With their plan 12 by the rain, the two dozen participants squeezed into the living room.
答案：(B) disrupted
with 獨立分詞構句，With their plan disrupted by the rain（他們的計畫被雨打亂了），過去分詞 disrupted 表被動；facilitated（被促進，語意相反）、disclosed（被揭露）、fulfilled（被實現，語意相反）都不合。
看到 With their plan ___ by the rain，你可能先卡在 with 上：with 不是「和」嗎，怎麼後面接一長串？這裡的 with 是「附帶狀況」用法，With ＋ 受詞 ＋ 過去分詞，表示「在……被……的情況下」。四個選項都是過去分詞，形式上都塞得進去，所以真正要比的是意思。
前一句 Unfortunately, it started pouring.（很不巧，下起了傾盆大雨），Unfortunately 這個副詞已經定調接下來是壞消息。後半句 the two dozen participants squeezed into the living room（二十多人擠進客廳）也說明原訂在花園的討論泡湯了。所以空格要填「被打亂、被中斷」——disrupt 指的正是擾亂、中斷原本進行中或計畫好的事。
facilitated（被促進）與 fulfilled（被實現）方向完全相反，計畫如果順利，就不必擠進客廳；disclosed（被揭露）的受詞通常是祕密或資料（disclose information），計畫被「揭露」跟下雨也接不上因果。
with ＋ 受詞 ＋ 過去分詞（在……被……的情況下）、disrupt the plan／traffic（打亂計畫／交通）、disruption（中斷、擾亂）、facilitate communication（促進溝通）、disclose information（揭露資訊）、fulfill a promise（實現承諾）、squeeze into（擠進）。
In 1995, a group of business and academic leaders met at the home of Juanita Brown and David Isaacs in Mill Valley, California. None of them had any idea they were about to create a social innovation that 11 rapidly around the world.
The group was supposed to have a large-circle discussion in their beautiful garden. Unfortunately, it started pouring. With their plan 12 by the rain, the two dozen participants squeezed into the living room. They broke into small, intimate table conversations, recording their insights on paper tablecloths. They periodically stopped their conversations to switch tables so the insights and ideas might 13 and deepen. As they moved from one table to another, they noticed new ideas emerging from the discussions. This in turn enriched subsequent rounds of conversation.
Over the course of the morning, the innovative discussion process 14 a new form of collective effort that transformed the depth, scope, and quality of their discussion. The World Café was 15 created. Since that rainy morning in Mill Valley, the World Café approach has been applied to multi-group discussions and cooperative actions by businesses, industries, and educational institutions around the world.
