  I found this one tricky too and thought about it for awhile. Remember this is a Necessary Assumption question. You're only looking for something that has to be true for the argument to be true. E doesn't have to be true to make the argument true. Try the negation method. If you negate E does it wreck the argument?
  
  Negate Answer Choice E: Parts made for cars in our country are poorly constructed.
  
  If parts are made in this country are poorly constructed it doesn't necessarily wreck the argument--they could still be better constructed than the foreign cars. You don't know what is necessarily true.
  
  Try Negating Answer Choice Parts that satisfy our government standards are as poorly constructed as cheap foreign made parts.
  
  The argument is wrecked. Why? Because Clarks parts satisfy government standards---which means if we negate this answer choice it would mean that Clarks parts are just as poorly constructed as the foreign made parts. So why prefer them?
