标题: GWD19-27疑问

Scientists have identified an asteroid, 2000 BF19, that is about half a mile wide and, if it strikes Earth, it can do tremendous damage to part of the planet but probably not cause planetwide destruction.

and, if it strikes Earth, it can do tremendous damage to part of the planet but
and, if it would strike Earth, part of the planet could experience a tremendous amount of damage but it would
and that, if it were to strike Earth, could do tremendous damage to part of the planet but would
and that, if Earth is struck by it, can do part of the planet tremendous damage, but it would
and that, if it strikes Earth, it could experience a tremendous amount of damage but

答案是C，我也觉得虚拟语气在这里会比较好，但我有些疑问：could do tremendous damage的主语是不是应该是that，而that指代it were to strike Earth，如果是这样，that 可以这样指代一个句子么？

could do tremendous damage的主语是不是应该是that

对的

that指代it were to strike Earth

这个就不对了，that这里和前面的that并列，表定语从句：）
