• 
  
  Let's go through these a little bit.
  我们再进一步来分析
• 
  
  So it turns out that the very first one,
  首相想到的就是
• 
  
  voters are not evenly distributed is certainly true,
  现实中选民是不均匀分布的
• 
  
  it's undoubtedly true.
  这的确是毋庸置疑的
• 
  
  But it turns out that
  但事实上
• 
  
  if you make the voters distributed more realistically,
  就算我们让选民分布更符合实际情况
• 
  
  let's say like on a bell-curve shape,
  比如说是按钟形分布的
• 
  
  it makes actually no difference to the result at all.
  但这实际上对结果没有什么影响
• 
  
  So this is true,
  纵使它是现实
• 
  
  but it doesn't actually change the result.
  但它对结果没有影响
• 
  
  So on this one we're okay.
  我们就可以说这个是次要条件
• 
  
  The result survives this change.
  因为它的变化不会引起结果的改变
