The map below shows Zimbabwe and its neighbouring countries. A map of Zimbabwe and neighbouring countries. Use information above to answer the questions that follow.

The river on the border line of South Africa and Zimbabwe is the $\boxed{\mathbf{Limpopo \text{ River}}}$.

The Zambezi River forms a border between Namibia and Zambia, and between Botswana and Zambia. It does not form a direct border between Botswana and Namibia.

Since the Zambezi River does not form a border between Botswana and Namibia, the probability is $0\%$.
The probability is $\boxed{\mathbf{0\%}}$.

Victoria Falls is to the north-west of Kruger National Park.
The compass direction is $\boxed{\mathbf{North-West}}$.

The claimed scale is $1 : 5 000 000$. This means $1 \text{ unit}$ on the map represents $5 000 000 \text{ units}$ in reality.

$1 \text{ cm}$ on the map represents $5 000 000 \text{ cm}$ in reality.
Convert $5 000 000 \text{ cm}$ to kilometers:

So, according to the claimed scale, $1 \text{ cm}$ on the map represents $50 \text{ km}$ in reality.

If $1 \text{ cm}$ represents $50 \text{ km}$, then $125 \text{ km}$ would be represented by:

By visually inspecting the map, the bar scale segment labeled "$125 \text{ km}$" measures approximately $2.5 \text{ cm}$.

Since the calculated map length for $125 \text{ km}$ ($2.5 \text{ cm}$) matches the visual length of the $125 \text{ km}$ bar scale on the map, the claim is $\boxed{\mathbf{VALID}}$.
