Had the Archduke Franz Ferdinand not been assassinated, then maybe the war wouldn't have been declared.
No
Realistically, probably not. It is possible that WW2 could have been, though, had the terms of the Treaty of Versailles been somewhat more reasonable. The insistence on extremely punitive terms for Germany more or less ensured that there would be a second war.

how could apartheid have been prevented.
The Mexican oil spill could have been prevented. All oil spills could have been prevented if it weren't for careless people! An automatic switch should have been installed on the inside of the pipe.

The fire at the Triangle Shirtwaist Factory could certainly have been prevented with the knowledge and procedures we use today. Its death toll could have been reduced if the doors had not been locked and the switchboard on the 9th floor had been in operation. Whether the fire could have been completely prevented with the technology and procedures of the day is an open question that can never be completely answered.
If communist North Vietnam did not try to conquer South Vietnam, the war would have been prevented.
maybe
Yes.
It couldn't. Cyclones are a natural weather phenomenon which cannot be prevented or controlled.
