Correct answer

  • AEl motor emitirá más gases contaminantes.The engine will emit more polluting gases.
Explanation

With a dirty air filter, less air gets into the engine: the mixture becomes rich, not lean, and combustion is incomplete. As a result, the engine emits more polluting gases and also uses more fuel.
