Note 01: Image with incorrect text alternative
The text alternative for this image of text is overly verbose and does not serve the equivalent purpose of the image. The text alternative is as follows:
<img width="250" height="65" src="../img/logo.svg" alt="Red dot with a white letter 'C' that symbolizes a moon crescent as well as the sun. This logo is followed by a black banner that says 'CITYLIGHTS' which is the name of this online portal. Finally, the slogan of the portal, 'your access to the city', follows in a turquoise green handwriting style and with a slight slant across the top banner." ... >

srcset="../img/concert-image@2x.jpg 2x,
../img/concert-image@3x.jpg 3x"

alt="image" >

Note 06: Reading sequence not meaningful
These three columns of text appear to be visually distinct but according to the markup code they appear as one piece of running text. They would read as follows:
"After three years of effort city scientists now agree that the primary cause of the 2003 heatwave was hot air from our Mayor: These kinds of crimes need more creative, effective punishments. For example, we could require compulsory Brain donations: huge drop off in brain donations down due to the 'success' of 'Slow Traffic, Safe Streets' policy"
