Question

Hard water is defined as having high concentrations of dissolved calcium and magnesium, which are found naturally in materials like limestone, magnesite, gypsum, and other minerals that groundwater comes into contact with.

Calcium is essential for healthy bones and teeth. It also plays a role in blood clotting, appropriate muscle function, and heart rate regulation. Magnesium is required for over 300 biochemical processes in the body, including blood pressure regulation, heart rate regulation, protein synthesis, and blood sugar regulation.
Scientists have documented the importance of hard water since the 1920s. One study examined the effects of dietary magnesium on rat survival rates. The below is a summary of data from the study.

A lot of homeowners now routinely soften their water. To prevent the accumulation of a residue known as scale in pipes and appliances, soft water has had the calcium, magnesium, and other minerals removedSoaps and detergents work better in soft water as well.
Studies on the health advantages of drinking hard water indicate that those who live in areas with low dissolved calcium and magnesium levels may be more susceptible to specific illnesses.

The table below is a summary of data from two human populations that examined the role of dietary magnesium on cardiovascular health

Scientists claim that levels of dietary calcium and magnesium intake can affect the health of an organism.

Which statement best explains the central idea of the passage above?

Answers

People who live in rural environments are healthier than people who live in urban environments.
Softening water results to the loss of minerals, and as such people should stop softening hard water.
correct

People may experience health benefits from drinking hard water because it contains magnesium.
Individuals consuming higher amounts of calcium have better health compared to that that don’t.

Explanation

The main idea of the investigator is that drinking hard water has several health benefits. In the first paragraph, the investigator offers several beneficial benefits that the body may accrue by individuals taking hard water. The paragraph also outlines several studies that have shown the benefits of magnesium in supporting the health of human beings.
