Final answer:
The sentence contains an error in tense due to the shift from present to future tense. Aligning the tenses for consistency would correct the error, ensuring clarity in the research design description.
Step-by-step explanation:
The sentence "The research design of this project is a content analysis as I will be coding the moral themes in romantic comedies." is mostly correct, but there is a subtle error in tense. The verb phrase 'is a content analysis' is in the present tense, but 'I will be coding' shifts to the future tense. To maintain consistency in tense, it would be better to align the tenses of the sentence. One possible correction could be: "The research design of this project is a content analysis, which involves coding the moral themes in romantic comedies." This revision keeps the present tense consistent throughout the sentence.
It is important to always check for subject-verb consistency and maintain the correct sentence structure to ensure clarity and coherence in academic writing. The sentence, as it stands, does not display an error in subject-verb agreement, an error in punctuation, or any issues with comma splices or unnecessary passive voice.
