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: However a log-periodic dipole array consists of a number of dipole elements of different lengths in order to obtain a somewhat directional antenna having an extremely wide bandwidth: these are frequently used for television reception in fringe areas. The dipole antennas composing it are all considered "active elements" since they are all electrically connected together (and to the transmission line). On the other hand, a superficially similar dipole array, the Yagi-Uda Antenna (or simply "Yagi"), has only one dipole element with an electrical connection; the other so-called parasitic elements interact with the electromagnetic field in order to realize a fairly directional antenna but one which is limited to a rather narrow bandwidth. The Yagi antenna has similar looking parasitic dipole elements but which act differently due to their somewhat different lengths. There may be a number of so-called "directors" in front of the active element in the direction of propagation, and usually a single (but possibly more) "reflector" on the opposite side of the active element.
Example Output: What type of antenna formation is made up of multiple dipole elements of varying lengths?

Example Input: Wu Chinese has a three-way distinction in stops and affricates: /p pʰ b/. In addition to aspirated and unaspirated consonants, there is a series of muddy consonants, like /b/. These are pronounced with slack or breathy voice: that is, they are weakly voiced. Muddy consonants as initial cause a syllable to be pronounced with low pitch or light (陽 yáng) tone.
Example Output: What has a three-way distinction in regards to stops and affricates?

Example Input: In 1965, Pope Paul VI decreed in his motu proprio Ad Purpuratorum Patrum that patriarchs of the Eastern Catholic Churches who were named cardinals (i.e., patriarch cardinals) would also be part of the episcopal order, ranking after the six cardinal bishops of the suburbicarian sees (who had been relieved of direct responsibilities for those sees by Pope John XXIII three years earlier). Patriarch cardinals do not receive title of a suburbicarian see, and as such they cannot elect the dean or become dean. There are currently three Eastern Patriarchs who are cardinal bishops:
Example Output:
Patriarch cardinals are not given what title?
