To increase the value of their currency, Songland's Central Bank should _____ Euros in the Foreign Exchange Market to raise interest rates and increase demand for the Songland dollar.

To increase the value of their currency, Songland's Central Bank should buy Euros in the Foreign Exchange Market. When the bank buys Euros, it uses its own currency, the Songland dollar, to make the purchase. This action reduces the supply of Songland dollars in the market, which can lead to higher interest rates as there is less money available for lending. As interest rates rise, more investors will want to hold Songland dollars because they can earn more from savings or investments in that currency. For example, if the Central Bank buys a large amount of Euros, it can make the Songland dollar more attractive, leading to an increase in its value.
