The correct answer is C. PRQS.
The first sentence, S1, states that payment for imports and exports is made through a system called foreign exchange. The second sentence, P, states that the value of the money of one country in relation to the money of other countries is agreed upon. This is the definition of a foreign exchange rate. The third sentence, Q, states that these rates of exchange vary from time to time. This is because the value of currencies is constantly changing based on a variety of factors, such as supply and demand, economic conditions, and political stability. The fourth sentence, R, gives an example of how foreign exchange rates can vary. It states that an American dollar or a British pound sterling is worth certain amounts in the money of other countries. For instance, a United States dollar is sometimes worth 12 pesos in Mexico, but another time it may be worth eight pesos. The fifth sentence, S, is not necessary to the main point of the paragraph, which is to explain the concept of foreign exchange rates. The sixth sentence, S6, is also not necessary to the main point of the paragraph. It simply repeats the information that was already given in the fourth sentence. Therefore, the correct sequence of sentences is C. PRQS.
