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:
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.

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


Ex Input:
In September 2003, a new type of blue LED was demonstrated by Cree that consumes 24 mW at 20 milliamperes (mA). This produced a commercially packaged white light giving 65 lm/W at 20 mA, becoming the brightest white LED commercially available at the time, and more than four times as efficient as standard incandescents. In 2006, they demonstrated a prototype with a record white LED luminous efficacy of 131 lm/W at 20 mA. Nichia Corporation has developed a white LED with luminous efficacy of 150 lm/W at a forward current of 20 mA. Cree's XLamp XM-L LEDs, commercially available in 2011, produce 100 lm/W at their full power of 10 W, and up to 160 lm/W at around 2 W input power. In 2012, Cree announced a white LED giving 254 lm/W, and 303 lm/W in March 2014. Practical general lighting needs high-power LEDs, of one watt or more. Typical operating currents for such devices begin at 350 mA.

Ex Output:
In what year was a new type of blue LED produced?

The oldest attestation of human presence in Galicia has been found in the Eirós Cave, in the municipality of Triacastela, which has preserved animal remains and Neanderthal stone objects from the Middle Paleolithic. The earliest culture to have left significant architectural traces is the Megalithic culture which expanded along the western European coasts during the Neolithic and Calcolithic eras. Thousands of Megalithic tumuli are distributed throughout the country, but mostly along the coastal areas. Within each tumulus is a stone burial chamber known locally as anta (dolmen), frequently preceded by a corridor. Galicia was later fully affected by the Bell Beaker culture. While its rich mineral deposits - tin and gold - led to the development of Bronze Age metallurgy, and to the commerce of bronze and gold items all along the Atlantic façade of Western Europe, where a common elite's culture evolved during the Atlantic Bronze Age.

Ex Output:
Where in Galicia has the oldest evidence of humans been found?
