Answer :
To determine the usefulness of the tables for the purpose of discussing shared bills among three roommates, we should carefully evaluate the clarity and completeness of each table.
The options given are:
1. C, A, D, B
2. A, C, B, D
3. B, A, D, C
4. B, C, D, A
Now, let's break down why each table can be placed in a particular order from least helpful to most helpful:
### Table C:
This table is the least helpful because:
- The content is split into multiple cells, making it less organized and unclear.
- It doesn't effectively differentiate between shared and individual bills.
- Overall, it lacks the clarity needed for discussing shared expenses.
### Table A:
This table is somewhat helpful but not the best because:
- It lists a mix of shared and individual items without clear categorization or separation.
- However, it does list more items, which is a slight improvement over Table C.
### Table D:
This table is fairly helpful with partial clarity because:
- It has a partial structure that can support the clarity of shared bills.
- However, the categorization could still be improved.
### Table B:
This is the most helpful table because:
- It clearly distinguishes between shared bills and individual bills.
- The organization and presentation make it easier to understand and discuss the shared expenses.
Considering these evaluations, the tables should be ranked in the following order from least helpful to most helpful:
[tex]\[ \text{C, A, D, B} \][/tex]
Hence, the correct order based on the given available options is:
1. C, A, D, B
Therefore, the answer is:
[tex]\[ \boxed{C, A, D, B} \][/tex]
