In the given question, a passage with seven blanks labeled (A) – (G) is given. You are required to fill the correct word in the blanks.

It’s not easy to accurately ___(A)___ what humans want and when they will want it. We’re demanding creatures, expecting the world to deliver speedy ___(B)___ to our increasingly complex and diverse modern-day problems. Over the last few decades, researchers have developed a range of ___(C)___ mathematical solutions that can allocate resources across a variety of industries and scenarios so they can attempt to keep up with the daily demands our lives place on them. But when an allocation made at one time ___(D)___ subsequent allocations, the problem becomes dynamic, and the passing of time must be considered as part of the equation. This throws a mathematical spanner in the works, requiring these solutions to now take into account the changing and ___(E)___ nature of the real world.

Such problems are collectively known as dynamic resource allocation problems. They ___(F)___ up anywhere you find a limited resource that needs to be assigned in real time. Whether you’re waiting for a taxi or a next-day delivery, the list of dynamic resource allocation problems and their everyday applications is “almost endless” according to Warren Powell, an engineer at Princeton University who has been ___(G)___ these problems since the 1980s.
