To achieve the goals of Project Apollo, the following options are applicable:
A. Scientific data had to be collected and analyzed.
B. Engineers had to brainstorm solutions to complex problems.
D. Many pieces of equipment had to be designed, prototyped, and tested.
Option C ("Engineers had to ignore concerns about astronaut safety in order to meet time constraints") is not a necessary or acceptable aspect of achieving the goals of Project Apollo, as astronaut safety was a critical priority throughout the program.
