Problem: Please answer a question about the following article about States of Germany:
The Basic Law of the Federal Republic of Germany, the federal constitution, stipulates that the structure of each Federal State's government must "conform to the principles of republican, democratic, and social government, based on the rule of law" (Article 28). Most of the states are governed by a cabinet led by a Ministerpräsident (Minister-President), together with a unicameral legislative body known as the Landtag (State Diet).

The Minister-President appoints a cabinet to run the state's agencies and to carry out the executive duties of the state's government.
Who does Minister-President choose to run state agencies?
A: a cabinet


Question: Read this and answer the question

The Brazilian federal constitution states that the power to enter into treaties is vested in the president and that such treaties must be approved by Congress (articles 84, clause VIII, and 49, clause I). In practice, this has been interpreted as meaning that the executive branch is free to negotiate and sign a treaty, but its ratification by the president is contingent upon the prior approval of Congress. Additionally, the Federal Supreme Court has ruled that, following ratification and entry into force, a treaty must be incorporated into domestic law by means of a presidential decree published in the federal register in order to be valid in Brazil and applicable by the Brazilian authorities.

What Brazilian institution has ruled that a treaty must be incorporated into domestic law by means of a presidential decree?
Answer: the Federal Supreme Court

Besides emptiness, Mahayana schools often place emphasis on the notions of perfected spiritual insight (prajñāpāramitā) and Buddha-nature (tathāgatagarbha). There are conflicting interpretations of the tathāgatagarbha in Mahāyāna thought. The idea may be traced to Abhidharma, and ultimately to statements of the Buddha in the Nikāyas. In Tibetan Buddhism, according to the Sakya school, tathāgatagarbha is the inseparability of the clarity and emptiness of one's mind. In Nyingma, tathāgatagarbha also generally refers to inseparability of the clarity and emptiness of one's mind. According to the Gelug school, it is the potential for sentient beings to awaken since they are empty (i.e. dependently originated). According to the Jonang school, it refers to the innate qualities of the mind that expresses themselves as omniscience etc. when adventitious obscurations are removed. The "Tathāgatagarbha Sutras" are a collection of Mahayana sutras that present a unique model of Buddha-nature. Even though this collection was generally ignored in India, East Asian Buddhism provides some significance to these texts.
What does tathagatagarbha mean?
Buddha-nature


Here is a question about this article: As the premiers did not come to an agreement on this question, the Parliamentary Council was supposed to address this issue. Its provisions are reflected in Article 29. There was a binding provision for a new delimitation of the federal territory: the Federal Territory must be revised ... (paragraph 1). Moreover, in territories or parts of territories whose affiliation with a Land had changed after 8 May 1945 without a referendum, people were allowed to petition for a revision of the current status within a year after the promulgation of the Basic Law (paragraph 2). If at least one tenth of those entitled to vote in Bundestag elections were in favour of a revision, the federal government had to include the proposal into its legislation. Then a referendum was required in each territory or part of a territory whose affiliation was to be changed (paragraph 3). The proposal should not take effect if within any of the affected territories a majority rejected the change. In this case, the bill had to be introduced again and after passing had to be confirmed by referendum in the Federal Republic as a whole (paragraph 4). The reorganization should be completed within three years after the Basic Law had come into force (paragraph 6).
What is the answer to this question: What was required in each territory or part of a territory whose affiliation was to be changed? 
****
So...
a referendum
