Input: Article: The apse mosaic of the Gelati Monastery is a rare example of mosaic use in Georgia. Began by king David IV and completed by his son Demetrius I of Georgia, the fragmentary panel depicts Theotokos flanked by two archangels. The use of mosaic in Gelati attests to some Byzantine influence in the country and was a demonstration of the imperial ambition of the Bagrationids. The mosaic covered church could compete in magnificence with the churches of Constantinople. Gelati is one of few mosaic creations which survived in Georgia but fragments prove that the early churches of Pitsunda and Tsromi were also decorated with mosaic as well as other, lesser known sites. The destroyed 6th century mosaic floors in the Pitsunda Cathedral have been inspired by Roman prototypes. In Tsromi the tesserae are still visible on the walls of the 7th-century church but only faint lines hint at the original scheme. Its central figure was Christ standing and displaying a scroll with Georgian text.

Now answer this question: Who was the central theme of the mosaics at Tsromi?

Output: Christ

Input: Article: Unlike Modern English, Old English is a language rich in morphological diversity. It maintains several distinct cases: the nominative, accusative, genitive, dative and (vestigially) instrumental. The only remnants of this system in Modern English are in the forms of a few pronouns (such as I/me/mine, she/her, who/whom/whose) and in the possessive ending -'s, which derives from the old (masculine and neuter) genitive ending -es. In Old English, however, nouns and their modifying words take appropriate endings depending on their case.

Now answer this question: What trait does Old English possess that Modern English lacks?

Output: morphological diversity

Input: Article: Ibn Sina subsequently settled at Rey, in the vicinity of modern Tehran, the home town of Rhazes; where Majd Addaula, a son of the last Buwayhid emir, was nominal ruler under the regency of his mother (Seyyedeh Khatun). About thirty of Ibn Sina's shorter works are said to have been composed in Rey. Constant feuds which raged between the regent and her second son, Shams al-Daula, however, compelled the scholar to quit the place. After a brief sojourn at Qazvin he passed southwards to Hamadãn where Shams al-Daula, another Buwayhid emir, had established himself. At first, Ibn Sina entered into the service of a high-born lady; but the emir, hearing of his arrival, called him in as medical attendant, and sent him back with presents to his dwelling. Ibn Sina was even raised to the office of vizier. The emir decreed that he should be banished from the country. Ibn Sina, however, remained hidden for forty days in sheikh Ahmed Fadhel's house, until a fresh attack of illness induced the emir to restore him to his post. Even during this perturbed time, Ibn Sina persevered with his studies and teaching. Every evening, extracts from his great works, the Canon and the Sanatio, were dictated and explained to his pupils. On the death of the emir, Ibn Sina ceased to be vizier and hid himself in the house of an apothecary, where, with intense assiduity, he continued the composition of his works.

Now answer this question: What office did Ibn Sina receive in Hamadan?

Output:
office of vizier
