What segment of the economy was boosted by oil being extracted here?
the fishing industry used the substance to create nets.
the farming industry used the substance as a fertilizer.
the glass manufacturing industry used the substance as a raw material.
the automobile industry used the substance to power cars and trucks.

The correct answer is: "The automobile industry used the substance to power cars and trucks".

Oil extraction fostered the emergence of other industries close by. These industries were mostly higher-value added steps within the same production processes, in which the main raw material used as input was oil. The emergence of these oil-related industries near the extraction plants, gave firms the opportunity of decreasing transportation costs and hence, of producing more efficiently to be more competitive in terms of prices.

The automobile industry is a perfect example of a production process in which its first step is oil extraction. This is why car industries were boosted after oil extraction started in the US territory.
