This task is about reading the given passage and construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) its answer is a continuous text span from the paragraph.

Example Input: Firstly conceived and still used today for optical storage devices (CD-RW drives, DVD drives, etc.), several manufacturers offer external portable USB hard disk drives, or empty enclosures for disk drives. These offer performance comparable to internal drives, limited by the current number and types of attached USB devices, and by the upper limit of the USB interface (in practice about 30 MB/s for USB 2.0 and potentially 400 MB/s or more for USB 3.0). These external drives typically include a "translating device" that bridges between a drive's interface to a USB interface port. Functionally, the drive appears to the user much like an internal drive. Other competing standards for external drive connectivity include eSATA, ExpressCard, FireWire (IEEE 1394), and most recently Thunderbolt.
Example Output: Several manufacturers offer what?

Example Input: Historically, the name Armenian has come to internationally designate this group of people. It was first used by neighbouring countries of ancient Armenia. The earliest attestations of the exonym Armenia date around the 6th century BC. In his trilingual Behistun Inscription dated to 517 BC, Darius I the Great of Persia refers to Urashtu (in Babylonian) as Armina (in Old Persian; Armina ( ) and Harminuya (in Elamite). In Greek, "Armenians" is attested from about the same time, perhaps the earliest reference being a fragment attributed to Hecataeus of Miletus (476 BC). Xenophon, a Greek general serving in some of the Persian expeditions, describes many aspects of Armenian village life and hospitality in around 401 BC. He relates that the people spoke a language that to his ear sounded like the language of the Persians.
Example Output: How long ago has the term 'Armenia' been used?

Example Input: In China, which uses simplified Chinese characters, the Xiandai Hanyu Changyong Zibiao (, Chart of Common Characters of Modern Chinese) lists 2,500 common characters and 1,000 less-than-common characters, while the Xiandai Hanyu Tongyong Zibiao (, Chart of Generally Utilized Characters of Modern Chinese) lists 7,000 characters, including the 3,500 characters already listed above. GB2312, an early version of the national encoding standard used in the People's Republic of China, has 6,763 code points. GB18030, the modern, mandatory standard, has a much higher number. The New Hanyu Shuiping Kaoshi (, Chinese Proficiency Test) covers approximately 2,600 characters at its highest level (level six).
Example Output:
What country uses simplified Chinese characters?
