Understanding the Passage and Blank 2

The passage describes Ragi, a plant known for its nutritional value. It highlights that Ragi is packed with healthy nutrients and mentions specific components like iron, protein, and calcium. We need to fill in the blank in the sentence: "It is a good (2) _______ of iron, protein, calcium and (3) ________ minerals." This sentence indicates that Ragi provides these nutrients.

Analyzing the Options for Blank 2

Let's look at the provided options for blank number 2 and consider how each word fits into the sentence:

• origin: This refers to the point where something begins or arises. While Ragi has an origin (where it is grown), Ragi itself is not the "origin" of the nutrients in the sense of their creation, but rather where we get them from.
• source: This refers to a place, person, or thing from which something comes or can be obtained. If Ragi provides iron, protein, and calcium, it serves as a place or thing from which these nutrients are obtained. This fits the context well.
• spring: This word typically refers to a season, a coil, or a natural flow of water from the ground. None of these meanings fit the context of Ragi providing nutrients.
• cause: This refers to a reason or motive for an action or event. Ragi is not the "cause" of iron, protein, or calcium; it contains and supplies them.

Why 'Source' is the Correct Fit for Ragi's Nutrients

When we talk about where we get something like nutrients, vitamins, or information, the word "source" is commonly used. For example, milk is a source of calcium, and sunlight is a source of Vitamin D. In the given sentence, Ragi provides iron, protein, and calcium, meaning it is a place from which these nutrients are obtained. Therefore, Ragi is a good source of these nutrients.

Comparing the options, "source" is the only word that correctly describes something that provides or contains essential components like nutrients in this context.

Evaluating Option Suitability for Blank 2

Based on the analysis, the most appropriate option to fill blank number 2 is "source". The completed phrase would be "It is a good source of iron, protein, calcium...".

Additional Information on Nutritional Sources

Understanding the term "source" in a nutritional context is key. A food item is called a good source of a nutrient if it provides a significant amount of that nutrient in a serving. Different foods are sources of different nutrients. For example:

• Citrus fruits are a good source of Vitamin C.
• Dairy products are often cited as a good source of calcium.
• Lentils and beans are good sources of protein and fibre.

Identifying the nutritional sources in your diet is important for maintaining a balanced and healthy intake of essential vitamins and minerals.
