Answer:
colonial languages
Explanation:
The fact that Spanish is the official language of some twenty countries in the Americas is a direct result of colonization. Like the Portuguese spoken in Brazil or the French and English spoken in Canada, Spanish was brought to the New World by European colonists and did not originate in the Americas.
The case of Senegal is more complex since Wolof is also widely spoken in the country, but the status of French as the administrative and official language is a result of the French colonization of the Senegal and many other West African nations.

Las Vegas is a city located in Nevada, and it is actually the largest city in this state. The city is located in the Mohave Desert, so it has a desert climate. It is actually located near the Death Valley, but its temperatures are slightly milder because its elevation is between 500 and 900 meters above sea level.
The summers are hot, while the winters have mild temperatures, with the nights being colder. The precipitation levels are around 110 mm annually, and most of them come in the winter as light rain, while the very rare ones that occur in the summer are in the form of showers.
The climate of Las Vegas is like this because the area is in a rain shadow because of the mountain ranges on the west of it. The mountains are blocking almost rainfall, which falls on their windward side, while the leeward side and the valleys east of it are very dry.
