구해커스토익책인데요.

1 If long-term (    ) is a possibility at this company, I would be interested and willing to relocate myself to this site. 정답이 employment 인데요. 앞에 관사나 뒤에 s가 안붙어도 되나요?

마찬가지로 It is common practice today for psychologists to serve as consultants to toy companies in the design of toys for children of different ages. 에서 practice 앞위 관사나 s가 안붙었잖아요. 왜죠?

2.The general manager handles the supervisor of all employees. 에서 supervisor가 supervision으로 되어야 한다는데 슈퍼바이저 감독이란 뜻으로도 문장이 가능하지 않나요?

3. When the (profit reports) and monthly (statement) are finished, please pass them (on to)
                                a                                             b                                                                           c  
the general manager's (office).
                                                d
여기서 b가 틀렸는데요. a monthly statement 또는 statements 바뀌어져야 한답니다. 제생각에는 앞에 the가 statement까지 커버할 수 있지 않나요?


읽어주셔서 감사합니다.
