Concept:The meridian that roughly divides Africa into two equal halves, east and west, is around $20^\circ\text{E}$ longitude.Explanation:Africa extends from about $17^\circ\text{W}$ in the west to about $51^\circ\text{E}$ in the east.The central or bisecting longitude is approximately $\frac{17^\circ\text{W} + 51^\circ\text{E}}{2} \approx 17^\circ\text{E}$.Among the given options, the longitude closest to this central position is $20^\circ\text{E}$.This meridian passes through Europe and Africa, making it the best answer.Answer:B. $20^\circ\text{E}$
