Debate on geography question with no 'correct answer'?

The opinion that question 79, code 324, geography subject in the social science exam of the 2023 high school graduation exam does not have the correct answer gives the following reasons: "Structure is the internal structure, or the proportions and relationships between the constituent parts, combined to create a system. Therefore, to draw a chart showing the change in the structure of objects, we must draw a chart of area; specifically in this case, a domain or circle chart; it is not possible to draw a column chart or a line chart to show the change in the structure of the volume of goods.

It is worth mentioning that with 4-year data, people never draw pie charts because it is difficult to see, difficult to compare objects... That is why only area charts are suitable, only when forced to do so, do people draw pie charts.

Question 79 of geography is causing controversy.

However, in my opinion, this is actually a good question based on basic knowledge of chart skills in geography and clearly differentiates candidates. But this question can cause confusion for candidates when doing the test.

In terms of geography, structure can be understood as a whole consisting of constituent components, expressed by the proportion (ratio) of each component in it. Structural shift is the change in the proportion of the components that make up the structure.

To show the structure as well as the change in structure of geographical phenomena through charts, it is usually possible to express it by basic chart types such as pie charts, column charts and area charts. In which, the column chart showing the structure is a column chart with a total of 100% at each point in time (different from the column chart showing absolute value). And of course, it cannot be expressed by a line chart because the line chart does not show the structure of the phenomenon.

Therefore, for question number 79, exam code 324 requires "appropriate chart types" to show the change in the structure of air cargo volume in our country, it can be expressed in the following chart types: circle, column and area. Therefore, the answer to this question is C.

In this case, with this question, if the exam requires choosing the most suitable chart to show the structural change, the correct chart is the area chart, due to the structural change (shift) over many years (4 years or more).

Here, it should be emphasized that the exam only requires determining the appropriate (not the most appropriate) chart types to represent structural changes, so pie, column and area charts are all acceptable.

Therefore, question number 79, exam code 324 of the 2023 high school graduation exam is not wrong, it is not "there is no correct answer".
