a they can be used many times or used only once
b they can be used many times, used only once, or not used at all
c they must all be used, but not necessarily in order
d they must all be used in order

Explanation:

For Question 13: Providing flights to major cities can increase passenger demand and revenue. Adding more seats can boost ticket - sales revenue. Negotiating for better prices on fuel and equipment reduces costs. Using smaller planes on less - popular routes optimizes resource use and reduces costs. Leasing to the military for secret missions is not a common profit - maximizing strategy for commercial airlines.
For Question 16: General aviation aircraft are often used by law enforcement to assist officers on the ground with suspect apprehension as they can provide an aerial view. Transporting suspects to jail is usually done by ground vehicles. Escorting passenger airliners in an emergency is not a typical use, and aerial spraying during a fire is usually done by specialized firefighting aircraft.
For Question 17: Engineering practices can be used many times, used only once, or not used at all depending on the project requirements.
