D must perform if Z is performing. This is not the other way around. If Z is not performing, D can perform but D has to perform if Z is performing.

I still think the question is ill-framed. If Demi has performed, I believe either of Iris or Zozibini has performed as per the language.
So the answer should be 4,4.

Hey!

My two cents: The question is correctly framed. Let me try to explain why!

Example to understand the logic here

-> If D performs, then P must perform.

Observe: This does not mean that P cannot perform otherwise. It is possible that P performs even when D does not perform.

In reality,
- If D performs, then P must perform
- If D does not perform, we do not know. P may/may not perform. We cannot assume that P will perform only if D performs.

Similarly ->

-> If I or Z perform, then D must perform.

Observe: This does not mean that if neither I nor Z perform, then D will not perform. It is possible that D performs even when neither I nor Z perform.

In reality,
- If I or Z perform, then D must perform.
- If Neither I nor Z perform, we do not know. D may or may not perform.

In other words, just because D performs, we cannot say that I or Z have performed. We cannot assume that D will perform only in the situation where either I or Z perform.

Hope this made some sense.

Andrea, Christiane, Demi, Iris, Paulina, and Zozibini are six contestants in a reality TV show. On a special two-hour episode, some of these contestants will perform. Andrea must perform if either Christiane or Paulina performs. Paulina must perform if Demi performs. Demi must perform if either Iris or Zozibini performs. There are no other restrictions.

Select Demi performs for the minimum number of contestants who must perform in the special two-hour episode if the episode includes Demi’s performance and select Zozibini performs for the minimum number of contestants who must perform in the special two-hour episode if the episode includes Zozibini’s performance.

­Experts' Global Explanation:

I.
Paulina must perform if Demi performs.
Andrea must perform if Paulina performs.
There are no other conditions specified that necessarily require any other contestant to perform.
Thus, the minimum number of contestants who must perform in the special two-hour episode if the episode includes Demi’s performance is 3 (Demi, Paulina, and Andrea).

II.
Demi must perform if Zozibini performs.
Paulina must perform if Demi performs.
Andrea must perform if Paulina performs.
There are no other conditions specified that necessarily require any other contestant to perform.
Thus, the minimum number of contestants who must perform in the special two-hour episode, if the episode includes Zozibini’s performance is 4 (Zozibini, Demi, Paulina, and Andrea).

Hence, for “Demi performs” column, “3”, and for “Zozibini performs” column, “4” is the correct combination of the answer choices.
