Putting something in "chronological" order means putting it in the order in which it happened typically First.... Second... Third....Fourth.
Example: I went to school today. I brushed my teeth, opened my eyes, and put on clothes.
In CHRONOLOGICAL order, I (first) opened my eyes, (secondly) brushed my teeth (then) put on clothes.
Hope this helps!!
The latest recorded population (2010) that I know of is <span>817,000 people.</span>
I put C on my test because it seem most logical plus I couldn't find much to help me.
