This is illogical. "Not only that ... but also" indicates a progressive relationship, so the positions of the two sentences should be interchanged, that is, "not only flesh and blood, but also social security".
This is illogical. It's a two-sided mistake. The first two sentences only say "good" and "delicious", only one side, and the last sentence says "high and low", which raises two sides. You can add "whether" after "photo" and "poem" respectively, or delete "low". The latter did not change French smoothly.
