Which of the following is the best version of the underlined portion of sentence 4 (reproduced below)? 'In a study conducted...'

Rationale

In a study conducted by researchers.

This version is the most descriptive and grammatically correct, clearly attributing the study to the researchers while maintaining proper sentence structure. It provides clarity and context, ensuring that the reader understands who conducted the study.

A (In a study conducted by researchers) CORRECT

This choice explicitly indicates that the study was carried out by researchers, making it clear and precise. The phrase “In a study conducted by researchers” serves as an effective introductory clause, setting the stage for the information that follows.

B (A study conducted) YOUR ANSWER

This option lacks clarity as it does not specify who conducted the study, leaving the reader without important contextual information. Moreover, it reads awkwardly as a standalone phrase, failing to integrate smoothly into the larger sentence.

C (Study conducted by the researchers) YOUR ANSWER

While this choice identifies the "researchers," it omits the article "A" or "The" at the beginning, which is necessary for proper grammatical structure. The absence of a determiner makes the phrase sound incomplete and less formal.

D (The study which was conducted by researchers) YOUR ANSWER

Though this option conveys the intended meaning, it is more wordy than necessary. The phrase "which was conducted" can be simplified to "conducted," making this choice less efficient and less direct.

Conclusion

Choosing the best version of the underlined portion relies on clarity, grammatical correctness, and conciseness. Option A effectively introduces the study by clearly attributing it to the researchers, ensuring the reader comprehends the source of the information. In contrast, the other options either lack clarity, are awkward, or are unnecessarily verbose, making them less effective choices.
