...the Committee advocates fair trade and 12 pricing for goods and services.
答案：(C) reasonable
reasonable pricing（合理定價）表示委員會提倡公平交易與商品服務的合理定價；prominent／essential／intensive 均不符合此處語意。
reasonable 你的印象大概是形容人的「講理的、通情達理的」，像 a reasonable person。它用在價格上時意思是價格公道、不會太貴，a reasonable price 是很高頻的說法。同一個字，形容人與形容價錢是兩種都常考的用法。
四個選項都是形容詞，文法上都修飾得了 pricing，可見這一格考的是語意。線索在 and 的前面：the Committee advocates fair trade and ___ pricing（該委員會倡導公平交易與……的定價）。and 把兩個受詞並列，兩邊的語意方向要一致。fair trade 講的是交易要公平，那麼定價自然也要走同一個方向，也就是公道、合理。並列結構不只形態要對等，語意類別也要同一類，這一題考的正是後者。
prominent（顯著的、傑出的）用來講地位或能見度，不會拿來形容定價。essential（必要的、不可或缺的）代進去變成必要的定價，價格本身沒有必不必要的問題。intensive（密集的、強化的）用在課程、訓練或農業上，像 an intensive course，與價格無關。鑑別度高達 68，是本批最高的一題，分開的是有沒有把 fair 當成線索——讀到 fair trade 就知道空格要同向，一步定案；沒讀到的人只能在四個形容詞裡憑印象挑。
a reasonable price（合理的價格）、fair trade（公平交易）、advocate（倡導、主張）、prominent（顯著的、傑出的）、an intensive course（密集課程）、goods and services（商品與服務）
