Analyze the question: This is a literature-in-English question on Jerry Agada's The Successes. It asks why the civil war created business opportunities for Owoicho.

Explain the concept: In the novel, Owoicho is a Nigerian who benefits from the post-war and wartime environment. Before the war, many Igbo (Ibo) traders and businesspeople dominated commerce in many Nigerian towns, including those in the North and Middle Belt. When the war broke out, many Igbo people left those places and returned to the East. Their businesses, shops, and trading positions were left empty.

Step-by-step solution:

1. Option A, "the Ibos were conscripted into the army": the novel does not present this as the reason for the opportunities. Conscription also does not explain why business gaps appeared in Owoicho's environment.
2. Option C, "the Ibos had ventured into other businesses": this does not explain why Owoicho gained opportunities.
3. Option D, "He became the supplier of all essential commodities": this is an overstatement. It describes something Owoicho did, not the reason the opportunity existed. The question asks why the opportunities arose.
4. Option B, "the exit of the Ibos created a vacuum": this fits best. When the Igbo traders left, a gap opened in the market, and people like Owoicho moved in to fill it.

Answer: B

Tip: In literature questions that ask "because...", look for the option that states the cause rather than the result. Here, the cause is the departure of the Igbo, which created the vacuum. Becoming a supplier (D) is the result of that opportunity.
