Question

upward - pointing ears. male okapis also have little furry horns like giraffes horns. additionally, both giraffes and okapis have long, dark tongues, which can grab and strip leaves from trees. and just like giraffes, okapis are plant eaters, feeding on leaves, buds, twigs, and fruit.
in many ways, though, okapis are quite different from their giraffe cousins. an okapis neck is much shorter than a giraffes. this is useful, because a long neck would make it difficult to move through thick vegetation. another important difference is that giraffes are social and live in herds, while okapis are shy, solitary creatures. they tend to live alone, hiding in the dense forest. perhaps thats why most people didnt even know okapis existed until around 1900.
even though okapis tend to keep to themselves, they do have ways to communicate with each other. for example, they mark their territories by leaving scent marks with their feet. and mother okapis can communicate with their babies \silently,\ using sounds that are too low in pitch for people—and predators—to hear. thats a good thing, too, as these animals are in danger of dying out. they need all the protection from predators that they can get.
based on the text, what do okapis have in common with their giraffe cousins? select all that apply.
they were both unknown to most of the world until around 1900.
they are both able to move easily through dense rain forests.
they are both plant - eating animals that get food from trees.
they both have large, upright ears and long, dark - colored tongues.

Explanation:

1. The text states that "just like giraffes, okapis are plant - eaters, feeding on leaves, buds, twigs, and fruit" and "both giraffes and okapis have long, dark tongues, which can grab and strip leaves from trees", so they are both plant - eating animals that get food from trees.
2. It also mentions "both giraffes and okapis have long, dark tongues" and "upward - pointing ears. Male okapis also have little furry horns like giraffes' horns", indicating they both have large, upright ears and long, dark - colored tongues.
3. The text doesn't say giraffes were unknown until 1900, only okapis. And giraffes don't live in dense rain - forests as okapis do, so the first two options are incorrect.

Answer:

They are both plant - eating animals that get food from trees.
They both have large, upright ears and long, dark - colored tongues.
