Grade 4 English reading comprehension: The upside-down tree

A sample of the passage

In the hot, dry parts of Limpopo, a very strange tree stands against the sky. Its trunk is so wide that several learners holding hands could not reach round it, and its bare branches twist in all directions. Many people say that it looks as if someone planted it upside down, with its roots in the air. This tree is the baobab.
