This question is pretty simple but wonder, I am the only one to find the wording confusing?
The question comes out of official preparation for Executive Assessment:

Adiliah, Bao, Davi, Laszlo, Saleema, and Yarah work in a firm’s legal department. Adiliah supervises Bao and Davi, Davi supervises Laszlo, and Laszlo supervises Saleema and Yarah. These are the only supervisory relationships involving these six employees. Each document that the department processes must be initially reviewed by exactly one department member. Each document reviewed by a department member must then be reviewed by that person’s supervisor. No other rules require anyone else to review any document. Anyone not required to review a given document will not review it.

Select Laszlo among reviewers for the maximum number of department members that could have reviewed a single document if Laszlo was among the reviewers. Select Adiliah among reviewers for the maximum number of department members that could have reviewed a single document if Adiliah was among the reviewers. Make only two selections, one in each column.

Lazlo among reviewers Adiliah among reviewers

Official response:
If Laszlo reviews a document, so must his supervisor, Davi, and Davi’s supervisor, Adiliah. If Laszlo is the initial reviewer, then exactly three department members would review the document. However, if Laszlo reviews a document but is not the initial reviewer, the initial reviewer must be either Saleema or Yarah for a maximum total of 4 reviewers of the document.

The correct answer is 4.

If Adiliah reviews a document, no department members will review the document after her. If Adiliah is the initial reviewer, then, exactly 1 department member will review the document. If Bao or Davi is the initial reviewer, then the document will be reviewed by exactly 2 department members. If Laszlo is the initial reviewer, then the document will be reviewed by exactly 3 department members. Finally, if Saleema or Yarah is the initial reviewer, then exactly 4 department members will review the document. Since no one else can be the initial reviewer, 4 must be the maximum number of reviewers of a single document for which Adiliah is among the reviewers.

The correct answer is 4.

I find it confusing because it is against the rule stated in the problem:
- Each document reviewed by a department member must then be reviewed by that person’s supervisor.
- No other rules require anyone else to review any document.
- Anyone not required to review a given document will not review it.
Basically, it tells me - there are only 2 reviewers for the document!
If Lazlo is the initial review - only Davie needs to review as a manager, why in the world would Davie's boss need to review? If Salema does the initial review, isn't Lazlo's review sufficient? Why a such redundancy needed? Am I the only one confused by wording? On the other hand, I agree that if there are only 2 reviewers for the document, then the problem does not make sense in the first place!

The point to note here is that the document MUST be reviewed by that person's supervisor. It's like a chain and the supervisor's supervisor also needs to review per the rule stated.

Thank you for response! I 100% agree that the document MUST be reviewed by that persons' supervisor. But where it is stated that supervisor's supervisor must review it? Please read the rules
" - Each document reviewed by a department member must then be reviewed by that person’s supervisor.
- No other rules require anyone else to review any document.
- Anyone not required to review a given document will not review it"

Nothing about reviewing supervisor's review and further it is implied that no redundant or excessive review should be done (last 2 rules)...
