Concept:The writer concludes that since English remains Nigeria's official language, everyone must agree on a standard pattern of correctness to ensure effective communication.
Explanation:The passage first describes the colonial era when fluency in English, especially with an Oxford accent, was highly prized.
Today, however, many teachers and graduates show poor command of English, while some Nigerians excuse themselves by saying they are not English people or did not specialise in English at the university.
Despite these excuses, the country has adopted English as its official language for instruction, parliamentary proceedings, and official business.
Since English will continue to be used, the writer stresses that it is imperative for all users to agree on the correct pattern of the language.
This agreement is essential for effective communication.
Option B is incorrect because the passage does not say fluency causes empty thoughts; it only says fluent speakers were sometimes empty of ideas.
Option C is incorrect because no hatred of English is mentioned as the reason Nigerians disown the language.
Option D is incorrect because the passage does not recommend that every undergraduate specialise in English.
Option A directly matches the author's final and main argument in the passage.
Answer:A. we need to agree on the pattern of correctness in the use of English language
