Why are there only two worda left to pick?
There weren't any for me.
"...khoa học có thể giải thích sự tồn tại của ma" - thật à?
Two problems with this sentence: one, it should be ghosts, not ghost, and two, logically if you say "but" it implies that what follows will not be consistent with what came before, so it should read "science cannot explain the existence of ghosts".
Actually it's meaning to say "I am not superstitious but I believe science can explain the existence of ghosts".
"Science cannot explain..." is "Khoa học không thể giải thích..."
