The cultural differences which made the adoption of Federation necessary in Nigeria include the following EXCEPT

Analyze the question: We are asked which option is NOT a cultural difference that made federalism necessary in Nigeria. This is an "EXCEPT" question, so we look for the odd one out.

Concept: Federalism was adopted in Nigeria (formally in 1954, building on the 1946 Richards Constitution and the 1951 Macpherson Constitution) because Nigeria is a very diverse country. The diversity that made a federal system suitable includes:

• Languages: Hausa, Yoruba, Igbo and hundreds of other languages
• Religion: Islam, Christianity and traditional religions
• Customs and traditions: different ways of life, marriage, chieftaincy and political systems
• Other factors such as size, ethnic diversity and fear of domination by larger groups

Step-by-step solution:

1. Customs (B): A cultural difference among Nigerian peoples. It is part of the list.
2. Languages (C): A major cultural difference. It is part of the list.
3. Religious (D): A cultural difference between the North, West and East. It is part of the list.
4. Traditions (E): A cultural difference. It is part of the list.
5. Colonial desire (A): This is not a cultural difference between Nigerian peoples. It refers to the wishes or motives of the British colonial administration, not to the native cultures of the people. So it does not belong with the others.

Answer: The option that is not a cultural difference is A. colonial desire.

Tip: In "EXCEPT" questions, group the options first. Here, four options (customs, languages, religion, traditions) are cultural features, while "colonial desire" is a political or administrative motive. The odd one out is usually the answer. For cultural diversity in Nigeria, think "CLRT": Customs, Languages, Religion, Traditions.
