4. How do paragraphs 12-14 contribute to the
development of ideas in the text? Select TWO
answers.
O A They explain that humans obtain essential
nutrients from food.
B They identify which nutrients humans are
commonly deficient in.
OC They encourage the practices of eating fish and
vegetarian diets.
OD They support the idea that healthy soil may be
necessary for proper human nutrition,
E They suggest that fish provide humans with
different essential nutrients than plants.
OF They list and provide details about the nutrients
humans cannot produce naturally,

The paragraphs show that humans obtain essential nutrients from food especially in paragraph 13 where it is shown that there is an increased link between human health and nutrition. Nutrients like carbohydrates, antioxidants and saturated fat content help in the regulation of the immune system which is a very important system thereby making these nutrients essential.

They also support the idea that healthy soil may be necessary for proper human nutrition because they show that some nutrients can only be produced as a result of ingesting certain plant-like organisms which were rich in the requisite nutrients. The organisms only get these requisite nutrients from the soil so maintaining healthy spoil that can give plants nutrients may be necessary for human nutrition.
