I think you're a little off Nikyma. For 2 you put C, meaning B for question 4, meaning there are 2 answer Ds. But you only have 1 D. I originally thought this was right too.

Good try Nikyma, but I think you got tangled up in Question 2.

I think the answer is :
Spoiler for ANY KEY

here is how i figured my answer out:
the_answer_of_5_easy_questions__.PNG
Explaination is below:
all i was trying to do is to rule out every answer which is not correct due to contest(who wouldn't :P ),and i begin with the 3rd question,suppose the answer is A,B,C,D, and here we go:
for #1:if 3rd=A, then 1st=D; then 2nd=B;then 4th=A, which indicates the number of questions which have D B as the correct answer is:
</STRONG>A. 0
B. 2
C. 3
D. 1
according to what we got now(which is C,D,B,C for questions 1,2,3,4 ), we would certainly put D to question 5(we do have only one D in C,D,B,C )then we will immediately find out that at the moment we got two Ds, which violates our agreement with question 4 where we put a C(4. The number of questions which have D as the correct answer is:
A. 3
B. 2
C. 1
D. 0 )
BUT if we change the answer to the 5th question to B, which indicates 2 B in all the answers(we got one in the last four questions and, the last one just play a role of duo), we can find all the answers just fit perfectly.


So with no doubt, the answer is C,D,B,C,B. :)
