The problem: Answer a question about this article:
Following Kammu's death in 806 and a succession struggle among his sons, two new offices were established in an effort to adjust the Taika-Taiho administrative structure. Through the new Emperor's Private Office, the emperor could issue administrative edicts more directly and with more self-assurance than before. The new Metropolitan Police Board replaced the largely ceremonial imperial guard units. While these two offices strengthened the emperor's position temporarily, soon they and other Chinese-style structures were bypassed in the developing state. In 838 the end of the imperial-sanctioned missions to Tang China, which had begun in 630, marked the effective end of Chinese influence. Tang China was in a state of decline, and Chinese Buddhists were severely persecuted, undermining Japanese respect for Chinese institutions. Japan began to turn inward.
What new office allowed government to issue administrative orders faster?
****
The answer: Emperor's Private Office

Problem: Please answer a question about the following article about 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 liturgical language of Islam?
A: Literary Arabic

Problem: On 28 February 1476, Pope Sixtus IV, authorized those dioceses that wished to introduce the feast to do so, and introduced it to his own diocese of Rome in 1477, with a specially composed Mass and Office of the feast. With his bull Cum praeexcelsa of 28 February 1477, in which he referred to the feast as that of the Conception of Mary, without using the word "Immaculate", he granted indulgences to those who would participate in the specially composed Mass or Office on the feast itself or during its octave, and he used the word "immaculate" of Mary, but applied instead the adjective "miraculous" to her conception. On 4 September 1483, referring to the feast as that of "the Conception of Immaculate Mary ever Virgin", he condemned both those who called it mortally sinful and heretical to hold that the "glorious and immaculate mother of God was conceived without the stain of original sin" and those who called it mortally sinful and heretical to hold that "the glorious Virgin Mary was conceived with original sin", since, he said, "up to this time there has been no decision made by the Roman Church and the Apostolic See." This decree was reaffirmed by the Council of Trent.
What happened on the final day of the month of love that was of significance was authorized by the Holy Roman Church leader ?
The answer is the following: authorized those dioceses that wished to introduce the feast to do so, and introduced it to his own diocese of Rome in 1477

Here is a question about this article: Since the end of the World Wars, the term "great power" has been joined by a number of other power classifications. Foremost among these is the concept of the superpower, used to describe those nations with overwhelming power and influence in the rest of the world. It was first coined in 1944 by William T.R. Fox and according to him, there were three superpowers: the British Empire, the United States, and the Soviet Union. But by the mid-1950s the British Empire lost its superpower status, leaving the United States and the Soviet Union as the world's superpowers.[nb 2] The term middle power has emerged for those nations which exercise a degree of global influence, but are insufficient to be decisive on international affairs. Regional powers are those whose influence is generally confined to their region of the world.
What is the answer to this question: What are middle powers?
****
So...
those nations which exercise a degree of global influence, but are insufficient to be decisive on international affairs
