Official Solution:
Under the rule of King Saif, Qatania had been the largest exporter of natural gas, which is used to produce energy worldwide. However, since his brother King Ahmet took over the power to rule Qatania, the gas export has been significantly dropping because of the depletion of existing gas wells and lack of investment in new gas wells. Nevertheless, now King Saif’s son Prince Saif II is taking back the power from King Ahmet. Prince Saif II has declared that he would increase investments in developing new gas wells, thereby boosting the gas export of the country to the levels under King Saif.
Which of the following options, if true, most significantly raises doubts about the plan of Prince Saif II?
A. Prince Saif II gained back power from Prince Ahmet through a coup, making the Prince quite unpopular among the people of Qatania.
B. Qatania has a political conflict with the neighboring natural gas exporting countries, who intend to stop all imports from Qatania.
C. Qatania does not have enough capital to invest in all the planned new gas wells and investment for some of the new gas wells will come from foriegn companies.
D. During the reign of King Ahmet, the population of Qatania has increased significantly, thereby raising the demand of energy in Qatania exorbitantly.
E. The old gas wells have not yet been completely depleted and some of them still produce considerable amounts of natural gas.
The argument of Prince Saif II is as follows:
Premise: increased investment in developing new gas wells
Effect: boost in gas export.
The correct option must attack the above link between premise and conclusion.
A. The popularity of the Prince does not bear on the premise to conclusion link described above.
B. The neighboring countries that might stop importing from Qatania are gas exporters themselves. Questions might have arised about the Prince’s plan, if the countries that import gas from Qatania stop importing from the country.
C. How the new developments will be financed have no bearing on the premise to conclusion link described above. The argument holds good irrespective of the mode of investment.
D. CORRECT. This option casts some doubt about the plan of the Prince. If the internal consumption of energy in Qatania has increased exorbitantly, then producing more natural gas may not boost export of the gas, because this additional production might be used within Qatania itself to cater to the exorbitant rise in demand for natural gas.
E. The argument is about additional production of natural gas in newly developed gas wells and export of this gas. The argument has no bearing on the gas that is already produced in the existing gas wells.
