성균관 영어경시대회 문제입니다.

1. as a person of brilliant achievement, dr.johnson is respected and sought for not only in canada but all over the world.

저기 뻘간색 for을 after로 고쳐야 한다는데 seek for(강구하다)과 seek after(찾다 /구하다)의 차이가 정확히 뭔지 모르겠어서요.;;

2. being that my car is in the garage to have its engine checked, i will not be able to pick you up tomorrow moring.

being that 을 since 로 고치라는데요~ 찾아보니 being that 로 비공식 적, 구어적으로는 ~때문에 라고 쓰이기도 한다던데;;
그럼 괜찮은거 아닌가 싶어서 왜 틀렸는지 해서요~

3. our seven-day week with its day of rest was transmitted to us from christianity; and many of the most deeply felt artistic
achievements indebted to christianity for inspiration.

이 문법은 전혀 모르겠어요 왜 저 빨간색 부분이 틀렸는지ㅜ
