Two statements support the claim that Jenner has been given credit for starting and spreading the practice of immunization:
- Jenner became interested in the protective effects of cowpox during his apprenticeship. Here, we are told that Edward Jenner started working on ways to defend the body against diseases as early as during his apprenticeship when he was a teenager. He had been told that farm workers who had contracted cowpox were immune to the smallpox epidemic which was spreading across Europe at the time. He then started working on a vaccine containing cowpox.
- Jenner made the first step to erase smallpox. This first step was to try his new smallpox vaccine on a child in 1796. The child did not catch smallpox. In order to get recognition and validation from the authorities, Jenner administered his vaccine to 22 more people, with success.

The high plains are found in the northern part of Ghana.

The hilly Akwapim-Togo ranges are found along Ghana's eastern international border
The difference in elevation in meters between the points X and Y is 360.
Explanation:
On the presented map we can see that the relief is depicted with contour lines. The contour lines are marked with their elevations, or rather the main contour lines are, every fifth one. We also have the contour interval, which is 20 meters, thus giving us the basis so that we can find the difference in elevation between any points on the map.
What we know for sure from the map is:
- the elevation is increasing from southeast toward northwest
- the difference in elevation between the contour lines is 20 m
- the difference in elevation between the main contour lines is 100 m
Point X is marked on the contour line of 1,600 m. Point Y is marked on the second contour line between the 1,200 m and 1,300 m contour lines, thus:
2 x 20 = 40
So we have 1,240 m. Having the elevations of the two points, we only need to take the lower value from the larger value:
1,600 - 1,240 = 360 m
So we get a result of 360 m of difference in elevation between the points X and Y.

Most likely due to the movement of plate tectonics. They are plates of earth under the ocean that move occasionally, over the years this is probably what happened. Plate tectonics are also the cause of most earthquakes and even tsunamis. Erosion could also play a factor in this as well.
