The first question asks which party's members are most likely to vote according to their stated preference (i.e. if they said they were for it, they vote for it, and if they said they were against it, they vote against it.) The y-axis shows the probability of a vote matching the stated preference. For people who are against the issue, Zeta is the party that is most likely to vote according to that position (at about 70%). However, we see a sharp decrease as we move towards people who are for the issue (where there is under a 50% chance for Zeta voters against the issue to vote against the issue). The Delta party is much more consistent, ranging from 60% (for voters who are against the issue) to just over 80% (for voters who are for the issue).

The second question is only concerned with the "against" column, and as we saw in the first question, Zeta voters are most likely to vote according to their "against" preference.

Thanks a lot bill.Much appreciated!
So all we need is to use the probability on the y-axis.
what I thought was the political party which is stagnant over the period would be the right answer for it(in the graph the one with a straight line-that would be SIGMA here),but my bad, the answer was wrong.

Because for delta-the probability would be 0.6 to 0.8
While for sigma it is between 0.5 and 0.6 throughout (i.e for and against aswell)

Can you please explain where did I go wrong?
