Living Alone or in Small Family Units in Cities

The response addresses both sides of the question and presents a clear, consistent position that the trend is mainly negative, with relevant main ideas, though some points receive limited development.

Ideas are logically organised into clear paragraphs with effective use of cohesive devices such as furthermore, however, and as a result, with only occasionally mechanical linking.

The response uses a sufficient range of topic-appropriate vocabulary, including nuclear families and vulnerable state, though expressions such as death cases and true to people show occasional collocational imprecision.

There is a good variety of complex structures, including relative and conditional clauses, with generally accurate control. Agreement with the collective noun family is interpretable, although singular agreement would clarify the household-as-unit reading.

The response maintains a clear position that the benefits and drawbacks are equally significant. The negative effects receive relevant support, but the housing paragraph explains pressure to form smaller households without establishing the promised economic benefit.

Ideas progress logically through a clear four-paragraph structure with effective sequencing devices, although a few cohesive links within paragraphs rely on loose causal connections.

There is a good range of natural topical vocabulary such as nuclear families, housing stock, squalid housing conditions, and ties of kinship, used with only minor awkwardness in phrasing.

A variety of complex structures, including conditionals and relative clauses, is used with flexibility and generally good accuracy, with only occasional errors that do not impede meaning.

The position is clear and consistently negative, with relevant discussion of independence and isolation. However, the Vietnam example does not establish the claimed link to living arrangements, and the generational comparison and coverage of small families need fuller support.

Paragraphing is logical with clear progression and appropriate connectors, though some linking within sentences is slightly mechanical.

Vocabulary is sufficiently flexible with attempts at less common items like 'advent' and 'the national economy', though occasional imprecise collocations appear.

A good range of complex structures is used with generally accurate control. Local errors include the article in a worse mental health and the awkward number choice in any other previous generations, but these do not prevent understanding.
