A.in which B.that
因为是同位语从句,那为什么不能看成是定语从句呢,in the announcement不是也可以吗

选择B
A recent announcement by 《《scientists that they have successfully cloned the first human embryo》》 has caused much debat.
明白了吗?
再问： = =我没明白怎么办
再答： that they have successfully cloned the first human embryo 这些是给scientists作定语的，用来限定scientists的，明白了吗？不明白？
