Problem: Gymnastics:

In the past, the floor exercise event was executed on the bare floor or mats such as wrestling mats. Today, the floor event occurs on a carpeted 12m 12m square, usually consisting of hard foam over a layer of plywood, which is supported by springs or foam blocks generally called a "spring" floor. This provides a firm surface that provides extra bounce or spring when compressed, allowing gymnasts to achieve greater height and a softer landing after the composed skill. Gymnasts perform a choreographed routine up to 90 seconds in the floor exercise event; Depending on the level, they may choose their own, or, if known as a "compulsory gymnast," default music must be played. In some gymnastic associations such as United States Association of Gymnastic Clubs (USAIGC), gymnasts are allowed to have vocals in their music but at USA Gymnastics competitions a large deduction is taken from the score for having vocals in the music. The routine should consist of tumbling lines, series of jumps, leaps, dance elements, acrobatic skills, and turns, or piviots, on one foot. A gymnast can perform up to four tumbling lines that usually includes at least one flight element without hand support. Each level of gymnastics requires the athlete to perform a different number of tumbling passes. In level 7 in the United States, a gymnast is required to do 23, and in levels 810, at least 34 tumbling passes are required.

Problem: Mosaic:

The craft has also been popular in early medieval Rus, inherited as part of the Byzantine tradition. Yaroslav, the Grand Prince of the Kievan Rus' built a large cathedral in his capital, Kiev. The model of the church was the Hagia Sophia in Constantinople, and it was also called Saint Sophia Cathedral. It was built mainly by Byzantine master craftsmen, sent by Constantine Monomachos, between 1037 and 1046. Naturally the more important surfaces in the interior were decorated with golden mosaics. In the dome we can see the traditional stern Pantokrator supported by angels. Between the 12 windows of the drum were apostles and the four evangelists on the pendentives. The apse is dominated by an orant Theotokos with a Deesis in three medallions above. Below is a Communion of the Apostles.

What was used as a model for the church Yaroslav commissioned?

A:
the Hagia Sophia
