The line graph illustrates the prices of mansions, in US dollars, across three countries (A, B, and C) from 1978 to 2014.
Overall, Country A consistently had the highest housing prices, while Country B generally had the lowest. Although the prices of residential properties fluctuated in all three countries, each experienced unique trends over the given period.
In 1978, house prices in all three countries were around $100,000. Over the following years, Country A experienced a modest increase, reaching approximately $200,000 by 1979, while prices in Countries B and C remained relatively stable until 1981, when Country A’s housing prices briefly dropped back to levels close to the initial $100,000.
From 1984 onward, property values in Country B began a gradual rise, peaking at nearly $400,000 in 2002 before declining to around half that value. However, they rose again to regain their previous peak by 2014.
Meanwhile, Country A saw a steady upward trend in housing prices from 1990, reaching just above $600,000 in 2002, and ultimately ending the period with the highest property values at $800,000. In contrast, Country C’s housing prices fluctuated significantly throughout the period but concluded at a relatively lower value, around $450,000 in 2014.
