Final answer:
To visualize a donkey, it is helpful to know what a horse looks like and the physical characteristics of a donkey.
Step-by-step explanation:
To visualize a donkey, it would be helpful to know what a horse looks like since the sentence mentions that a donkey looks like a horse, only smaller. Horses are large, four-legged animals with a mane and a tail. They are typically brown, black, or white in color. They have long legs, a muscular body, and a distinctive head shape with a long face and a short mane.
Knowing that a donkey is gray in color, has a long tail, and has big, pointy ears can also help the reader visualize it. Donkeys are smaller than horses and have a sturdier build. They are known for their long ears, but they have a similar body structure to horses.
