September exam Q1 (a) continued

Following on from my last question and again, thanks so much for your advice, I am wondering if there are any specific financial issues that can be discussed at all?
NPV can’t because there’s no discount rate, currency fluctuations can’t because it’s the same currency, you could say what the payback period is but it’s not very helpful because no info is given on what would be an acceptable payback period or not. So apart from a comment that the amounts in future years may be affected by changes in inflation and interest rates, what could there be?
