It has been very successful and has led to a 44% 23 in smokers wanting to kick the habit.
答案：(A) increase
an increase in 是「…的增加」，a 44% increase in smokers wanting to kick the habit 指想戒菸的人增加了四成四；change（改變）語意不明確，portion（部分）不與百分比這樣搭配，drop（下降）與前面的 very successful 矛盾。
increase 你記得的大概是動詞「增加」（Prices increased.），較少把它當名詞用。名詞的 increase 有固定的字詞搭配：an increase 「in」 + 增加的項目、a 44% increase（增加了 44%），介系詞用 in 不用 of。
作答線索在空格後面那一整組名詞，不是只有 smokers。原句是 a 44% ___ in smokers wanting to kick the habit（想戒菸的吸菸者…了 44%），wanting to kick the habit 是後位修飾，被計數的是「想戒菸的人」，不是吸菸人口。趕時間的人只讀到 in smokers 就選 drop——菸害警示奏效、吸菸人數下降，這個推論本身完全合理，錯在漏掉後面那一串。讀完整組再回頭看前一句 It has been very successful（這個做法成效非常好），方向就對上了：成效好，想戒菸的人變多，填 increase。判斷方式：空格後的名詞若帶後位修飾（分詞、介系詞片語、關係子句），一定要讀到修飾語結束再判斷。名詞的 increase 固定跟 in 連用，不是跟 of 連用。
change 雖然中性，但 a 44% change 語意含糊，讀者無法判斷是增是減，不符合宣傳文案的表達習慣；portion 是「部分、份量」，不與百分比構成 a 44% portion in 這種說法。
an increase／a decrease／a drop in（…的增加／減少／下降）、on the increase（持續增加中）、lead to（導致）、kick the habit（改掉這個習慣，在此指吸菸）。其中 lead to 這一組考過 7 個年度，88 年第 28 題 →、90 年第 22 題 →、99 年第 26 題 →、108 年第 16 題 →、110 年第 19 題 →、學測參考試卷第 23 題 →都出現過。
