Using Representation Systems Flexibly - Example 6

The solution is (A). Statement I is correct, for the sentence “Research has shown that eating cocoa-containing chocolate may contribute slightly towards reducing blood pressure.” points to a positive relationship between eating cocoa-containing chocolate and reducing blood pressure. Eating cocoa-containing chocolate brings about a reduction in blood pressure, therefore must point towards reduction in blood pressure.
Statement II is incorrect. The sentence “Cocoa-containing chocolate also contains a substance which supports the healing of wounds and reduces the risk of stomach diseases.” points to a positive relationship between eating cocoa-containing chocolate and the healing of wounds and a negative relationship between eating cocoa-containing chocolate and a risk of stomach diseases. However, the arrows should point towards supporting the healing of wounds and towards the risk of stomach diseases and not towards eating cocoa-containing chocolate.
