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.

A revised version of the ABC logo was introduced for promotions for the 2013–14 season during the network's upfront presentation on May 14, 2013, and officially introduced on-air on June 17 (although some affiliates implemented the new design prior to then), as part of an overhaul of ABC's identity by design agency LoyalKaspar. The updated logo carries a simpler gloss design than the previous version, and contains lettering more closely resembling Paul Rand's original version of the circle logo. The logo is displayed on-air, online and in print advertising in four variants shading the respective color used with the circle design's native black coloring: a gold version is primarily used on entertainment-oriented outlets (such as ABC.com, WATCH ABC, and by ABC Studios) and the on-screen bug; steel blue and dark grey versions are used primarily by ABC News; a red version is used for ESPN on ABC, while all four variants are used selectively in advertising and by affiliates. A new custom typeface, "ABC Modern" (which was inspired by the logotype), was also created for use in advertising and other promotional materials.
In 2013, ABC's identity was revamped by what design agency?

Diagnosis of infectious disease is nearly always initiated by medical history and physical examination. More detailed identification techniques involve the culture of infectious agents isolated from a patient. Culture allows identification of infectious organisms by examining their microscopic features, by detecting the presence of substances produced by pathogens, and by directly identifying an organism by its genotype. Other techniques (such as X-rays, CAT scans, PET scans or NMR) are used to produce images of internal abnormalities resulting from the growth of an infectious agent. The images are useful in detection of, for example, a bone abscess or a spongiform encephalopathy produced by a prion.
How is diagnosis of infectious disease almost always initiated?

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.
What may servo motors be used for?
