Read the following excerpt carefully.

Which of the following sentences will MOST logically complete the above excerpt?
- Germany unsuccessfully experimented with trains fuelled by hydrogen.
- The impact of such a change in the energy system would be huge, potentially generating $2,500 billion in revenue globally and creating more than 30 million jobs.
- Earlier, experts thought that hydrogen fuel would be too expensive.
- Hydrogen can be made through reformation, electrolysis, or pyrolysis, comes labelled in different colours from simple green to more complicated turquoise, can be stored as a gas, cryogenic liquid, converted to ammonia or even borane and then finally made useful through a fuel cell, engine, or burner.
- Despite the potential, 90% of the general population knew nothing about hydrogen technology.
The Correct Option is B
Solution and Explanation
To complete a paragraph, understand the overall theme and flow of ideas of the paragraph and focus on the last line. Here, the theme is that hydrogen will be an important part of our future. The last line talks of the results of the McKinsey study on the increasing use of hydrogen in the future. So, the logical extension of the paragraph is to expand on the same theme. The last line says ‘18% of global energy consumption and reduce carbon dioxide emissions from current levels by some 6 gigatons’. And the next line would logically talk about the effect of this change.
Option E looks correct but the tense is different and the general population’s awareness of the importance of hydrogen is out of scope of the passage.
Hence, B is the correct answer.

(2)_. The relation of support between premises and conclusion can be cashed out in different ways: the premises may guarantee the truth of the conclusion, or make its truth more probable; the premises may imply the conclusion; the premises may make the conclusion more acceptable (or assertible).(3)__.
