Question

percentage of us homes with electricity
which statement is supported by information presented
in the chart?
o people owned fewer electrical appliances in the
1920s than in earlier decades.
o more rural homes than urban homes had access to
electricity in the 1920s.
o the number of houses with electricity would
decrease after the 1930s.
o demand for electricity increased in the 1920s and
1930s.

Explanation:

• The first option: The chart shows the percentage of homes with electricity, not the number of electrical appliances owned. So this option is not supported.
• The second option: The chart does not compare rural and urban homes in terms of quantity (only shows percentages). So this option is not supported.
• The third option: The chart only shows data up to 1930. There is no information to predict what happens after 1930. So this option is not supported.
• The fourth option: As the percentage of homes (both all homes and urban homes) with electricity increased from 1910 - 1930, it implies that more homes were using electricity. An increase in the number of homes using electricity would lead to an increase in demand for electricity.

Answer:

Demand for electricity increased in the 1920s and 1930s.
