Historically, the production of wood charcoal in locations where there is an abundance of wood dates back to a very ancient period, and generally consists of piling billets of wood on their ends so as to form a conical pile, openings being left at the bottom to admit air, with a central shaft to serve as a flue. The whole pile is covered with turf or moistened clay. The firing is begun at the bottom of the flue, and gradually spreads outwards and upwards. The success of the operation depends upon the rate of the combustion. Under average conditions, 100 parts of wood yield about 60 parts by volume, or 25 parts by weight, of charcoal; small-scale production on the spot often yields only about 50%, while large-scale became efficient to about 90% even by the seventeenth century. The modern process of carbonizing wood, either in small pieces or as sawdust in cast iron retorts, is extensively practiced where wood is scarce, and also for the recovery of valuable byproducts (wood spirit, pyroligneous acid, wood tar), which the process permits. The information given, if accurate, most strongly supports which of the following?

In this question a passage and a statement related to it have been given. Read carefully the passage and review the statement based on it. When Shah Jahan gave his love for Mumtaz, he would have believed that the river would continue to flow. There was no solid land on which the foundation could be laid. Therefore, to reduce the level of water, he used an engineering system to use the foundation of deep well and it was filled with stone and mud. Finally, he covered them with wooden box work structure and the tomb Made Yamuna is an integral part of the creation of the Taj and there was no such predict ion that it would dry up or become narrow. But the river was narrow and it became contaminated. The timber of wood is likely to be brittle or disintegrated as the venetian made on the foundation of wood, indicates that when the wood is submerged in the wood, the age of the wood increases. When the wood does not come in contact with oxygen, then that But such creatures cannot be found who destroy them. Due to the dryness and contamination of the Yamuna, the breakdown of a wooden tree can break. Statement. To maintain the structure of the TajMahal, a revival of Yamuna river is necessary.
