Majority of the employees may respond positively to the chairman's appeal: Implicit The chairman of the company must have assumed that the majority of the employees will respond positively to his request, that’s why he urged his employees to avoid making long phone calls. II. Most of the employees may continue to make long personal calls during working hours: Not Implicit Had the chairman assumed that even after his urge, most of the employees may continue to make long phone calls, he would not have urged them in the first place. Hence, only assumption I is implicit.
