Choice E says - The development of a safe and durable material for pipes has made repairing lead water main pipes more costly and less practical than replacing them.

So, this means that we have another option available (the option of safe and durable material) than to keep on repairing the lead water pipes. The development of this new material has made repairing lead water pipes more costly implies that the new material is cheaper to use and thus, it is less practical to keep on repairing the existing lead pipes. Thus, it is far better to use the new material which will in turn bring in reduction in training costs pertaining to repairing lead pipes.

Hope the information helps. All the best to you and happy studying!
