I think the first photo is fake. First of all my prior knowledge tells that jet plains do not fly around buildings. Secondly The plain stands alone with nothing else in the background. to me that is a red flag. Lastly there looks to be a mouse pointer in the photo. which also made me a little suspicious.
Response:
After reading the blog my suspicions were confirmed. The blog went on to speak about how the light differentiation made it obvious that the picture had been Photoshop. It also pointed out the very same cursor that I pointed out. This makes me confident in my ability to analyze and detect when faulty information is being presented.
Second answer:
I thought the second hotel post was real because it was less like an advertisement. the first one was a little to descriptive for the average person leaving a review. The second post was a little shorter and to the point.
Response:
Here I made the classic mistake of assuming something was wrong because of the way the question was presented. In my answer I say that the second post was a little too descriptive. In hindsight I see that I reached a bit in order to come to a conclusion. The blog site assessing the authenticity of the hotel post went to great depth to find the truth. Their searching other blog posts that have been posted by those individuals was the smartest and most efficient way to authenticate the post.
Third answer:
I thought the second quote was the real quote as it used the more proper langue for the time period. the second quote also had less of an agenda.
Response:
The second quote was obviously the only real quote both before and after my reading of the blog. It was the only quote to use proper vernacular for the suggested time period, as well as the only quote without an obvious agenda.
