Option A: The writer makes no such assertions….Grain, because it rotted easily, was not used nearly as much as coins and textiles,….The minimal use of grains in comparison to coinage and textiles is shown. It is therefore incomprehensible that government business did not make use of perishable currencies like wheat.
Option B: The author merely says, ……Coins did have certain advantages: they were durable, recognisable and provided a convenient medium of exchange, especially for smaller transactions…."It would be incorrect to present them as more valuable than textile currency."
Option C: The author states in the last paragraph that this statement is understandable,…..In actuality, our own currency system today has some similarities even as it is changing in front of our eyes….. hence Option C is a legitimate inference.
Option D: Given how the author presents the following,…Grain, because it rotted easily, was not used nearly as much as coins and textiles, but taxpayers were required to pay grain to the government as a share of their annual tax obligations, and official salaries were expressed in weights of grain. . . . this would be imprecise. This statement differs from how it is portrayed.
The question asks us to identify which aspect related to textiles as currency during the Tang period is NOT indicated by the words "steady" and "stable" used by the author. We need to analyze these terms within the context of the passage.
The passage indicates that the dimensions of a bolt of silk were consistent ("steady") over a long period, implying "reliable measurements." Additionally, it mentions that textile production was widespread, with fewer issues concerning supply, implying "reliable supply." It also states that the values of textiles were more stable than coins, suggesting "reliable quality."
However, there is no indication in the passage that discusses transportation in terms of the words "steady" and "stable." The sentence relevant to transportation describes the weight advantage of textiles over coins for large transactions but does not relate to the reliability or stability of transportation itself.
Therefore, the answer is: reliable transportation.
Read the sentence and infer the writer's tone: "The politician's speech was filled with lofty promises and little substance, a performance repeated every election season."
