About 50 percent of all British party members are female (in contrast to only about 25 percent in Germany) but only 9.2 percent are represented in parliament.
Half of all British party members are male. 
The text says 50 percent of all British party members are female - which means the other half are male. I think the computer was fooled because I said half (which is 50%), and I said male (the opposite of female)
