A rain shower in middle autumn. 22nd October.

We watched music video on youtube a in the beginning of today's ARW class.
The contributor chose several good music video on youtube, then he/she cut and pasted them to make that music video.
Actually, he/she chose only music videos which were high quality, so actual music video was so good even respective players played different songs.
Then we watched similar but another video which had some good players and also bad players in the video, and that sounds weren't comfortable for my ears.
Our teacher use such movies as a example of references in academic essay.
We should use only high quality and reliable references, if we don't chose such good references, our essay lose reliance and sense of unity.
So we should find high quality and reliable references for our essay, but I wonder how I can judge the study, statistic, or number is whether reliable or not.
I think, in general, the references from authorized institutions such as UN, IMF, or some laboratory are "reliable".
However, these days, I came to think that such well-known institutions are influenced by some big countries such as U.S, Russia or some western countries and their intension.
I know, it's endless (or might be meaningless) discussion.
Also, I can try to choose "suitable" references  for ARW essay as a ICU student just according to what teachers said.
But, at the same time, I can't help thinking that what kind of information is actually reliable and free from authorities.
