worst options
e - over 75 % of x in France .... compared with over 33 % in Germany (u compare % with % not % with energy) - out
d - change of meaning (just over 333% is more than 33%) - out
b - energy derived means produced not spent (change of meaning) - out
so it between a and c
in a) it can refer to energy produced or to nuclear power
so c for me whats the OA pls
Thanks for that Chix
