Answer 1

that...to loud noises for a long time will slow the deverlopment of speech in ba babies是宾语从句，being exposed to loud noises for a long time（长期处于嘈杂的环境中）是从句的主语。
分词不能做主语，只有名词、代词、名词性短语、从句才可以做主语。排除B。
being exposed 与动作的执行者是被动关系，被动语态的结构是“be+过去分词”，在非谓语动词中去掉be。排除A。
having exposed是主动语态的现在完成时在非谓语动词中的表现形式。排除D。

第二题选C。measure在这里作不及物动词， 有...长(或阔、高等) 。
measuing about 6400 kilometers,是现在分词短语作状语，表示伴随情况。
