Free sample exam error (spoiler alert)

anyone that has taken the free sample exam may have noticed this: question 24 asks for the operation effect of currency movement, and it says to calculate the operational effect by multiplying the change in the income statement (in local currency) by the previous periods average exchange rate… but then it shows the example of operating income x 2007 average exchange rate shouldnt it be 2006?

According to the formula for sure.
