why might a country choose to devalue its currency?\no to please its trading partners\no to encourage…

Brief Explanations:

Devaluing a currency makes a country's goods cheaper for foreign - buyers in foreign currency terms. This increases the competitiveness of domestic products in international markets, thus encouraging exports. It does not please trading partners as it can lead to trade imbalances for them. It discourages imports as foreign goods become more expensive in the devaluing country's currency. And it has no direct relation to reducing taxes.

Answer:

to encourage exports
