Question

the power of carrots
do you think carrots are only those crunchy orange sticks on a snack tray or the wilted orange circles in a stew? think again! the humble carrot has many benefits to humans and can also be full of surprises.
a long, long history
there is no way of knowing exactly when or how humans began growing carrots, but people have been eating the vegetable for over 1,000 years. at first, the plants grew wild, and, while ancient greeks and romans wrote about gathering them for medicine, they were not considered food. scientists think that people first grew carrots as a food crop sometime before the 900s in the iranian plateau.
from there, traders carried carrots along the ancient silk road that stretched to syria and across north africa in the 1000s to the 1100s.

what text structure does the author use?
cause and effect
chronological order
description
problem and solution

Explanation:

El texto presenta eventos en el orden en que ocurrieron: primero las plantas crecían silvestres, luego los griegos y romanos las usaron para medicina, después se cultivaron como cultivo alimentario en el Iranian Plateau. Este orden temporal (con expresiones como "at first", "for over 1,000 years", "sometime before the 900s") indica el uso de la estructura de orden cronológico. Otras estructuras (causa y efecto, descripción, problema y solución) no se aplican aquí, ya que no hay relación causa - efecto, descripción detallada de un solo tema o presentación de problema y solución.

Answer:

chronological order
