Problem: Mali:

Mali lies in the torrid zone and is among the hottest countries in the world. The thermal equator, which matches the hottest spots year-round on the planet based on the mean daily annual temperature, crosses the country. Most of Mali receives negligible rainfall and droughts are very frequent. Late June to early December is the rainy season in the southernmost area. During this time, flooding of the Niger River is common, creating the Inner Niger Delta. The vast northern desert part of Mali has a hot desert climate (Koppen climate classification (BWh) with long, extremely hot summers and scarce rainfall which decreases northwards. The central area has a hot semi-arid climate (Koppen climate classification (BSh) with very high temperatures year-round, a long, intense dry season and a brief, irregular rainy season. The little southern band possesses a tropical wet and dry climate (Koppen climate classification (Aw) very high temperatures year-round with a dry season and a rainy season.

Problem: Throughout the Hellenistic world, these Greco-Macedonian colonists considered themselves by and large superior to the native "barbarians" and excluded most non-Greeks from the upper echelons of courtly and government life. Most of the native population was not Hellenized, had little access to Greek culture and often found themselves discriminated against by their Hellenic overlords. Gymnasiums and their Greek education, for example, were for Greeks only. Greek cities and colonies may have exported Greek art and architecture as far as the Indus, but these were mostly enclaves of Greek culture for the transplanted Greek elite. The degree of influence that Greek culture had throughout the Hellenistic kingdoms was therefore highly localized and based mostly on a few great cities like Alexandria and Antioch. Some natives did learn Greek and adopt Greek ways, but this was mostly limited to a few local elites who were allowed to retain their posts by the Diadochi and also to a small number of mid-level administrators who acted as intermediaries between the Greek speaking upper class and their subjects. In the Seleucid empire for example, this group amounted to only 2.5 percent of the official class.
Native populations in the Hellenistic world were discriminated by what peoples?

Context and 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.
In practice the Brazilian president must get the prior approval of what body in order to negotiate and sign a treaty?
Answer: Congress

Problem: Alaska:

On March 27, 1964, the massive Good Friday earthquake killed 133 people and destroyed several villages and portions of large coastal communities, mainly by the resultant tsunamis and landslides. It was the second-most-powerful earthquake in the recorded history of the world, with a moment magnitude of 9.2. It was over one thousand times more powerful than the 1989 San Francisco earthquake. The time of day (5:36 pm), time of year and location of the epicenter were all cited as factors in potentially sparing thousands of lives, particularly in Anchorage.

How did the Good Friday earthquake compare to the 1998 San Francisco earthquake?
