sentence.

B) A study conducted

While this option conveys the idea of a study, it lacks specificity regarding who conducted the study. This omission makes it less informative and diminishes clarity, which is essential in academic writing.

C) Study conducted by the researchers

This choice is grammatically awkward as it lacks an article before "study," making it sound incomplete. Additionally, it does not indicate who conducted the study until after the noun, which can disrupt the flow of information.

D) The study which was conducted by researchers

Although this option provides context, it is unnecessarily wordy. The phrase "which was" adds extra words that could be streamlined for clarity and conciseness, making it less effective than the correct answer.

Conclusion

The correct answer, "In a study conducted by researchers," is the most effective because it is clear, specific, and grammatically correct. The other options either lack specificity, are awkwardly phrased, or introduce unnecessary complexity, making them less suitable for academic writing.
