Production delays
were notoriously difficult obstacles
to overcome until the company

more effective than the old technology (No error)
4개중에 틀린거 고르거나 no error 고르는 문제 인데 전 처음에 no error 인줄 알았어요..

more effective가 왜 틀린건가요?
그리고 모르는게 또 하나더 있습니다
New Zealand had fostered a thriving local music scene for decades, but it was not until the late 1980s when New Zealand musicians began to reach international audiences (No error)
이것도 똑같은 형식의 문제인데 제가 처음에 no error 라고 생각했었는데 알고보니깐 답이 when 이더라구요...
여기서 when이 왜 틀린겁니까?
