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: In the Hellenistic period, there was much continuity in Greek religion: the Greek gods continued to be worshiped, and the same rites were practiced as before. However the socio-political changes brought on by the conquest of the Persian empire and Greek emigration abroad meant that change also came to religious practices. This varied greatly on location, Athens, Sparta and most cities in the Greek mainland did not see much religious change or new gods (with the exception of the Egyptian Isis in Athens), while the multi-ethnic Alexandria had a very varied group of gods and religious practices, including Egyptian, Jewish and Greek. Greek emigres brought their Greek religion everywhere they went, even as far as India and Afghanistan. Non-Greeks also had more freedom to travel and trade throughout the Mediterranean and in this period we can see Egyptian gods such as Serapis, and the Syrian gods Atargatis and Hadad, as well as a Jewish synagogue, all coexisting on the island of Delos alongside classical Greek deities. A common practice was to identify Greek gods with native gods that had similar characteristics and this created new fusions like Zeus-Ammon, Aphrodite Hagne (a Hellenized Atargatis) and Isis-Demeter. Greek emigres faced individual religious choices they had not faced on their home cities, where the gods they worshiped were dictated by tradition.
Example Output: What Egyptian god was worshipped in Athens?

Example Input: Studies by Nathaniel Kleitman in 1938 and by Derk-Jan Dijk and Charles Czeisler in the 1990s put human subjects on enforced 28-hour sleepwake cycles, in constant dim light and with other time cues suppressed, for over a month. Because normal people cannot entrain to a 28-hour day in dim light if at all,[citation needed] this is referred to as a forced desynchrony protocol. Sleep and wake episodes are uncoupled from the endogenous circadian period of about 24.18 hours and researchers are allowed to assess the effects of circadian phase on aspects of sleep and wakefulness including sleep latency and other functions.[page needed]
Example Output: What time cycle did studies in 1938 and 1990s use on humans?
