I guest the Blank A is "Authori...." and Blank B should be "Elec...".

From my understanding, IN FACT acts as a function that Alters the meaning of the previous sentence, the previous sentence comes with a positive meaning, (for example, the Blank A answer, authori.....) so, we need to find fil "Elec..." for Blank B.

By the wat, i did not have a cue that which book comes more value for the preparation of GRE. I am now doing 陈圣元 and feel so good .
