The correct answer is: Only assumption II is implicit.
The shopkeeper’s statement does not provide any evidence that the customer normally accepts the shopkeeper’s recommendation. It is possible that the customer chose product B for some other reason, such as personal preference or a recommendation from a friend. However, the shopkeeper’s statement does provide evidence that the shopkeeper believes that use of international technology is supposed to ensure better quality standards. The shopkeeper is trying to persuade the customer to buy product B by pointing out that it is the only product that is based on international technology. This suggests that the shopkeeper believes that use of international technology is a sign of quality.
