GMAT Reading Comprehension (RC) | Re: Although recent censure of corporate boards

Hi,

I knew the ans of the second question was hidden into the line 'At times, despite disappointing corporate performance, compensation of chief executive officers reaches indefensibly high levels, nevertheless, suggestionsthat the government should legislate board reform are premature . There are ample opportunities for boards themselves to improve corporate performance.'

But I did not understand how optionE. Corporate boards themselves could act to make such legislation unnecessary.
