For fourth class building the doors and windows shall be of _________ wood or country wood.

For fourth class building the doors and windows shall be of _________ wood or country wood. Correct Answer Mango

Technically mango is a hardwood with dense grains, so it has the strength to bear the weight necessary for chairs and heavy tables, but it’s still soft enough that it’s relatively easy to work with, requiring no special tools on behalf of the manufacturers. Mango furniture can stand the wear and tear of time as well as your grandmother’s oak kitchen table, but, unlike traditional hardwood furniture, it’s more affordable and, as we’ll get into, completely sustainable.

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?
