Task Achievement / Task Response — Band 4.5

The response attempts to describe the seven stages of rain-shadow desert formation shown in the diagram, beginning with winds approaching the coast and ending with inland dry winds. However, the expression is severely confused and garbled throughout, such as in the opening sentence 'The diagram outline the stages of a forsake how it is rain formed for thousand kilometres.' While the main components (sea, coast, windward side, mountain, leeward side, and inland) are mentioned, the lack of clarity and frequent inaccuracies in describing the physical mechanisms (e.g., 'prevent rain shadow desert') mean that the information is only partially and confusingly communicated. This places the response in the lower bands for task fulfillment.

Coherence and Cohesion — Band 4.0

The text is divided into short paragraphs, but the overall organization lacks logical progression and clarity. Cohesive devices are used awkwardly or incorrectly, such as 'Overall ,this have seven stage of procedure .' and 'At the next stage ,the black clouds turn into rain...'. The referencing is frequently unclear, making it difficult for the reader to follow the sequence of the natural process being described. Paragraphing is attempted, but internal cohesion is weak and mechanical, preventing the text from achieving a smooth flow.

Lexical Resource — Band 4.0

The vocabulary used is extremely limited, repetitive, and frequently incorrect. Words are misused or distorted beyond standard usage, such as 'forsake' instead of process or formation, 'address' instead of approach, and 'acending' instead of ascending. There are severe spelling and word-choice errors throughout the text, such as 'happend', 'skyward', and 'leeward'. While some topic-related vocabulary appears ('clouds', 'rain', 'mountain'), the overall lexical control is insufficient to maintain clear communication.

Grammatical Range and Accuracy — Band 4.0

The response displays a very limited range of grammatical structures, and almost every sentence contains major grammatical errors. There are frequent issues with subject-verb agreement ('this have seven stage'), tense usage ('it happend rain'), missing prepositions, and faulty sentence construction ('This process is form on the top side of the desert'). Complex sentence attempts are heavily flawed and frequently result in distorted or incomprehensible meanings. Punctuation is also erratic, with spaces placed incorrectly before commas.
