5) Why is it important for children to acquire an academic English register?

Well i guess it depends on ur main language u might speek. So english is the most spoke language in the world. However spanish is the most Learned and spoke language. English just more people learned this as there first language.

Explanation:

So based on your question that states a few trees in garden and one of them is a pear tree, there are pears. But a strong wind blew, there were neither pears on the tree nor on the ground. I think the best explaination to this statement is that some one might pick up the pear tree or it can be that its the wrong tree that is blown.
