Question

what was the condition of games half a century ago

Answer 1

a cricketer should score at least 50 runs

Answer 2

1) It became common to pitch the ball through the air, rather than

roll it along the ground.

2) It also opened new possibilities for spin and swing. In response,

batsmen had to master timing and shot selection.

3) The curved bat was replaced with the straight one. All this raised

the premium on skill and reduced the influence of rough ground

and brute force.
