When the U. S. dollar appreciates against other currencies, U. S. goods can be to consumers in foreign countries but can have implications for American companies with branch operations overseas.

The correct answer is letter "B": more expensive; negative.

Explanation:

A currency appreciates when its value increases in front of the value of other currencies. It is beneficial for countries where the appreciated currency represents the official method of payment but for foreign countries, it is translated as a devaluation of their currency.

Thus, if the U.S. dollar appreciates, U.S. goods will be more expensive everywhere where the U.S. dollar is not the official currency. However, for firms operating in both the U.S. and abroad, this scenario will be negative because when they bring their money back to the U.S. they will have to change the foreign currency to U.S. dollars at a higher exchange rate, meaning entities will have lower U.S. dollars.

the correct answer option is b. a single paragraph.

explanation:

when you are thinking about paragraph​ topics, you should always choose a subject that can be adequately addressed in a single paragraph.

a paragraph is a piece of writing consisting of a few sentences that deal with a single theme. it has only a single idea that the paragraph revolves around and talks about.

so a paragraph topic must be chosen wisely where a single idea can be communicated in a single paragraph.
