Final answer:
The incorrect pronoun 'you' should be replaced with 'they' to match the subject 'Pilots'. It is crucial to know the difference between subject personal pronouns and object personal pronouns for correct usage. When proofreading, one should double check the words suggested by spell check applications.
Step-by-step explanation:
The incorrect pronoun in the sentence provided is 'you'. The correct pronoun should maintain consistency with the subject 'Pilots', which is a third person plural noun. Therefore, the sentence should use a corresponding third person plural pronoun 'they' to match the subject. The corrected sentence should read: "Pilots should carefully check every control in the cockpit before they request permission for takeoff."
It's essential to know the difference between subject personal pronouns and object personal pronouns to use them correctly. Subject personal pronouns (I, you, he, she, it, we, they) act as the subject of a sentence, while object personal pronouns (me, you, him, her, it, us, them) receive the action of the verb.
Additionally, when proofreading your work, it's advised to double check the words suggested by spell check applications, as they may not always provide the correct suggestions. Avoiding spelling errors is important to ensure the clarity and professionalism of your writing.
