Final answer:
The vague and potentially biased word in the thesis statement is "people." The statement can be revised to "All-girls schools should hire only qualified individuals regardless of gender," focusing on qualifications instead of specifying a gender.
Step-by-step explanation:
The vague word in the thesis statement "All-girls schools should hire only female people" is "people." This could be seen as reinforcing gender bias by unnecessarily specifying gender when the focus should be on the qualifications for the job. One way to rewrite the statement to avoid gender bias could be:
- All-girls schools should hire only qualified individuals regardless of gender.
This revision eliminates the gender specification, making it inclusive and non-discriminatory while emphasizing the qualifications over any gender.
