Final answer:
The incorrect sentence uses a plural pronoun with a singular subject, which violates standard English grammar rules pertaining to indefinite pronouns is - Option B. To avoid gender bias in writing, it is acceptable to use 'they' as a singular pronoun. For possessives, it is important to correctly place apostrophes to indicate ownership.
Step-by-step explanation:
To address the initial query, the sentence ‘Every worker in this office needs their own computer.’ is incorrect. This sentence incorrectly pairs the singular noun ‘every worker’ with the plural possessive pronoun ‘their.’ According to English grammar rules, singular indefinite pronouns require singular possessive pronouns. Therefore, the sentence should be ‘Every worker in this office needs his or her own computer.’
When it comes to avoiding gender bias in writing, strategies include rephrasing, using ‘they’ as a singular pronoun, or alternating between masculine and feminine pronouns in different sections. Rewriting sentence 1, ‘Each doctor will explain their own procedures.’ can eliminate gender bias. Sentence 2 can be rewritten as ‘When you call the technician, tell them the computer broke yesterday.’
