Which year marked the debut of men's biathlon and women's speed skating in the Olympics?

The year that marked the debut of men's biathlon and women's speed skating in the Olympics is indeed 1960. This was a significant moment in Olympic history as it expanded the range of sports featured in the Winter Games. The men's biathlon combined cross-country skiing with rifle shooting, showcasing both physical endurance and precision, while women's speed skating added gender representation to a traditionally male-dominated event in the Olympics.

1960 being the correct choice reflects the Olympic movement's aim for inclusivity and the introduction of new, diverse sporting events, appealing to a broader audience and encouraging more athletes to compete. The inclusion of these events in the 1960 Squaw Valley Winter Olympics allowed both men's and women's competitions in disciplines that were previously underrepresented, highlighting the evolving nature of the Olympic Games.
