The writer has not indicated the type of graph that was provided for this report. Thus creating a difficult to reconstruct image for the reader. He is also confusing the reader by not completely mentioning all 6 countries in his trending outline. It would be best if he did not mention any countries at all and simply used a general reference to the highest and lowest points in the graph. Afterall, the trending statement does not need to contain any full or partial analysis at that point. It must only contain a measurement observation. One measurement observation is more than sufficient for that task.

The countries for reporting should be divided into 2 groups for the report. Grouping them by regional location or some other method would be more than acceptable for this task as it will offer additional and related information for the clarity of the reader. The groups should not contain more than 3 related countries per reporting paragraph.

The report for lower secondary school can be deemed to be under reported in this case as it does not reflect the other countries that were included in the measurement. This means that the report is under developed and analyzed. It will not allow the examiner to reward full points for that paragraph.

Thank you for your useful advice, I will try to complete my task more perfectly
