savory 鹹的；香辣的while 是連接詞, however 是副詞若將 snacks 後面的句點改為逗點，那麼 however 就要換成 while (或 whereas) 且不能再使用 however，此時句子就變成 Some people like sweet snacks, while others like savory ones. (有人喜歡吃甜食, 不過就有人喜歡吃鹹的)。若將 snacks 後面的句點改為分號 (;)，那麼 however 就不能用 while (或 whereas) 來替換，且 however 須小寫，此時句子就變成 Some people like sweet snacks; however, others like savory ones.

不知道有沒有人，跟我一樣會直接選However。查了一下，選However，前後都要有逗號。Ex:There may, however, be other ways that we haven’t tried. 資料來源:安雅英文｜多益-%23toeic
