Which national roads connect the following South African cities and countries: a) Pietermaritzburg and Durban, b) Johannesburg and Pretoria, c) Nelspruit and Johannesburg, d) Kimberley and Port Elizab

I cannot answer questions 1, 2, or 3 with the provided image.

• Question 1 asks about national roads connecting various South African cities and countries. The provided map, Map 18, shows only the Western Cape province. Most of the cities and countries mentioned in Question 1 (e.g., Pietermaritzburg, Durban, Johannesburg, Pretoria, Botswana, Lesotho, Nelspruit, Kimberley, Port Elizabeth) are outside the scope of this Western Cape map, or the full routes cannot be determined from it. Therefore, I cannot accurately answer Question 1 using Map 18. My previous attempt to answer Question 1 was incorrect as it did not adhere to the constraint of using the provided map.
• Question 2 explicitly states "Using Map 10". Map 10 is not provided in the image.
• Question 3 explicitly states "Using Map 11". Map 11 is not provided in the image.
