The correct answer to such questions usually depended on the context. If the context has already clearly indicated the meaning of the original word, then it is not necessarily good to change the word because it may destroy the meaning and expression of the original word. However, if the context doesn't clearly state the meaning of the original word, it might be better to change the word because it can express the meaning that the original word doesn't express clearly according to the new word. Therefore, when answering such questions, one had to judge according to the specific context and not simply answer based on the meaning of the words.
