The correct answer is: Only assumption I is implicit.
The statement says that the civic authority has advised the residents to use mosquito repellents or sleep inside nets. This means that the civic authority believes that using mosquito repellents or sleeping inside nets will help to prevent malaria. However, the statement does not say anything about whether or not the residents have enough money to buy mosquito repellents or nets. Therefore, assumption I is implicit.
Assumption II is not implicit. The statement does not say anything about whether or not people will ignore the advice and continue to get mosquito bites. It is possible that people will follow the advice and use mosquito repellents or sleep inside nets. It is also possible that people will ignore the advice and continue to get mosquito bites. Therefore, assumption II is not implicit.
