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. Avoid creating questions that (i) can be answered correctly without actually understanding the paragraph and (ii) uses same words or phrases given in the passage.

Ex Input:
The predominant religions in Zhejiang are Chinese folk religions, Taoist traditions and Chinese Buddhism. According to surveys conducted in 2007 and 2009, 23.02% of the population believes and is involved in cults of ancestors, while 2.62% of the population identifies as Christian, decreasing from 3.92% in 2004. The reports didn't give figures for other types of religion; 74.36% of the population may be either irreligious or involved in worship of nature deities, Buddhism, Confucianism, Taoism, folk religious sects, and small minorities of Muslims.

Ex Output:
What is another predominant religion of Zhejiang besides Chinese folk religions and Taoist traditions?


Ex Input:
In December 1993, the Famicom received a similar redesign. It also loads cartridges through a covered slot on the top of the unit and uses non-hardwired controllers. Because HVC-101 used composite video output instead of being RF only like the HVC-001, Nintendo marketed the newer model as the AV Famicom (AV仕様ファミコン, Eibui Shiyō Famikon?). Since the new controllers don't have microphones on them like the second controller on the original console, certain games such as the Disk System version of The Legend of Zelda and Raid on Bungeling Bay will have certain tricks that cannot be replicated when played on an HVC-101 Famicom without a modded controller. However, the HVC-101 Famicom is compatible with most NES controllers due to having the same controller port. Nintendo had also released a 3D graphic capable headset. However, this peripheral was never released outside Japan.[citation needed]

Ex Output:
What month and year did the Famicom receive a redesign?


Ex Input:
A servomotor is a motor, very often sold as a complete module, which is used within a position-control or speed-control feedback control system mainly control valves, such as motor-operated control valves. Servomotors are used in applications such as machine tools, pen plotters, and other process systems. Motors intended for use in a servomechanism must have well-documented characteristics for speed, torque, and power. The speed vs. torque curve is quite important and is high ratio for a servo motor. Dynamic response characteristics such as winding inductance and rotor inertia are also important; these factors limit the overall performance of the servomechanism loop. Large, powerful, but slow-responding servo loops may use conventional AC or DC motors and drive systems with position or speed feedback on the motor. As dynamic response requirements increase, more specialized motor designs such as coreless motors are used. AC motors' superior power density and acceleration characteristics compared to that of DC motors tends to favor PM synchronous, BLDC, induction, and SRM drive applications.

Ex Output:

What may servo motors be used for?
