Answer: Depreciate
Step-by-step explanation:
The Economist is a widely respected financial and economic magazine which means that their articles can cause movements in the market especially when backed up by analysts.
The Economist believes that the Tunisian Dinar will rise relative to the Peruvian Sol, this means that the Peruvian Sol will depreciate against the Tunisian Diner. Some people and entities holding Peruvian Sol assets will try to offload it so that they do not suffer losses.
This increase in supply and reduction in demand for the Peruvian Sol will lead to it depreciating.
