Official UPSC Format

Consider the following statements:
Statement I:
Of the two major ethanol producers in the world, i.e., Brazil and the United States of America, the former produces more ethanol than the latter.
Statement II:
Unlike in the United States of America where corn is the principal feedstock for ethanol production, sugarcane is the principal feedstock for ethanol production in Brazil.
Which of the statements given above are correct?

1. Statement I: Of the two major ethanol producers in the world, i.e., Brazil and the United States of America, the former produces more ethanol than the latter.

2. Statement II: Unlike in the United States of America where corn is the principal feedstock for ethanol production, sugarcane is the principal feedstock for ethanol production in Brazil.

⚡ Quick Recall Snippet

Global biofuel production relies on different agricultural feedstocks based on geography. The United States is the world's leading ethanol producer, primarily fermenting corn. Brazil ranks second globally, utilizing its massive sugarcane industry as feedstock.

Correct Answer is Option D
According to the International Energy Agency (IEA) Biofuels Data, global ethanol production is dominated by the US and Brazil, but they utilize entirely different agricultural sectors.
  • Statement I is Incorrect: While Brazil is a massive pioneer in biofuel usage, the United States of America is actually the undisputed largest producer of ethanol by sheer volume globally, outputting significantly more billion gallons annually than Brazil.

  • Statement II is Correct: The agricultural base (feedstock) for this production differs drastically due to agro-climatic conditions. The United States relies overwhelmingly on starch-heavy corn grown in the Midwest. Conversely, Brazil's tropical climate supports massive plantations of sugarcane, which is their principal and highly energy-efficient feedstock for ethanol.

    • 🚨 The Examiner's Trap

    Brazil is incredibly famous for pioneering the widespread use of ethanol as fuel (flex-fuel vehicles) since the 1970s. Because Brazil's domestic economy is so visibly reliant on ethanol, students falsely assume they must produce more total volume than the US.
