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.

Q: John's lack of religious conviction has been noted by contemporary chroniclers and later historians, with some suspecting that John was at best impious, or even atheistic, a very serious issue at the time. Contemporary chroniclers catalogued his various anti-religious habits at length, including his failure to take communion, his blasphemous remarks, and his witty but scandalous jokes about church doctrine, including jokes about the implausibility of the Resurrection. They commented on the paucity of John's charitable donations to the church. Historian Frank McLynn argues that John's early years at Fontevrault, combined with his relatively advanced education, may have turned him against the church. Other historians have been more cautious in interpreting this material, noting that chroniclers also reported John's personal interest in the life of St Wulfstan of Worcester and his friendships with several senior clerics, most especially with Hugh of Lincoln, who was later declared a saint. Financial records show a normal royal household engaged in the usual feasts and pious observances – albeit with many records showing John's offerings to the poor to atone for routinely breaking church rules and guidance. The historian Lewis Warren has argued that the chronicler accounts were subject to considerable bias and the King was "at least conventionally devout," citing his pilgrimages and interest in religious scripture and commentaries.

A: Historians suspected that John was at best what?

Q: From 7 September 1940, one year into the war, London was bombed by the Luftwaffe for 57 consecutive nights. More than one million London houses were destroyed or damaged and more than 40,000 civilians were killed, almost half of them in London. Ports and industrial centres outside London were also attacked. The main Atlantic sea port of Liverpool was bombed, causing nearly 4,000 deaths within the Merseyside area during the war. The North Sea port of Hull, a convenient and easily found target or secondary target for bombers unable to locate their primary targets, was subjected to 86 raids in the Hull Blitz during the war, with a conservative estimate of 1,200 civilians killed and 95 percent of its housing stock destroyed or damaged. Other ports including Bristol, Cardiff, Portsmouth, Plymouth, Southampton and Swansea were also bombed, as were the industrial cities of Birmingham, Belfast, Coventry, Glasgow, Manchester and Sheffield. Birmingham and Coventry were chosen because of the Spitfire and tank factories in Birmingham and the many munitions factories in Coventry. The city centre of Coventry was almost destroyed, as was Coventry Cathedral.

A: How many nights did the Luftwaffe bomb London?

Q: The reinforcement type defines two major classes of materials - woven and non-woven. Woven reinforcements are cheaper, but the high dielectric constant of glass may not be favorable for many higher-frequency applications. The spatially nonhomogeneous structure also introduces local variations in electrical parameters, due to different resin/glass ratio at different areas of the weave pattern. Nonwoven reinforcements, or materials with low or no reinforcement, are more expensive but more suitable for some RF/analog applications.

A:
Along with the non-woven class, what makes up the reinforcement type materials?
