Problem: Gamal Abdel Nasser:

Because of his ability to motivate nationalistic passions, "men, women, and children wept and wailed in the streets" after hearing of his death, according to Nutting. The general Arab reaction was one of mourning, with thousands of people pouring onto the streets of major cities throughout the Arab world. Over a dozen people were killed in Beirut as a result of the chaos, and in Jerusalem, roughly 75,000 Arabs marched through the Old City chanting, "Nasser will never die." As a testament to his unchallenged leadership of the Arab people, following his death, the headline of the Lebanese Le Jour read, "One hundred million human beings—the Arabs—are orphans." Sherif Hetata, a former political prisoner and later member Nasser's ASU, said that "Nasser's greatest achievement was his funeral. The world will never again see five million people crying together."

How many people marched in Jerusalem?

A: 75,000


Problem: Light is the signal by which plants synchronize their internal clocks to their environment and is sensed by a wide variety of photoreceptors. Red and blue light are absorbed through several phytochromes and cryptochromes. One phytochrome, phyA, is the main phytochrome in seedlings grown in the dark but rapidly degrades in light to produce Cry1. Phytochromes B–E are more stable with phyB, the main phytochrome in seedlings grown in the light. The cryptochrome (cry) gene is also a light-sensitive component of the circadian clock and is thought to be involved both as a photoreceptor and as part of the clock's endogenous pacemaker mechanism. Cryptochromes 1–2 (involved in blue–UVA) help to maintain the period length in the clock through a whole range of light conditions.
What signals plants to synchronize their internal clocks?

Answer: Light


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Lancashire is smaller than its historical extent following a major reform of local government. In 1889, the administrative county of Lancashire was created, covering the historical county except for the county boroughs such as Blackburn, Burnley, Barrow-in-Furness, Preston, Wigan, Liverpool and Manchester. The area served by the Lord-Lieutenant (termed now a ceremonial county) covered the entirety of the administrative county and the county boroughs, and was expanded whenever boroughs annexed areas in neighbouring counties such as Wythenshawe in Manchester south of the River Mersey and historically in Cheshire, and southern Warrington. It did not cover the western part of Todmorden, where the ancient border between Lancashire and Yorkshire passes through the middle of the town.
What county lies north of Lancashire?
A: unanswerable


Context and question: By 6000 BCE predynastic Egyptians in the southwestern corner of Egypt were herding cattle and constructing large buildings. Subsistence in organized and permanent settlements in predynastic Egypt by the middle of the 6th millennium BCE centered predominantly on cereal and animal agriculture: cattle, goats, pigs and sheep. Metal objects replaced prior ones of stone. Tanning of animal skins, pottery and weaving were commonplace in this era also. There are indications of seasonal or only temporary occupation of the Al Fayyum in the 6th millennium BCE, with food activities centering on fishing, hunting and food-gathering. Stone arrowheads, knives and scrapers from the era are commonly found. Burial items included pottery, jewelry, farming and hunting equipment, and assorted foods including dried meat and fruit. Burial in desert environments appears to enhance Egyptian preservation rites, and dead were buried facing due west.
What made Egyptian preservation rites difficult?
Answer: unanswerable


Question: Herds of red and fallow deer also roam freely within much of Richmond and Bushy Park. A cull takes place each November and February to ensure numbers can be sustained. Epping Forest is also known for its fallow deer, which can frequently be seen in herds to the north of the Forest. A rare population of melanistic, black fallow deer is also maintained at the Deer Sanctuary near Theydon Bois. Muntjac deer, which escaped from deer parks at the turn of the twentieth century, are also found in the forest. While Londoners are accustomed to wildlife such as birds and foxes sharing the city, more recently urban deer have started becoming a regular feature, and whole herds of fallow and white-tailed deer come into residential areas at night to take advantage of the London's green spaces.
Is there an answer to this question: Why are herds of deer starting to enter residential areas in London?

Answer: to take advantage of the London's green spaces


QUES: The City Planning Commission, tasked with guiding growth and development of the city, has divided the city into 18 planning districts as part of the Philadelphia2035 physical development plan. Much of the city's 1980 zoning code was overhauled from 2007–2012 as part of a joint effort between former mayors John F. Street and Michael Nutter. The zoning changes were intended to rectify incorrect zoning mapping that would streamline future community preferences and development, which the city forecasts an additional 100,000 residents and 40,000 jobs to be added to Philadelphia in 2035.

When was the 1980 zoning code revamped?
What is the answer?
ANS:
2007–2012
