Problem: Greek figural mosaics could have been copied or adapted paintings, a far more prestigious artform, and the style was enthusiastically adopted by the Romans so that large floor mosaics enriched the floors of Hellenistic villas and Roman dwellings from Britain to Dura-Europos. Most recorded names of Roman mosaic workers are Greek, suggesting they dominated high quality work across the empire; no doubt most ordinary craftsmen were slaves. Splendid mosaic floors are found in Roman villas across North Africa, in places such as Carthage, and can still be seen in the extensive collection in Bardo Museum in Tunis, Tunisia.
Often regular everyday craftsman were most likely what?
The answer is the following: slaves

Problem: The papal bull defining the dogma, Ineffabilis Deus, mentioned in particular the patrististic interpretation of Genesis 3:15 as referring to a woman, Mary, who would be eternally at enmity with the evil serpent and completely triumphing over him. It said the Fathers saw foreshadowings of Mary's "wondrous abundance of divine gifts and original innocence" "in that ark of Noah, which was built by divine command and escaped entirely safe and sound from the common shipwreck of the whole world; in the ladder which Jacob saw reaching from the earth to heaven, by whose rungs the angels of God ascended and descended, and on whose top the Lord himself leaned; in that bush which Moses saw in the holy place burning on all sides, which was not consumed or injured in any way but grew green and blossomed beautifully; in that impregnable tower before the enemy, from which hung a thousand bucklers and all the armor of the strong; in that garden enclosed on all sides, which cannot be violated or corrupted by any deceitful plots; in that resplendent city of God, which has its foundations on the holy mountains; in that most august temple of God, which, radiant with divine splendours, is full of the glory of God; and in very many other biblical types of this kind."
Where was Mary represented (according to the Holy document ) on the vessel that wandered the sea for forty days and forty nights ?
The answer is the following: in that ark of Noah, which was built by divine command and escaped entirely safe and sound from the common shipwreck of the whole world

Problem: It was imperative for Japanese commanders to hold Saipan. The only way to do this was to destroy the U.S. Fifth Fleet, which had 15 fleet carriers and 956 planes, 7 battleships, 28 submarines, and 69 destroyers, as well as several light and heavy cruisers. Vice Admiral Jisaburo Ozawa attacked with nine-tenths of Japan's fighting fleet, which included nine carriers with 473 planes, 5 battleships, several cruisers, and 28 destroyers. Ozawa's pilots were outnumbered 2:1 and their aircraft were becoming or were already obsolete. The Japanese had considerable antiaircraft defenses but lacked proximity fuzes or good radar. With the odds against him, Ozawa devised an appropriate strategy. His planes had greater range because they were not weighed down with protective armor; they could attack at about 480 km (300 mi)[citation needed], and could search a radius of 900 km[citation needed] (560 mi). U.S. Navy Hellcat fighters could only attack within 200 miles (320 km) and only search within a 325-mile (523 km)[citation needed] radius. Ozawa planned to use this advantage by positioning his fleet 300 miles (480 km)[citation needed] out. The Japanese planes would hit the U.S. carriers, land at Guam to refuel, then hit the enemy again when returning to their carriers. Ozawa also counted on about 500 land-based planes at Guam and other islands.
How many fleet carriers did the U.S. Fifth Fleet have?
The answer is the following: 15

Problem: By the mid-7th century, English and Irish missionaries set out to convert the Frisians. The pope appointed their leader, Willibrordus, bishop of the Frisians. The tenure of Willibrordus is generally considered to be the beginning of the Bishopric of Utrecht. In 723, the Frankish leader Charles Martel bestowed the fortress in Utrecht and the surrounding lands as the base of the bishops. From then on Utrecht became one of the most influential seats of power for the Roman Catholic Church in the Netherlands. The archbishops of Utrecht were based at the uneasy northern border of the Carolingian Empire. In addition, the city of Utrecht had competition from the nearby trading centre Dorestad. After the fall of Dorestad around 850, Utrecht became one of the most important cities in the Netherlands. The importance of Utrecht as a centre of Christianity is illustrated by the election of the Utrecht-born Adriaan Florenszoon Boeyens as pope in 1522 (the last non-Italian pope before John Paul II).
What year did Utrecht gain in power 
The answer is the following:
After the fall of Dorestad around 850, Utrecht became one of the most important cities in the Netherlands
