IELTS Writing Task 1 question

The charts below show the changes in ownership of electrical appliances and amount of time spent doing housework in households in one country between 1920 and 2019.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Percentage of households with electrical appliances (1920-2019)

Student answer (Band 7.5)

The line charts illustrate household appliance ownership rates alongside weekly time devoted to domestic chores in a single nation from 1920 to 2019.

Overall, the adoption of all three modern electrical appliances experienced significant growth over the century, which inversely corresponded with a drastic reduction in time spent on housework.

Appliance Ownership In 1920, vacuum cleaners were installed in 30% of homes, while washing machines were present in 40%, and refrigerators were virtually nonexistent at just over 2%. By 1980, refrigerator adoption reached complete market saturation (100%), where it remained through 2019. Vacuum cleaner usage followed a steady upward trajectory, eventually reaching 100% saturation by the year 2000. Conversely, while washing machine adoption increased to 70% in 1960, it experienced a minor drop in 1980 before gradually recovering to finish at around 75% in 2019.

​A sharp inverse relationship is evident in weekly domestic labor duration. In 1920, households allocated 50 hours per week to housework—defined as laundry, meal preparation, and cleaning. This figure declined continuously over subsequent decades, dropping steeply to 20 hours in 1960, before leveling off to hit an all-time low of approximately 10 hours per week by 2019.

AI examiner evaluation

Task Achievement / Task Response — Band 7.5

The response fully addresses all parts of the task by reporting the main features, making relevant comparisons, and presenting a clear overview of the data. The student successfully integrates information from both the appliance ownership chart and the housework hours chart. Key trends—such as the dramatic rise in refrigerators and vacuum cleaners to 100% saturation, the fluctuation in washing machine ownership, and the inverse relationship with the declining hours of housework—are accurately reported with precise figures. The data points cited match the visual reference very closely, and the overview effectively captures the broader relationship between the two datasets, meeting all criteria for a high band score.

Coherence and Cohesion — Band 7.5

The response is logically organized with a clear overall progression. It begins with a well-formulated introduction, followed by a concise and accurate overview paragraph. The body paragraphs are logically divided into appliance ownership and housework hours, aiding readability. Cohesive devices are used effectively and naturally without feeling mechanical, as seen in transitions like 'By 1980', 'Vacuum cleaner usage followed...', and 'Conversely'. Paragraphing is used sufficiently and appropriately to group related ideas, demonstrating strong control over structural cohesion throughout the text.

Lexical Resource — Band 7.5

The student demonstrates a wide, fluent, and flexible range of vocabulary appropriate for an academic task. Phrases such as 'appliance ownership rates', 'complete market saturation', 'steady upward trajectory', and 'inverse relationship' show skillful use of uncommon lexical items. Word choice and collocations are generally very precise, with only occasional minor imperfections. Spelling is flawless throughout the response, and the lexical range enables the writer to convey precise meanings smoothly and effectively.

Grammatical Range and Accuracy — Band 7.5

The writing exhibits a wide range of complex sentence structures used with a high degree of accuracy. The majority of sentences are error-free, and the student successfully employs participial phrases ('while washing machines were present in 40%, and refrigerators were virtually nonexistent...') and subordinate clauses. Punctuation is handled correctly to separate clauses and introduce lists. There are only very occasional minor structural awkwardnesses, but grammatical control is exceptionally strong overall, supporting clear and precise communication.
