SAT WR

1.((((the treaty of versailles ,which formally ended the first world war , is blamed some historiansd by some historians for the eventual outbreak of world war II .)))
A. same
B. some historians blame the treaty of versailles ,which formally ended the first world war ,as the eventual outbreak of world war II.
the right answer is A …but is the original sentence in the passive voice while B in the active voice so B is better than A??
why we choose A!!!

2.when victora woodhull A(was selected) by the equal rights party to be B(its) candidate in the 1872 election , C(she became ) the frist woman D(to run) for president of the united states.E(no error)

the right answer is E …but i believe that we must use HAD in the first event of two events SO is the choice A should be
(HAD been selected) ??!!

I have no idea what the orginal sentence is, did you copy it down wrong?
However for B,
Some historians blame the treaty of versailles ,which formally ended the first world war ,as the eventual outbreak of world war II.

Breaking it down, we see it looks like
Some historians blame blah as the eventualy outbreak

You don’t say you blame something “as” something, you say you blame something “for” something.

The first sentence has “for” so that’s why its probably right.
Although if it really were “The treaty of versailles ,which formally ended the first world war , is blamed some historiansd by some historians for the eventual outbreak of world war II.”, it wouldn’t be right.

Also as a side note, sometimes you have to use passive voice on the sat.
A lot of teachers say stuff like don’t use passive voice ever, just ignore them for the sat.
