The correct option for the items used for exchange in Nigeria before money was introduced is
A. cowries, iron rods, brass rods, and copper rods.
Explanation of the Correct Answer
-
Historical Context: Before the introduction of formal currency, various items were used as mediums of exchange in different cultures. In Nigeria, particularly, cowries were one of the most widely recognized forms of currency. They were small shells that were easy to carry and had intrinsic value due to their rarity and beauty.
-
Items Used for Exchange:
- Cowries: These were the most common form of currency in Nigeria and many other parts of Africa. They were used for trade and as a measure of wealth.
- Iron Rods: These were also used as a form of currency, especially in trade among certain communities. They had value due to their utility and the labor involved in producing them.
- Brass Rods: Similar to iron rods, brass rods were valued for their material and were used in trade.
- Copper Rods: These were also used in trade and had value due to their metal content.
Why the Other Options are Incorrect or Weaker
-
Option B: Iron rods, copper rods, manilla, and cowries: While this option includes cowries and iron rods, it incorrectly lists "manilla." Manilla is a type of bracelet or armlet that was used in trade, but it was not as widely recognized or used as cowries in Nigeria. Therefore, this option is not as comprehensive as option A.
-
Option C: Cowries, manilla, brass rod, and copper wires: This option includes cowries and brass rods, but it incorrectly lists "copper wires." Copper wires were not a common medium of exchange in traditional Nigerian trade. Instead, copper rods were used. Additionally, the inclusion of "manilla" again detracts from the accuracy of this option.
-
Option D: Copper wires, brass wires, cowries, and iron rod: This option is incorrect because it mentions "copper wires" and "brass wires," which were not used as currency in the traditional sense. The correct forms were rods, not wires, and the inclusion of these terms makes this option less accurate.
