can any body tell me what its is referring in a,b,c,d ... I think it is dangling .. second thing all a,b,c,d acts as a modifier so China should be followed by comma , which is not there . So I think e should be correct ..
I think in b, c , and e , which creates ambiguity . It 's not clear whether it refers to demand or "increasing supplyand lowering prices" . Out of a and d .. 'in' used in sentence a looks better and d has being so I would prefer a as answer ... thanks
I think C is correct becasue here it says 4 times as good as .... we are comparing similar thing in this . so as is more appropriate comapred to than ....
