The correct answer is: C. Either I or II is implicit
The statement “Children are influenced more by their teachers nowadays” does not explicitly state that children consider teachers as their models or that a large amount of children’s time is spent in school. However, both of these assumptions are plausible and could explain why children are influenced more by their teachers nowadays.
For example, if children consider teachers as their models, they are more likely to imitate their behavior and adopt their values. Additionally, if children spend a lot of time in school, they are more likely to be exposed to their teachers’ ideas and beliefs.
Therefore, either assumption I or assumption II could be implicit in the statement.
