In which popular rally race do participants start in Paris and finish in Senegal?

The correct answer is the Paris-Dakar Rally, a legendary off-road endurance race that gained fame for its challenging routes and diverse terrain spanning from Europe to Africa. Initially established in 1978, participants of the rally would start in Paris, France, and traverse various landscapes before reaching the finish line in Dakar, Senegal. This race tested not only the speed but also the navigation and strategy of the competitors, as they faced deserts, mountains, and other difficult conditions.

The other options pertain to different types of racing events. The Tour de France is primarily a road cycling race held in France, focusing on speed and endurance over a series of stages. The Rallye Monte-Carlo is an automobile rally that takes place in the mountainous roads of the French Alps. The African Safari Rally is another off-road race but typically takes place in Kenya and does not follow the Paris-Dakar route. Thus, the unique starting and finishing points of the Paris-Dakar Rally set it apart as the correct choice.
