I find these questionairres puzzling because they rely so heavily upon completely charged, partial, and partisan statements. More importantly, these statements are taken from broader sets of political, ideological, and social discourses, and, so far as I can tell, the question is often trying hardest to see whether you recognise and are comfortable with that discourse. That is, they aren't actually asking you to reject or accept putative statements of fact or truth - even though this is the form the actual questions take. Instead, they are checking to see whether the statement resonates with you.
But the difference between these two modes of discourse (truth and resonance) creates some dilemmas. Thus, what to make of this question?
A significant advantage of a one-party state is that it avoids all the arguments that delay progress in a democratic political system.
You see, I count myself as something of a radical democrat; in almost every case, I'll favour democracy. But faced with answering whether the above statement is true or not, what do I do? Because,...well, yes, 'I agree' (I even strongly agree) that the above statement is true: a one party state does get things done. I'm not a big fan o the things it 'gets done', but it certainly gets them done.
If the question were: do you favour the liberty afforded by radical, particapatory democracy over the efficient decision-making of more authoritarian forms of government, then I can easily answer in a way that probably tells them what they want to know. But they don't want to ask questions like that.
Now, what does this tell us about the current state of society, politics, etc.? I haven't figured that one out yet. But the fact that they aren't really asking you direction questions but instead trying to tap into discourses in this way....I think that might be significant.
