Model Answer 1:
The first line graph outlines how the electrical appliance 
ownership in households in a country transformed during a 
century commencing from 1920 while the second chart delineates 
how it had affected the time spent on household work per week 
by the citizens in this country. 
As a general trend, with the increasing number of electrical 
devices possessed by families, their need for doing housework 
significantly declined.
As the graph reveals, only 30 percent of households in this 
country used to have vacuum cleaners and four out of ten 
families had washing machines in 1920. Refrigerators were a rare 
electric appliance at that time. Just after two decades, however, 
refrigerator possessions shoot up, and almost half of the families 
owned these three electric items in their homes. More families 
started to own such devices and at the beginning of the twenty-
first century, almost all households had fridges and vacuum 
cleaners. The washing machine was owned by more than 70% of 
families which slowly but steadily increased till 2019. At that 
point, there was hardly any family without a refrigerator or 
vacuum cleaner. 
It is interesting to note that, with the increasing number of 
electric appliances owned by families, their need for doing 
household work like preparing meals, cleaning and washing 
clothes remarkably diminished. While they used to work for 50 
hours a week doing such work in 1920, it decreased to 20 hours 
in 1960 and 10 in 2019.

Model Answer 2:
The line graphs show data on the ownership of household devices 
and the duration of housework done by families in a country 
between 1920 and 2019. 
Overall, the possession of household machines had significantly 
increased since 1930, with refrigerators and vacuum cleaners 
being owned by every family. As a result, the amount of 
housework needed to be done by people declined 
proportionately. 
According to the first graph, refrigerators were a rare commodity 
in houses in 1920, but their presence soared afterwards. Since 
1980, every family in this country had been owning this device at 
home. A similar, but much smoother trend can be observed with 
vacuum cleaners, which were present at 3 of ten houses a 
century ago but are now held by 100% of all homes. Lastly, 
washing machines were owned by 40% of families in 1920 and 
reached 70% in just four decades. These days, it has remained 
just over 70%. 
The second line chart indicates a direct correlation between the 
acquisition of essential household tools and the amount of work 
required to be done at home. Household work amount dropped 
dramatically from a high 50 hours per week in 1920 to a mere 10 
hours per week in 2019.
