Question 10

Despite its immense popularity in several Commonwealth nations, cricket has only made sporadic appearances in the Olympic Games, with efforts ongoing for its re-inclusion. Considering the demands of a multi-sport event, which format of cricket is most widely discussed for potential Olympic inclusion, and why?

Accepted Answer

C. Twenty20 (T20) cricket, owing to its shorter duration, fast-paced action, and appeal to a broader global audience. — Twenty20 (T20) cricket is the most widely discussed format for Olympic inclusion because its shorter duration (around 3 hours per match) fits well within the tight scheduling constraints of a multi-sport event. Its fast-paced, high-scoring nature is also more appealing to a diverse global audience and aligns with the Olympic desire for dynamic, accessible sports. Test and ODI formats are too lengthy for the Olympics, and 'The Hundred' is a relatively new, regionally specific format, less likely for global adoption at this stage.

Answer

A. Test Cricket, due to its historical significance and comprehensive display of skill.

Answer

B. One-Day Internationals (ODIs), offering a balanced duration and strategic depth.

Answer

D. The Hundred, as a newer, even shorter format designed for explosive entertainment.
