Input: Article: Unlike most languages that use alphabets to indicate the pronunciation, Chinese characters have developed from logograms that do not always give hints to its pronunciation. Although the written characters remained relatively consistent for the last two thousand years, the pronunciation and grammar in different regions has developed to an extent that the varieties of the spoken language are often mutually unintelligible. As a series of migration to the south throughout the history, the regional languages of the south, including Xiang, Wu, Gan, Min, Yue (Cantonese), and Hakka often show traces of Old Chinese or Middle Chinese. From the Ming dynasty onward, Beijing has been the capital of China and the dialect spoken in Beijing has had the most prestige among other varieties. With the founding of the Republic of China, Standard Mandarin was designated as the official language, based on the spoken language of Beijing. Since then, other spoken varieties are regarded as fangyan (dialects). Cantonese is still the most commonly used language in Hong Kong, Macau and among some overseas Chinese communities, whereas Southern Min has been accepted in Taiwan as an important local language along with Mandarin.

Now answer this question: From the time of the Ming dynasty, what city was the capital of China?

Output: Beijing

Input: Article: There are both practical and theoretical difficulties in determining h. The practical difficulties can be illustrated by the fact that the two most accurate methods, the watt balance and the X-ray crystal density method, do not appear to agree with one another. The most likely reason is that the measurement uncertainty for one (or both) of the methods has been estimated too low it is (or they are) not as precise as is currently believed but for the time being there is no indication which method is at fault.

Now answer this question: Which method is at fault or the discrepancy?

Output:
there is no indication which method is at fault
