Can ant one please explain why to use "has" instead of did ?
Even though my answer was right i am still confused with when to use did or when to use has
Main point is to explain that China crushed a demonstration and that was so brutal that no other country has done it again since that moment of time.
has.............is perfect to indicate present perfect tense for a task that has begun in the past at one time and has its impact till now.
did..............we cant use did as it
