He feels disoppointed that he got stabbed
Answer: B. Tangible Villain
Answer: I would contend that the right answer is the B) It recalls the sculptured fronts of late antique sarcophagi.
Explanation: Just to elaborate a little on the answer, it can be added that resorting to examples from antique sarcophagi seems to be very logical, due to the rectangular shape of the frieze at St. Trophîme and to the fact that it is set against the wall of the building and that it features a series of figures placed next to each other, almost as in a procession. Most Roman sarcophagi had the shape of a rectangular box and they were only decorated on the front and the two short sides. In addition, late antique sarcophagi started to feature Christian iconography, so the artists working at St. Trophîme surely found them useful as models.
You are most likely talking about the radar, which scans and alerts the people on the submarine of other submarines, missiles, etc. nearby.
In any case, to wear an improper expression on your face (to look incredulous when a victory was announced, for example) was itself a punishable offence. There was even a word for it in Newspeak: FACECRIME, it was called.
hope that i helped :)
