答案：(C) novel

答對率 26%。
novel 你大概只記得名詞「小說」，完全沒想到它也是形容詞，意思是「新穎的、新奇的」：a novel idea（新穎的點子）、a novel approach（新的做法）。名詞義與形容詞義乍看無關，但源頭都是「新」——小說之所以叫 novel，正是因為它當年是一種「新的」文體。
空格所在句的結尾是 users may interact with them in new ways, too（使用者也會以新的方式與手機互動）——句尾的 new 與 too 直接把答案講出來了：additional features 與 ___ functions 講的都是「新」。
remote 是「遙遠的」，remote control（遙控器）的印象太強，很多人一看到就選；但「遙遠的功能」不成話。scarce（稀少的）與 accidental（意外的）語意也不合。
a novel idea／approach（新穎的點子／做法）、novelty（新奇）、remote control（遙控器）、be scarce（稀少）。
