The correct answer is: Both I and II are implicit.
The statement is an advertisement for a pharmaceutical product that claims to improve memory. The advertisement makes two assumptions:
- Assumption I: People generally opt for a medical product which is useful and has no harmful side effects.
- Assumption II: Improving memory of child is considered as important by many parents.
Assumption I is implicit because the advertisement is trying to convince people to buy the product by telling them that it is useful and has no harmful side effects. The advertisement is assuming that people will be more likely to buy the product if they believe that it is useful and safe.
Assumption II is implicit because the advertisement is trying to convince parents to buy the product by telling them that it will improve their child’s memory. The advertisement is assuming that parents care about their child’s memory and will be more likely to buy the product if they believe that it will improve their child’s memory.
Both assumptions are necessary for the advertisement to be persuasive. If assumption I is not true, then people will not be more likely to buy the product even if they believe that it will improve their child’s memory. If assumption II is not true, then parents will not be more likely to buy the product even if they believe that it is useful and safe.
