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 Q]: In 1584, Elizabeth I granted a charter to Sir Walter Raleigh, for whom the state capital is named, for land in present-day North Carolina (then part of the territory of Virginia). It was the second American territory which the English attempted to colonize. Raleigh established two colonies on the coast in the late 1580s, but both failed. The fate of the "Lost Colony" of Roanoke Island remains one of the most widely debated mysteries of American history. Virginia Dare, the first English child to be born in North America, was born on Roanoke Island on August 18, 1587; Dare County is named for her.
[EX A]: Who is the North Carolina state capital named for?

[EX Q]: In 1982, the US Mint began minting pennies coated in copper but made primarily of zinc. With the new zinc pennies, there is the potential for zinc toxicosis, which can be fatal. One reported case of chronic ingestion of 425 pennies (over 1 kg of zinc) resulted in death due to gastrointestinal bacterial and fungal sepsis, whereas another patient, who ingested 12 grams of zinc, only showed lethargy and ataxia (gross lack of coordination of muscle movements). Several other cases have been reported of humans suffering zinc intoxication by the ingestion of zinc coins.
[EX A]: What coin, as of 1982, is now primarily made of zinc?

[EX Q]: Electrochemical migration (ECM) is the growth of conductive metal filaments on or in a printed circuit board (PCB) under the influence of a DC voltage bias. Silver, zinc, and aluminum are known to grow whiskers under the influence of an electric field. Silver also grows conducting surface paths in the presence of halide and other ions, making it a poor choice for electronics use. Tin will grow "whiskers" due to tension in the plated surface. Tin-Lead or solder plating also grows whiskers, only reduced by the percentage Tin replaced. Reflow to melt solder or tin plate to relieve surface stress lowers whisker incidence. Another coating issue is tin pest, the transformation of tin to a powdery allotrope at low temperature.
[EX A]:
What's the process whereby metal filaments are grown on or in a PCB via DC voltage?
