I want to know the answer to the following question:
The shrine of San Vittore in ciel d'oro had mosaics from which century?
All the background I'm provided with is that "In the small shrine of San Vittore in ciel d'oro, now a chapel of Sant'Ambrogio, every surface is covered with mosaics from the second half of the 5th century.". Is that enough to answer the question?
Answer: yes
