I dont know is your papers main idea stated clearly?
Answer:
The options a)- A blast furnace is used and d)-Coke is used to produce the heat are FALSE.
Explanation:
Aluminium is a chemical element and the most abundant metal present in the Earth's crust. An aluminium ore is called bauxite. Aluminium is extracted from its ore by the process of electrolysis, called the Hall–Héroult process. The extraction of aluminium is an expensive process as it requires large amount of electricity. The bauxite is purified to produce aluminium oxide. Then, aluminium is extracted from the aluminium oxide.
<u>Therefore, the refining of aluminum from its ore does not involve the use of a blast furnace and coke to produce heat.</u>

According to plumbing regulations, every home must have a minimum of one toilet, one bathroom sink, one bathtub or shower, and one kitchen sink. Fixtures include items like these and a few more things mentioned in this chapter.
When choosing fixtures, consider flow rates, volume, and water usage. Water saving is a major concern of plumbing sustainability. Two key areas for water conservation are shower heads and bathroom faucets. The length of each use determines how much water is actually saved when taking a shower. A handheld shower may have controls that allow the water flow to be turned off while performing specific showering tasks, including lathering.
