The response addresses the question with a clear negative position, develops relevant main ideas about rural decline and urban strain, and briefly acknowledges benefits, though support is sometimes repetitive and underdeveloped.

Ideas are organised into clear paragraphs with a logical progression, but linking is often mechanical or faulty, with expressions like 'thats why' and some repetition of the same economic point.

Vocabulary is adequate for the task with some appropriate items such as 'urban infrastructure' and 'standard of living', but errors like 'loosing', 'weeks' for 'weakens', and imprecise phrasing limit precision.

A mix of simple and complex structures is attempted, but frequent errors in subject-verb agreement, pronoun use, and article choice repeatedly reduce accuracy although the meaning remains mostly recoverable.

The response presents a consistent negative judgement, develops rural and urban consequences and acknowledges economic benefits. Some support is overgeneralised: only old people stay, nobody wants to farm, and all residents suffer are asserted without qualification or examples.

Ideas progress logically across clearly focused paragraphs, with a range of cohesive devices used naturally and referencing generally clear throughout.

Vocabulary is adequate and appropriately used for the topic, with some less common items like informal settlements and agricultural land, but range is somewhat limited and repetition of simple phrasing reduces precision.

Sentences are generally accurate and include relative clauses, time clauses, concessions and coordinated cause-and-effect structures. Repeated coordination and cause-and-effect patterns limit flexibility despite this useful range.

The essay states a clear position throughout, addresses both benefits and drawbacks, and develops main ideas with examples, though the argument against urbanization sometimes drifts toward lifestyle preferences rather than the effects of rural population decline itself.

Paragraphing is logical with a clear acknowledge-then-rebut structure, and ideas progress coherently, though some transitions and pronoun references are slightly mechanical.

Vocabulary is sufficiently flexible and largely precise, including natural collocations such as positive feedback loop, gainful employment, and outlying districts, with only minor awkwardness in phrases like greater diversity in terms of where residents lived.

A wide range of complex structures is used with good control, including conditionals, relative clauses, and concession, and errors are rare and non-impeding.

The response presents a clear position throughout, addresses the question directly, and develops both sides with relevant supporting examples, though some ideas like the children's point receive limited extension.

Paragraphing is logical and cohesive devices are used appropriately to guide the reader, with only occasional mechanical sequencing such as 'Firstly... Besides... Thirdly'.

There is a reasonably wide vocabulary range including topic-appropriate terms like 'marginalization' and 'disposable income', but imprecise word choices and unnatural collocations recur and slightly impede clarity at times.

A variety of complex structures is produced with reasonable accuracy, yet errors in agreement, comparative forms, and relative clauses are noticeable and occasionally reduce clarity.

The response presents a clear position throughout, addresses all parts of the task, and develops main ideas with relevant if somewhat generalized examples.

Ideas progress logically across clearly structured paragraphs with a range of cohesive devices used naturally, though paragraph content follows a predictable pattern.

Vocabulary is precise and flexible, including items like 'close-knit community', 'social cohesion', and 'land degradation', with only minimal awkwardness.

A wide range of complex structures is used with flexibility and generally good control, with only occasional minor slips in phrasing.

The response addresses both sides of the migration question with relevant, developed ideas, but the final position that the effects are 'more or less balanced' is qualified and indirect, so the task is addressed thoroughly rather than with a fully clear stance.

Ideas progress logically through clear paragraphing, with effective linking devices such as 'On the other hand', 'Meanwhile', and 'In conclusion' supporting a coherent overall progression.

Vocabulary is sufficiently flexible and precise, with natural collocations like 'standards of living', 'responsible agriculture', and 'governable societies', despite occasional slips such as 'father' for 'further'.

A wide range of complex structures is used with generally good control, including relative and conditional clauses, and errors are minor and non-impeding.

The response directly answers the question with a clear, consistent position, addresses both sides, and develops main ideas with relevant, concrete examples and explanations.

Ideas progress logically across well-structured paragraphs with a range of cohesive devices and clear referencing, requiring no effort from the reader.

A wide and precise vocabulary is used flexibly and naturally, including topic-specific items such as 'human capital', 'rural exodus', and 'agricultural modernization', with only rare minor imprecision.

A broad range of complex structures is used with strong control, including effective concession clauses and subordination, with only rare, minor slips that do not affect communication.

The response directly answers the question with a clear, sustained position, develops two relevant main ideas with concrete supporting examples, and draws a consistent conclusion.

Ideas are organised logically across clear paragraphs with effective progression, though cohesion relies on somewhat mechanical linking phrases such as 'For instance' and 'Another significant benefit'.

Vocabulary is flexible and generally precise for the topic, using appropriate collocations like 'upward social mobility' and 'economic hubs', with only a modest, somewhat conventional range limiting a higher award.

A wide range of grammatical structures, including complex relative and conditional-like constructions, is used with flexibility and accuracy, with errors that are rare and non-impeding.
