試題分析：句意：你知道這個(gè)殘疾人是如何成功地運(yùn)營(yíng)這么一個(gè)大公司的嗎？我不知道，但是我想，他肯定經(jīng)歷了許多困難。問(wèn)句中succeeded用的是過(guò)去時(shí)，可知答句中應(yīng)該是對(duì)過(guò)去情況的推測(cè)。A、B兩個(gè)選項(xiàng)都可表示對(duì)過(guò)去情況的推測(cè)，但A選項(xiàng)的語(yǔ)氣很弱，意為：也許經(jīng)歷了不少困難吧。而根據(jù)問(wèn)句中所說(shuō)的殘疾人成功運(yùn)營(yíng)大公司，應(yīng)該推斷他肯定經(jīng)歷了不少困難。故選B。
