4. the average precipitation in lagos is about the same as the average precipitation in the other four cities combined.
5. people in all five cities are able to grow crops outdoors in winter.

Explanation:

1. Check Cairo's precipitation (20 inches, low).
2. Calculate Cape Town's high temp difference: $78 - 63 = 15$.
3. Find low temp differences: Cairo ($65-47=18$), Cape Town ($60-45=15$), Lagos ($83-74=9$), Nairobi ($69-51=18$), Tripoli ($85-71=14$). Lagos has the smallest difference.
4. Sum other cities' precipitation: $20+72+15+10=117$. Lagos has 37 inches, not equal.
5. Cape Town's growing season is 8-12 months, not full winter guarantee.
