Step 1: Understanding the Concept:
This question focuses on the history of agricultural extension, specifically looking at its origins in Europe during the 19th century.
Step 3: Detailed Explanation:
Let us evaluate each statement:
- Assertion (A): The Great Famine of Ireland (1845-1852) was caused by a potato blight outbreak (caused by the oomycete Phytophthora infestans).
Because potato was the primary food source for Irish peasants, the crop failure led to widespread starvation and distress. Thus, the assertion is correct.
- Reason (R): In response to the crisis, the Lord Lieutenant of Ireland (Lord Clarendon) established a system of traveling (itinerant) agricultural lecturers.
These instructors traveled to rural areas to teach farmers how to grow alternative crops (such as turnips and parsnips) to diversify their food supply and survive the famine. This initiative is recognized as one of the earliest structured agricultural extension programs. Thus, the reason is correct.
Now let us analyze the relationship between the two statements:
The appointment of itinerant lecturers (R) was an emergency response to the potato blight crisis. It did not cause or explain the outbreak of the blight itself (A).
Therefore, while both statements are historically correct, (R) is not the causal explanation for (A).
Step 4: Final Answer:
Both (A) and (R) are correct, but (R) is not the correct explanation of (A).
