The answer is a)<span> Trade is a recent development in coastal countries.
</span>
This is an incorrect statement as Trade in the coastal countries of Africa goes back more than a millennium.
During the European colonialism, these countries experienced huge trade growth due to the slave trade and exploitation of natural resources.
Most of these countries had major ports which were used as trading posts, stop-overs and major entry points of West Africa.
After the expansion of the Spanish Empire in South America, trade between the two continents flourished and as late as the 19th and 20th century, European powers were still exploiting natural resources in the region.
Today, the region is growing thanks to billions of dollars of investment from China.

I think the answer is c but its between a and c
Answer:
3758 kJ
Explanation:
Given:
Mass of the ice = 10 kg = 10 × 1000 = 10,000 g
Initial temperature of the ice = -20° C
Now,
The ice will start to melt when it will reach a temperature of 0° C
and, specific heat of ice, C = 2090 J/kg
Therefore,
Heat required to heat the ice from -20° C to 0° C
Q₁ = mCΔT
or
Q₁ = 10 × 2090 × (0 - (-20 ))
or
Q₁ = 418000 J
also,
Heat of fusion required to change the ice into liquid without any change in temperature.
For ice the heat of fusion = 334 J/g
Hence,
Energy needed by ice to melt, Q₂ = 334 × 10,000 J = 3,340,000 J
Hence, the total heat required = Q₁ + Q₂
= 418000 J + 3,340,000 J
= 3758000 J
= 3758 kJ
Answer:
The answer would be B. If the developing countries use more natural resources then that adds to not only developED but also developING using more so they get used faster.
