2.1 Opposing claims
Returning to the benefits of carrot for our eyesight, here is an example of an opposing claim: ‘Beta carotene supplements will not strengthen eyesight or slow decline in healthy people.’
You can add this to your argument map by adding two further items. Apart from the item above, you need to also state explicitly that ‘Carrots are a source of beta carotene’. In this case, the two claims are connected to the main claim by an OPPOSE, rather than a SUPPORT box, in Figure 3.
