Which factors are most likely to cause an unintentional event to occur? check all that apply.

a people overlooking important evidence

b leaders making mistakes in judgment

c people acting without thinking of the consequences

d leaders making reforms on purpose

e people acting without a larger goal or plan

The answer is B and D.  The only way an untentional event can occur is when people involved make a mistake during the decision-making process, or when they try to make a reform.  In these cases, if something wrong happens, it could have been beyond their control. But, if people overlook important evidence, ignore possible consequences or don't follow a plan, an accident could almost be considered intentional.

the protestant reformation's started in 1517, disturbing the religious and political order in europe´s catholic countries. the outcome was the european wars of religion prosecuted in europe in the 16th, 17th and part of the 18th century. nonetheless, uprisings, territorial disputes, and great power conflicts were also causes of the wars.
