Which is the best example of a synchronized routine?

Question

Quizplus · Accepted Answer

A synchronized routine involves two or more individuals coordinating their movements or behaviors in a rhythmic and seamless manner. The example of the baby and mother sticking their tongues out at each other demonstrates this type of synchronization as they are alternating their behaviors in response to each other.

Answer: B, D
 Neither option B (a duckling following a mother hen) nor option D (two best friends watching a hockey game) involve coordinated movements or behaviors, which are typically characteristic of synchronized routines. Therefore, they are not the best examples of synchronized routines.
