The early ancestors of the horse (shown in the picture) were adapted to life in tropical forests. Gradually the forests disappeared and were replaced with open grasslands. Because of the gradual change in habitat, modern horses

A) have five toes that allow them to walk well on soft ground.
B) are herbivores instead of carnivores like their early ancestors.
C) are taller with long legs and are capable of great speed to escape predators.
D) have gradually grown larger, but show no major changes from the early ancestors.

try to use process of elimination: ex: eliminate A (modern horses don't have five toes, they only have one. it's the ancestral horses that had five.) and D (if you compare modern vs. ancestral horse species they're very different.)

repeat the process to distinguish between B+C. which one is actually true for *modern* horses?
