Question 9.

Let us pay heed to the following excerpt: "...In actuality, our own currency system today has some similarities even as it is changing in front of our eyes. . . . We have cash - coins for small transactions like paying for parking at a meter, and banknotes for other items; cheques and debit/credit cards for other, often larger, types of payments. At the same time, we are shifting to electronic banking and making payments online. Some young people never use cash [and] do not know how to write a cheque..." 

Based on the above, we can infer Options A, B and C as the similarities that are implied. Concerning Option D, while the author does mention the present currency system as a changing/dynamic one, the same cannot be said about the Tang dynasty. The author does not highlight this element as a similarity.  Hence, Option D is the correct answer.
