Answer:
To inform
Step-by-step explanation:
What does informing mean as a purpose in a text?
To put it simply, informing in a text means to provide facts, details, and obviously information about a topic. Usually, texts like articles, recipes, biographies, textbooks, encyclopedias, etc. contain this purpose.
In this case, the author is informing the audience about the Emu.
It presents facts like:
".. a large flightless African bird", "related to the emu of Australia..", ".. the ostrich lays the largest eggs of any living bird", and so on.
Ultimately, the author's main goal is to educate the audience of the behaviors and attributes of the Emu.
