the omission of the word 'that' in this sentence, shouldn't be considered wrong. It's perfectly correct English
Agree. You can also skip the "It" in "It turns out”, but it's marked wrong as well.
Indonesian doesn't use gender specific pronouns, the word "dia" in this case could mean either "he" or "she".
I always thought so!
Dia means either she or he
"Turns out she is involved with them." Apa kalimat ini betul?
He/she = dia
Ternyata bukannya memakai 'actually' ya? It turns out beda arti lha dengan ternyata
