Question

rising and falling gas prices
in the 1970s, the united states faced high gasoline prices because of periods without
enough gas. this led to the \drive 55\ movement, which lowered speed limits around the
country.
today, gas prices are affordable and cars have become more fuel efficient. the changes
encourage some to zoom.
\i go 5 miles per hour over the limit,\ said bartender tony bonny of st. george, utah. \but
as soon as i see that 80 sign, my foot gets just a little bit heavier.\
speed limits are rising all over the country, especially in wide - open western states. the
changes reflect the fast - paced lifestyle of americans today.

Explanation:

The article states that in the 1970s, the United States faced high gasoline prices due to periods without enough gas. This led to the "Drive 55" movement. The movement's goal was likely related to fuel - efficiency. Lowering speed limits can reduce fuel consumption. Among the options, reducing the number of highway deaths (A) is not directly related to the gas - price context. Raising the speed limit (B) is the opposite of what a movement named "Drive 55" (implying a 55 mph speed limit) would do. Gas being in short supply (C) is the context (high gas prices) but not the reason for the movement. However, if we consider that lower speed limits (as in "Drive 55") can conserve fuel. In the 1970s gas - crisis context, conserving fuel (which is related to gas supply and price) could be a reason. But looking at the options again, if we assume that the movement was about fuel - efficiency (a side - effect of lower speed limits is lower fuel consumption, which is relevant when gas is expensive or in short supply). But among the given options, if we consider the direct text - based option (even with some inferential stretch), when gas was expensive (due to supply issues), lower speed limits (part of "Drive 55") can help as cars are more fuel - efficient at lower speeds. So the reason for the movement (though the options are a bit of a stretch) is because gas was in short supply and prices were high (C implies a situation where gas is scarce, and the movement is a response, even if the direct link in the text is "led to the 'Drive 55' movement" after "enough gas" issue).

Answer:

C. Because gas was in short supply and gas prices went up.
