C. Is a Factual Statement
This one is tricky, because scientific law can explain an observation, or be used to make a prediction, but I believe that C. is the most correct of the 4 answers.
Correct answer:
The exchange rate between the U.S. dollar and the euro changes from 1:95 to 1:92.
In the first statement despite having a change from 1:95 to 1: 102 between the US dollar, does not describe a strong US dollar because the relationship is not growth. On the other hand, the change from 1:95 to 1:92 is a growth ratio between the change from dollar to euro. Staying at 1:95 does not mean either growth or a strong US dollar.
The Maritime Silk Road was the name given by a Japanese scholar in 1967 to distinguish it from the traditional Silk Road. This route surrounded many oceans and seas including; South China Sea, Strait of Malacca, Indian Ocean, Gulf of Bengal, Arabian Sea, Persian Gulf and the Red Sea.
