The provided pie charts compare the international market of three computer operating system to others between 2012 and 2015

In general, it can be seen from the diagrams that the figure of OS 1 were the highest with the exception in 2012. Moreover, the percentage of other types of systems reduced significantly in 4-year period.

Firstly, the proportion of other systems account for 48 percent which is the highest in the 2012 while the OS 1, OS 2 and OS 3 only take up 20 percent, 17 percent and 15 percent, respectively. After witnessing a steady change in the next 2 years, both figure of OS 3 and other systems reduce especially the proportion of other fall twofold from 48 percent to 23 percent. Additionally, the rate of OS 1 and OS 2 increase but that of OS climb more dramatically than that of OS 2.

In addition, in the last year of 4-year period the rate of all types of computer systems witnessed a change. Particularly, the percentage of OS 1 and OS 3 both witnessed a slight increase by 5 percent and 3 percent, respectively. Meanwhile that of OS 2 continued to decrease by 8 percent beco

Task Response

The report attempts to address the task but suffers from significant issues with data accuracy and completeness. There is a major discrepancy between the report and the provided data; for example, the report claims 'other systems' accounted for 48% in 2012, whereas the data indicates OS 1 held that share. This leads to a fundamental misunderstanding of the trends. Additionally, the report is incomplete, ending mid-sentence. To improve, ensure that you carefully map the data points to the correct categories and complete your sentences to provide a full overview of the trends.

Coherence & Cohesion

The report suffers from significant issues with coherence and cohesion. The progression of ideas is difficult to follow, and the logical flow is interrupted by incomplete sentences (the report ends abruptly mid-word). While you attempt to use cohesive devices like 'In general', 'Firstly', and 'In addition', they are not always used effectively to link ideas. To improve, ensure that every paragraph has a clear central topic and that your sentences connect logically to form a complete narrative. Most importantly, always ensure your report is finished and does not cut off mid-sentence.

Lexical Resource

The vocabulary is limited and often used inaccurately. There are several instances where word choices do not fit the context (e.g., 'the figure of OS 1 were the highest', 'the rate of OS climb'). There is also a lack of variety in how you describe changes and proportions. To improve, work on learning collocations related to data description (e.g., 'accounted for', 'represented', 'experienced a decline') and ensure that the nouns and verbs you use agree in meaning and context.

Grammatical Range & Accuracy

Grammatical errors are frequent and often impede communication. There are issues with subject-verb agreement (e.g., 'the figure... were', 'the proportion... account'), article usage, and sentence structure. The report also contains incomplete thoughts and unfinished sentences. To improve, focus on mastering basic sentence structures, particularly subject-verb agreement and tense consistency. Practicing the use of complex sentences with subordinating conjunctions will also help increase your range, but only once accuracy in simple sentences is achieved.
