Let's examine each listed statement about MCDA to determine its alignment with typical MCDA process concepts.
Option 1: 'Answers A, B, C, D, E and G are correct.' This claims that A, B, C, D, E, and G are all true while F is false. We should assess A and G in combination with the others. A states that 'Values not numbers should be the driving force behind our decision making.' In many MCDA approaches, numbers (weights, scores) play a central role in the formal evaluation, even though stakeholder values influence the choice and interpretation. Claiming that only non-numeric values should drive decision making oversimplifies and generally conflicts with the quantitative nature of MCDA. Therefore A is questionable or incorrect in standard MCDA practice. G says 'The results should be graphed to help explain the pattern of results.' Visualization is common and helpful in MCDA, so G is typically true. B says 'MCDA helps us identify options and then systematically evaluate them based upon a set of decision criteria.' This is a core description of MCDA: enumerate options, define criteria, and evaluate. C says 'First step is to Identify options.' In many MCDA frameworks, listing alternatives is indeed an early step. D says 'Decision criteria and sub-criteria are identified as the second step.' Some frameworks place criteria definition after listing options, sometimes with sub-criteria defined subsequently; describing criteria as the second step is believable in many curricula. E says 'Weighted criteria must add up to 1.' In weighted MCDA, weights are normalized to sum to 1 (or 100%), so this is a standard requirement. F says 'Stakeholders' values do not interfere with the process.' This is typically false: stakeholders’ values influence criteria selection, weighting, and interpretation; they do interfere. Since A is questionable and F is false, Option 1, which includes A as correct and F as excluded, is inconsistent with standard MCDA understanding.
Option 2: 'All answers are correct.' Given that A is not typically correct and F is not correct, this option is unlikely to be true in standard MCDA interpretation. Therefore this option is not a good fit.
Option 3: 'Answers B, C, D, E, F and G are correct.' This asserts F is correct (stakeholders’ values do not interfere), which contradicts the common role of stakeholder values in MCDA, making this option incorrect.
Option 4: 'Answers A, B, E, F and G are correct.' This asserts A is correct (values, not numbers, driving decision making) and F is correct (stakeholders’ values do not interfere). Both A and F conflict with standard MCDA practice as described above, so this option is also inconsistent.
In summary, the statements B, C, D, E, and G align with standard MCDA methodology and practices (identifying options, early emphasis on criteria, normalization of weights to sum to 1, and the usefulness of graphs), while A and F contradict typical MCDA principles (the central role of numbers/weights and the influence of stakeholder values). Consequently, the options that claim all of A–G or include F as correct are incorrect, and the option that excludes F but includes A is also inconsistent with MCDA norms. The correct interpretation would be that the true statements are B, C, D, E, and G, while A and F are not correct in the usual MCDA framework. However, since the question structure presents combined options rather than listing the individual true statements, none of the provided composite options perfectly matches the standard set of true statements. The key takeaway is: B, C, D, E, and G reflect typical MCDA features, while A and F do not.
