Even dinner time is work time

A salivating meal is soon followed by brain cracking quiz to the trainees, as soon after dinner a multimedia equipment is set in front of them for their night assignment. On this occasion, the instructors have recorded a wide selection of frogs-calls; they play one after the other, and ask the trainees to identify the types of frogs making the calls.

To a neutral person, it is a wonderful night of being entertained with unusual yet sweet melodies of frogs on this particular evening.
