Problem: Please answer a question about the following article about Han dynasty:
One of the Han's greatest mathematical advancements was the world's first use of negative numbers. Negative numbers first appeared in the Nine Chapters on the Mathematical Art as black counting rods, where positive numbers were represented by red counting rods. Negative numbers are used in the Bakhshali manuscript of ancient India, but its exact date of compilation is unknown. Negative numbers were also used by the Greek mathematician Diophantus in about 275 AD, but were not widely accepted in Europe until the 16th century AD.
What Indian manuscript also contains the useage of negative numbers?
A: Bakhshali

Problem: Please answer a question about the following article about MP3:
Decoding, on the other hand, is carefully defined in the standard. Most decoders are "bitstream compliant", which means that the decompressed output that they produce from a given MP3 file will be the same, within a specified degree of rounding tolerance, as the output specified mathematically in the ISO/IEC high standard document (ISO/IEC 11172-3). Therefore, comparison of decoders is usually based on how computationally efficient they are (i.e., how much memory or CPU time they use in the decoding process).
Decoders are usually compared by examining which factor?
A: computationally efficient
Problem: Please answer a question about the following article about Bermuda:
This is a socio-economic bloc of nations in or near the Caribbean Sea. Other outlying member states include the Co-operative Republic of Guyana and the Republic of Suriname in South America, along with Belize in Central America. The Turks and Caicos Islands, an associate member of CARICOM, and the Commonwealth of The Bahamas, a full member of CARICOM, are in the Atlantic, but near to the Caribbean. Other nearby nations or territories, such as the United States, are not members (although the US Commonwealth of Puerto Rico has observer status, and the United States Virgin Islands announced in 2007 they would seek ties with CARICOM). Bermuda, at roughly a thousand miles from the Caribbean Sea, has little trade with, and little economically in common with, the region, and joined primarily to strengthen cultural links.
Why did Bermuda join CARICOM?
A:
primarily to strengthen cultural links.
