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.

Example Input: Three daily newspapers serve Melbourne: the Herald Sun (tabloid), The Age (formerly broadsheet, now compact) and The Australian (national broadsheet). Six free-to-air television stations service Greater Melbourne and Geelong: ABC Victoria, (ABV), SBS Victoria (SBS), Seven Melbourne (HSV), Nine Melbourne (GTV), Ten Melbourne (ATV), C31 Melbourne (MGV) community television. Each station (excluding C31) broadcasts a primary channel and several multichannels. C31 is only broadcast from the transmitters at Mount Dandenong and South Yarra. Hybrid digital/print media companies such as Broadsheet and ThreeThousand are based in and primarily serve Melbourne.
Example Output: How many daily newspapers serve Melbourne?

Example Input: 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.
Example Output: What coin, as of 1982, is now primarily made of zinc?

Example Input: These processes are also important in biological responses to pollution; for example, sulfate-reducing bacteria are largely responsible for the production of the highly toxic forms of mercury (methyl- and dimethylmercury) in the environment. Non-respiratory anaerobes use fermentation to generate energy and reducing power, secreting metabolic by-products (such as ethanol in brewing) as waste. Facultative anaerobes can switch between fermentation and different terminal electron acceptors depending on the environmental conditions in which they find themselves.
Example Output:
What is sulfate-reducing bacteria accountable for?
