According to the speaker, why did Hudson river sloops have tall masts?
【解题思路】
1．四项均为以to引导的不定式短语，表目的。To后面所接的动词中，两项为allow，一项为catch，一项为add。
2．两项提及sails(风帆)。
结论：本题可能与做某事的目的有关，需留意与风帆有关的信息。
【解析】短文中部指出：the mast was very tall，in many cases over 100 feet tall，so that the large sails could，catch winds blowing above the shore line hills．为了适应哈德逊河特殊的水文环境，荷兰人设计了一种单桅帆船，这种船有一桅两帆，一帆在桅前，一帆在桅后，很多时候，桅杆高达100英尺，这样就可以利用到从岸旁的山顶上吹过来的风。故选B。
