Reading Comprehension

Aviation knits the United States together, improves the quality of Americans' lives, and helps to enhance national security. Yet the explosive growth of aviation over the last several decades has brought with it a set of pressing challenges, which include increasing congestion within the nation's airspace system and the increased negative impact of aviation on the environment.

The increasing congestion of the nation's airspace system is the product of concurrent forces; while the increasingly global economy creates enormous numbers of jobs that require frequent long-distance travel, the decreasing cost of air travel and the introduction of low-cost airlines increases the number of non-business flights. Improperly managed congested air spaces result in restricted flight paths, delayed takeoffs and landings, and even a moderately heightened risk of aircraft collisions. However, ongoing research into aircraft clustering, airspace complexity and improved pilot-controller communication will lead to the development of new technologies to mitigate risk and expand airspace capacities.

Greenhouse gas emissions constitute the primary negative impact of aviation on the environment. National Aeronautics and Space Administration (NASA) investigators are working to develop satellite-based navigation systems that would allow for more direct routing of aircraft, which would in turn improve fuel efficiency and reduce carbon dioxide output from planes. According to the Federal Aviation Administration (FAA), the full implementation of such technology could reduce greenhouse gas emissions from aircraft by up to 12 percent by 2025.

A decrease in government funding for research on airspace congestion and greenhouse gas emissions generated by aircraft, however, is making it increasingly difficult to maintain research programs. Bringing research to maturity requires a greater level of investment than legislators have been willing to make. This needs to change. If promising technologies and operational concepts are not developed to a point where they can be applied to actual situations, the nation will never receive the full benefit of the significant investment devoted to the research conducted thus far.


It can be inferred from the passage that which of the following is true of funding for research on airspace congestion and greenhouse gas emissions?

A it has been cut to fund research on other issues
B a significant portion comes from the government
C the majority of funding comes through NASA
D its continuation is contingent upon the implementation of new technologies
E more funding goes to research on greenhouse gas emissions than to research on airspace congestion

I think D is the correct answer. we can refer the last sentence of last paragraph.

I feel the answer is B.

B a significant portion comes from the government.

A decrease in government funding for research on airspace congestion and greenhouse gas emissions generated by aircraft, however, is making it increasingly difficult to maintain research programs. Bringing research to maturity requires a greater level of investment than legislators have been willing to make.

I interpret it as earlier there was a significant amount of funding coming from government and now
A decrease in government funding...........

The lines I have put on bold fortify my belief in B.

Can someone send the correct answer.

IMO B

IMO, B. Using Elimination Strategy.

D too. Sentence starting at the 5th last line gives the clue.

I will go with B too....By POE

I think D.

The only way reseach can continue is from funding by the government, true. However, that does not mean a SIGNIFICANT portion of the funding is from the government.

What is true is that for the research to continue, they need to apply technologies to actual situations. The government decreasing their funding is stopping them from funding this application, but the passage does not mention how significant this funding is.

B


because "A decrease in government funding for research on airspace congestion and greenhouse gas emissions .... is making it increasingly difficult to maintain research programs".

This statement mans that the government funding is indeed a significant portion for the researches to be carried out

I would go for B as well.

oa is B

great guys thanks for bearing

oa is B

great guys thanks for bearing

Reason why B is CORRECT: A decrease in government funding for research on airspace congestion and greenhouse gas emissions is making it difficult to maintain research programs.

Reason why D is INCORRECT: D says continuation is dependent in implementation of NEW TECHNOLOGIES. These new technologies are nowhere mentioned in passage and the promising technologies which are referred in last sentence of passage is referring to technologies for airspace congestion & greenhouse gas, NOT TO ANY NEW TECHNOLOGIES

The key to getting this q rite is knowing the the meaning of contingent
