Answer:
The correct answer is: tactical; problem-solving.
Step-by-step explanation:
A tactical team is a group of highly-specialized individuals that come together in order to carry out risky operations following a step-by-step plan. Problem-solving teams are groups where individuals come together in order to fix or correct an error. They do not have a set plan of action since while fixing a problem they are likely to find out more fields of exploration.
In that case, the cardiac surgery team is a tactical team while the Sandia nuclear weapons laboratory team is a problem-solving team.
