“The green revolution has won a temporary success in man's war against hunger and deprivation; it has given man a breathing space. If fully implemented, the revolution can provide sufficient food for sustenance during the next three decades. But the frightening power of human reproduction must also be tamed; otherwise the success of the green revolution will be only ephemeral.”

— Norman Borlaug, agricultural scientist, Nobel Lecture, 1970

Based on the passage and your knowledge of world history, which of the following was a primary technological innovation of the Green Revolution that led to the increased food production described by Borlaug?

  1. The breeding of high-yielding, disease-resistant crop varieties combined with the use of synthetic fertilizers and pesticidesCevap
  2. B
    The implementation of eco-friendly farming practices and organic composting to restore natural soil biodiversity
  3. C
    The global transfer of American food crop species such as maize and potatoes to Afro-Eurasian agricultural systems
  4. D
    The creation of state-controlled cash crop plantations managed directly by European colonial administrations

Cevap

The breeding of high-yielding, disease-resistant crop varieties combined with the use of synthetic fertilizers and pesticides
The correct option is correct because the Green Revolution in the mid-to-late twentieth century achieved massive increases in crop yields through the cultivation of scientifically developed high-yielding varieties of grain (such as dwarf wheat and rice) and the heavy application of synthetic fertilizers, chemical pesticides, and advanced irrigation.

Adım Adım Çözüm

1
Analyze the stimulus context and the question stem.
The stimulus discusses Norman Borlaug's speech on the success of the Green Revolution in increasing food production.
This establishes the historical period (mid-to-late 20th century) and the subject (agricultural changes of the Green Revolution).
2
Identify the primary technological drivers of the Green Revolution.
The Green Revolution was driven by the development of high-yielding varieties (HYVs) of grains, chemically synthesized fertilizers, herbicides, pesticides, and modernized irrigation systems.
This distinguishes it from other historical agricultural developments and helps identify the correct option.
3
Evaluate the choices to find the one that accurately describes these technological innovations.
The option containing high-yielding crop varieties and synthetic inputs matches the core technologies, while other choices describe unrelated historical events like the Columbian Exchange or misinterpret the revolution as eco-friendly/organic farming.
This confirms the correct option based on historical facts and eliminates distractors.

Anahtar Kavram

The Green Revolution utilized scientific advancements in crop breeding and chemical inputs to rapidly increase global food production in the mid-to-late twentieth century.
