Band 5+: The table below shows daily oil production in 4 countries from 2000 to 2004. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The report adequately covers the main features of the table, highlighting the overall trends for each country. It correctly identifies Congo as the highest producer and Chad as the lowest, and it notes the general increases for Somalia and Chad and the decrease for Congo. However, there are some inaccuracies and omissions: the report states that Chad produced the least from 2000 to 2004, but Chad had no production until 2003, and Somalia had higher production than Chad in 2003. Additionally, the report incorrectly states that Chad had no data until 2002, when it had no production until 2003. The report also omits the specific figures for Nigeria's production in 2000 and 2001, and it does not mention the exact values for Somalia's production in 2001 and 2002. To improve, ensure all key data points are accurately reported and that comparisons are precise. The overall structure is logical, but the language could be more formal and precise.

The report has a logical structure with an introduction, overview, and body paragraphs, but the flow is disrupted by unclear referencing and abrupt transitions. For example, the phrase 'it is clear that' is used but the comparison is not fully developed. The paragraphing is acceptable, but the use of cohesive devices is limited and sometimes inaccurate (e.g., 'in between' instead of 'between', 'there so no data' instead of 'there was no data'). To improve, use a wider range of linking words and ensure each paragraph has a clear central idea with smooth connections between sentences.

The vocabulary is adequate for the task but lacks variety and precision. There are repetitions (e.g., 'produce', 'rise') and some awkward phrasing (e.g., 'how many numbers of barrels', 'the highest number of barrels of oil production country'). The report would benefit from using more specific and varied vocabulary, such as 'output', 'production levels', 'experienced a decline', 'saw a significant increase', and 'remained stable'. Also, ensure correct word forms (e.g., 'produced' instead of 'produce' when referring to past events). Boost vocabulary complexity to elevate the overall score.

The report contains numerous grammatical errors that affect clarity, including subject-verb agreement ('it produce', 'it rise'), incorrect prepositions ('in between', 'at the and of'), and missing articles ('the least number from 2000 to 2004' should be 'the least number from 2000 to 2004' but also 'the lowest production'). There are also issues with tense consistency and sentence structure. To improve, focus on using past tense consistently, correcting subject-verb agreement, and using a variety of complex structures (e.g., relative clauses, passive voice) with accurate punctuation.
