Problem: Mosaic:

The Church of the Holy Apostles in Thessaloniki was built in 1310–14. Although some vandal systematically removed the gold tesserae of the background it can be seen that the Pantokrator and the prophets in the dome follow the traditional Byzantine pattern. Many details are similar to the Pammakaristos mosaics so it is supposed that the same team of mosaicists worked in both buildings. Another building with a related mosaic decoration is the Theotokos Paregoritissa Church in Arta. The church was established by the Despot of Epirus in 1294–96. In the dome is the traditional stern Pantokrator, with prophets and cherubim below.

Where is the Theotokos Paregoritissa Church located?
---
A: Arta


Problem: Dialect:

In Tunisia, Algeria, and Morocco, the Darijas (spoken North African languages) are sometimes considered more different from other Arabic dialects. Officially, North African countries prefer to give preference to the Literary Arabic and conduct much of their political and religious life in it (adherence to Islam), and refrain from declaring each country's specific variety to be a separate language, because Literary Arabic is the liturgical language of Islam and the language of the Islamic sacred book, the Qur'an. Although, especially since the 1960s, the Darijas are occupying an increasing use and influence in the cultural life of these countries. Examples of cultural elements where Darijas' use became dominant include: theatre, film, music, television, advertisement, social media, folk-tale books and companies' names.

What is the dominant religion of North Africa?
---
A: Islam

Problem: Red:

The Romans liked bright colors, and many Roman villas were decorated with vivid red murals. The pigment used for many of the murals was called vermilion, and it came from the mineral cinnabar, a common ore of mercury. It was one of the finest reds of ancient times – the paintings have retained their brightness for more than twenty centuries. The source of cinnabar for the Romans was a group of mines near Almadén, southwest of Madrid, in Spain. Working in the mines was extremely dangerous, since mercury is highly toxic; the miners were slaves or prisoners, and being sent to the cinnabar mines was a virtual death sentence.

Along with slaves, who was sent to work in cinnabar mines in Rome?
---
A:
prisoners
