TASK DEFINITION: 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.
PROBLEM: 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.

SOLUTION: In 2013, ABC's identity was revamped by what design agency?

PROBLEM: In cpDNA, there are several A → G deamination gradients. DNA becomes susceptible to deamination events when it is single stranded. When replication forks form, the strand not being copied is single stranded, and thus at risk for A → G deamination. Therefore, gradients in deamination indicate that replication forks were most likely present and the direction that they initially opened (the highest gradient is most likely nearest the start site because it was single stranded for the longest amount of time). This mechanism is still the leading theory today; however, a second theory suggests that most cpDNA is actually linear and replicates through homologous recombination. It further contends that only a minority of the genetic material is kept in circular chromosomes while the rest is in branched, linear, or other complex structures.

SOLUTION: What kind of gradients does cpDNA have?

PROBLEM: Because of their long life, fast switching times, and their ability to be seen in broad daylight due to their high output and focus, LEDs have been used in brake lights for cars' high-mounted brake lights, trucks, and buses, and in turn signals for some time, but many vehicles now use LEDs for their rear light clusters. The use in brakes improves safety, due to a great reduction in the time needed to light fully, or faster rise time, up to 0.5 second faster[citation needed] than an incandescent bulb. This gives drivers behind more time to react. In a dual intensity circuit (rear markers and brakes) if the LEDs are not pulsed at a fast enough frequency, they can create a phantom array, where ghost images of the LED will appear if the eyes quickly scan across the array. White LED headlamps are starting to be used. Using LEDs has styling advantages because LEDs can form much thinner lights than incandescent lamps with parabolic reflectors.

SOLUTION:
Because of their high output, LED lights are very useful where?
