- Blank (i): The phrase "poor planning and disorganization" suggests that they were not tackling the problem effectively or immediately.
- A. expedited: means to speed up, which contradicts "poor planning and disorganization."
- B. postponed: means to delay, which fits the idea of not attacking the root of the problem.
- C. accelerated: means to speed up, similar to expedited.

So, (i) postponed is the best fit.
- Blank (ii): "They were obliged to... a... last-minute solution." This implies they had to put a solution into action.
- D. implement: means to put into effect, which fits perfectly.
- E. envision: means to imagine, which doesn't fit the context of being "obliged" to act.
- F. reject: means to refuse, which contradicts finding a solution.

So, (ii) implement is the best fit.

- Blank (iii): Given the "poor planning and disorganization" and being forced into a "lastminute solution," the solution itself would likely be born out of necessity, not careful thought.
- G. measured: implies careful consideration and planning, which contradicts the scenario.
- H. premeditated: implies thought out beforehand, also contradictory to a "last-minute" solution due to disorganization.
- I. desperate: implies a strong need or urgency, fitting the situation where they had "no other recourse left."

So, (iii) desperate is the best fit.

Therefore, the completed sentence is: As a result of poor planning and disorganization, the young team (i) postponed attacking the root of the problem. This went on until there was no other recourse left to them. They were obliged to (ii) implement a (iii) desperate last-minute solution to the problem.

The correct options are:
- Blank (i): B. postponed
- Blank (ii): D. implement
- Blank (iii): I. desperate
