Explanation:

1. Generally, in developing countries, a larger proportion of income is spent on food compared to developed countries. Pakistan is a developing country among the options, while the US and Japan are developed. Without specific data from the lessons, this is a general - knowledge based assumption.
2. In ancient agriculture, artificial chemicals, factory - produced fertilizers, and hydroponic systems did not exist. Irrigation using river floods like the Nile was a common method of fertilizing fields as the floodwaters carried nutrient - rich sediments.
3. Modern agriculture is characterized by a focus on efficiency, the use of advanced technology, and global connections for trade and knowledge sharing. It is less local and small - scale compared to ancient times and is highly reliant on machines rather than just animal labor.

Answer:
