Official Solution:

The key restriction is Technical support. Besides Morgan, only Daniel and Farid are qualified to work there.

• Registration

If Morgan is assigned to Registration, Technical support still requires two staff members. Therefore, Daniel and Farid must both be assigned to Technical support.

Exhibitor desk also requires two staff members. With Morgan at Registration and Daniel at Technical support, only Ava remains available for Exhibitor desk. Thus, the Exhibitor desk cannot be fully staffed.

Answer: No

• Exhibitor desk

If Morgan is assigned to Exhibitor desk, Daniel and Farid can fill the two Technical support positions, and Ava can fill the second Exhibitor desk position.

The remaining three staff members, Ben, Chloe, and Elena, are all qualified for Registration and Security liaison. Two of them can fill Registration and the other can fill Security liaison.

Thus, all staffing requirements can be satisfied.

Answer: Yes

• Security liaison

If Morgan is assigned to Security liaison, Daniel and Farid must fill the two Technical support positions.

Exhibitor desk then requires two staff members, but only Ava remains qualified and available for it. Therefore, the staffing requirements cannot all be satisfied.

Answer: No

Correct answers:

Registration: No
Exhibitor desk: Yes
Security liaison: No
