Question

A. Experts such as Larry Burns, head of research at GM, reckon that only such a full hearted leap will allow the world to cope with the mass motorization that will one day come to China or India.
B. But once hydrogen is being produced from biomass or extracted from underground coal or made from water, using nuclear or renewable electricity, the way will be open for a huge reduction in carbon emissions from the whole system.
C. In theory, once all the bugs have been sorted out, fuel cells should deliver better total fuel economy than any existing engines.
D. That is twice as good as the internal combustion engine, but only five percentage points better than a diesel hybrid.
E. Allowing for the resources needed to extract hydrogen from hydrocarbon, oil coal or gas, the fuel cell has an efficiency of 30%.

• A. CDEBA
• B. CEBDAB
• C. CEBDA
• D. ADBCE

Hint:

Look for the key statement or argument in the opening sentence and ensure subsequent sentences provide supporting information in a logical flow.

Answer 1

The Correct Option is C

The correct sequence begins with the introduction of Larry Burns’ statement about the need for a full-hearted leap to address mass motorization. Then, the benefits of hydrogen production and fuel cell technology are explained, followed by the potential of hydrogen fuel cells to deliver better economy and efficiency. The final part addresses the environmental impact and potential energy resources. Thus, the correct order is: \[ \boxed{(3) \ \text{CEBDA}} \]
