Answer

- I go to school -> 나는 학교(를/에) 다닌다.

- I go to college -> 나는 대학교(를/에) 다닌다.

- the signal in the area is poor/bad/weak => 이 지역은 전파[신호]가 안 좋다/나쁘다/약하다.

- Only whatsapp allowed -> 와츠앱만 허용된다 [허용한다, 받아준다].

- I work at plantation company -> 나는 픞랜테이션 회사에서 일한다.

- palm oil mill - 팜유 [팜오일] 공장 
* "유" is a hanja-based word for oil; 기름 is a native word for "oil".
