Task: Story Composition
Input (English): Background Paragraph: Gasoline-powered vehicles emit a lot of harmful materials. Nitrogen oxides are formed when atmospheric nitrogen reacts with oxygen at the high temperatures found in a car engine. Carbon monoxide is a by-product of incomplete combustion of hydrocarbons. Evaporated and unused fuel releases volatile hydrocarbons into the atmosphere to help form smog. The presence of a catalytic converter in the exhaust system of the car causes these materials to react and be changed into less harmful products.
Output (English): Due to economic sanctions and trade embargoes, Cuban citizens primarily use cars designed in the late 1940s and early 1950s. These cars contain engines that were designed before the introduction of the catalytic converter. Meanwhile trade relations between nearby Panama and Japan have enabled the citizens of Panama to drive cars with the most up to date catalytic converter technology possible.
