如果把B选项的is改成are,是否就对了?对于大全对B的解释:presenting the object of the verb subject as a phrase beginning with how and ending with the verb interact produces a sentence that seems to be about how various conditions react to detailed scrutiny from space. 我不是很明白~
跟E比B改了还是觉得不对,which和that的逻辑意思上还是有不同的 Mahattan里说 when the relative clasuse add non-essential information rather than identifying the noun it follows,"which" is used and is preceded by a comma when the relative clause identifies the noun it follows with essential information rather than adding incremental information,"that" is used without a comma. 我觉得that从句解释说明satellites, 不是non-essential info, 如果换了句子中心有变化
