A Select all the criteria engineers needed to consider while solving the carbon dioxide problem.

The solution must filter out enough carbon dioxide from the air to keep three astronauts alive during the trip back to Earth.
The astronauts might not survive the trip back to Earth because the carbon dioxide filters in the lunar module and the command module were different shapes.
A physical prototype of the solution must be built and tested, and the instructions to build it must be communicated to the astronauts.
Only the materials available to the astronauts on the spacecraft could be used in the solution.

When addressing the carbon dioxide problem for the astronauts, engineers needed to consider the following criteria:

  1. Adequate Filtration Capacity: The solution must filter out enough carbon dioxide from the air to keep three astronauts alive during the trip back to Earth.

  2. Compatibility with Existing Systems: The astronauts might not survive the trip back to Earth because the carbon dioxide filters in the lunar module and the command module were different shapes. Therefore, a solution must be compatible with the existing equipment.

  3. Physical Prototype Testing: A physical prototype of the solution must be built and tested to ensure it works effectively under actual conditions.

  4. Communication of Instructions: Clear and accurate instructions for building the prototype must be communicated to the astronauts, as they need to understand how to construct the solution with the materials and resources available.

  5. Material Availability: Only materials available to the astronauts on the spacecraft could be used in the solution, ensuring that the engineers work within the constraints of the environment.

These criteria ensure that the engineers develop a feasible, effective, and safe solution for managing carbon dioxide levels during the return trip to Earth.
