The emission of sulfur dioxide when high-sulfur coal is burned is restricted by law. New coal-burning plants usually comply with the law by installing expensive equipment to filter sulfur dioxide from their emissions. These new plants could save money by installing instead less expensive cleaning equipment that chemically removes most sulfur from coal before combustion.
Which of the following, if known, would be most relevant to evaluating the claim above about how new coal-burning plants could save money?
原题 (by lestatwm ) Editorial in Golbindian Newspaper: For almost three months, opposition parties have been mounting daily street demonstrations in the capital in an effort to pressure the ruling party into calling an election. Though the demonstrations were well attended at first, attendance has declined steadily in recent weeks. However, the decline in attendance does not indicate that popular support for the oppositionâ?s demands is dropping, since
A. the oppositions demands have not changed during the period when the street demonstrations have been mounted. B. No foreign governments have expressed any support for the oppositions demands. C. The state-controlled media have ceased any mention of the demonstrations, leaving many citizens outside the capital with no way of knowing that demonstrations continue. D. There have not recently been any antigovernment demonstrations in cities other than the capital. E. A recent sharp decrease in unemployment has led to increased popular support for the government.

Which of the following, if known, would be most relevant to evaluating the claim above about how new coal-burning plants could save money?
A. Whether existing oil-burning plants are required to filter sulfur dioxide from their emissions B. Whether the expense of installing the cleaning equipment in a new plant is less than the expense of installing the cleaning equipment in an older plant C. Whether the process of cleaning the coal is more expensive than the process of filtering the emissions D. Whether lawful emissions of sulfur dioxide from coal-burning plants are damaging the environment E. Whether existing plants that use the filtering equipment could replace this equipment with the cleaning equipment and still compete with new plants that install the cleaning equipment
Editorial in Golbindian Newspaper: For almost three months, opposition parties have been mounting daily street demonstrations in the capital in an effort to pressure the ruling party into calling an election.

There have not recently been any antigovernment demonstrations in cities other than the capital. E. A recent sharp decrease in unemployment has led to increased popular support for the government.
Situation: Since three months there are demonstrations in the capital city to arrange a reelection. However, there are currently declining attendee numbers.
Analysis: why is the declining of attendees in number not a sufficient cause for the drop of support for the opposition parties' demands? Any reasonable explanations that the decline is not actually a decline make the occurrence logical.
A. Whether the oppositions demands have changes during the mounted period has no bearing on the situation when the attendance is not crowed. B. Foreign governments' attitude is irrelevant. C. Correct. The support for the oppositions demands has not changed because the attendance on the demos does not reveal the support. D. Irrelevant. E. Unemployment is not an issue in this argument.
