Air travel has become more affordable over the past few years. The entry of low-cost carriers into the market has significantly accelerated this trend. As a result, airports like Los Angeles International Airport (LAX) have seen a considerable increase in passenger traffic, even during traditionally less busy months. Consequently, the government has had to improve the amenities at these airports. The Department of Transportation should prioritize increasing flight frequency and enhancing facilities at airports nationwide to better accommodate the needs of passengers.
Which of the following assumptions does the argument depend on?Air travel is getting cheaper, low cost carriers have increased demand, airports like LAX are busier even in slow months, and therefore the government should improve airport facilities and flight frequency nationwide.
A. Gas prices would drop further and boost the industry, thereby increasing the need for better airports nationwide.
This talks about gas prices dropping further. The argument never relies on fuel prices changing in the future, so this is not required for the conclusion. Not an assumption.
B. The growing global trend of air travel will soon be reflected in the United States.
This is about a global trend reaching the US. The passage already talks specifically about US airports like LAX, so it does not need global trends to support the recommendation. Not an assumption.
C. All airports across the country will experience the same level of increase in air travel demand.
This says all airports will see the same increase. The argument does not require uniform growth everywhere, only that growth is happening broadly enough to justify nationwide action. Too strong and unnecessary.
D. The growth in the air travel industry will continue across the country in the coming years.
The argument assumes that the growth in air travel will continue across the country. Without this, expanding facilities and increasing flight frequency nationwide would not make sense. This is the
key hidden assumption the recommendation depends on.
E. A higher number of air travelers will lead to increased competition for quality service, which includes better frequency, meal selection on board, and friendly staff.
This adds extra ideas about service quality like meals and staff. The argument is about capacity and facilities, not service competition. Irrelevant to the logic.
Answer: (D)
