Chapter 7: Problem 23

A farmer ploughs his field, to (1) prevent the escape of moisture, present in the surface of field (2) increase the evaporation of water from the surface of field (3) make the land dry (4) None of the above

Short Answer

Expert verified

Answer: The primary purpose of a farmer ploughing their field is to prevent the escape of moisture.

Step by step solution

Analyze Option (1) - Prevent the escape of moisture

When a farmer ploughs their field, they are turning over the soil. This can help to keep moisture in the soil, as it covers the top layer of soil with a new layer that has not been exposed to sunlight or air. This reduces the amount of moisture that can evaporate into the air, helping to maintain good growing conditions for plants. So, this option seems like a plausible reason for ploughing.

Analyze Option (2) - Increase the evaporation of water

Increasing the evaporation of water from the surface of the field is not the primary purpose of ploughing. Ploughing may cause some temporary evaporation as the newly exposed soil dries out, but this is a side-effect rather than the main goal of ploughing. In fact, retaining moisture, as discussed in step 1, is more beneficial for plant growth.

Analyze Option (3) - Make the land dry

Making the land dry is not the purpose of ploughing a field. Dry soil is not ideal for plant growth as it lacks the necessary moisture for seeds to germinate and for plants to access nutrients. Therefore, this option does not accurately describe the reason behind ploughing.

Analyze Option (4) - None of the above

Before considering this option, we must analyze the other options to determine if any of them accurately describes the purpose of ploughing a field. Option (1) seems plausible, while options (2) and (3) do not appear to be correct. Since at least one option appears to be accurate, we can discard option (4) as the correct answer.

Determine the correct answer

After going through the process of analyzing each option, it becomes clear that the most accurate reason for a farmer to plough their field is to prevent the escape of moisture, present in the surface of the field. As a result, the correct answer is option (1).
