A certain strikingly colorful parrot whose habitat today is restricted to a few regions of South America is depicted in a 1,300-ycar-old Mayan mural painted on a palace wall in what is now Mexico. Although the parrot's depiction is so accurate and evocative that the artist must have been thoroughly familiar with the bird, the mural by itself provides no compelling evidence that this species' habitat ever extended into North America as far as Mexico, since .
Which of the following most logically completes the argument?
1300 years ago there was regular trade among the Mayans of Mexico and the inhabitants of several regions of South America
no other murals from the same time period that depict this species of parrot have been found in Mexico
the mural also depicts a species of parrot that is common in Mexico today
there are no tropical forests in Mexico today that could provide a habitat for the parrot
of all the animals and birds that are depicted in the mural, this parrot is the only one that docs not inhabit Mexico today
