As you can see below, I created some default questions which are supposed to ask about events that either have happened or will happen in future(the gaps will be filled by different events such as "New Year" or "First World War" etc. ).
Are any of the following questions poorly-formed, provided that the ellipsis represents an event?
Is ... an event?
Where is ... started?
Where has ... taken place?
Where is ... finished?
Who has participated in ... ?
Who has organized ... ?
For whom was ... advantageous or disadvantageous ?
When is ... started ?
When is ... finished ?
What happens in ... ?
What major events happened at ... ?
What reasons made ... happen ?

Why has ... started ?
