Problem: Gamal Abdel Nasser:

Nasser made secret contacts with Israel in 1954–55, but determined that peace with Israel would be impossible, considering it an "expansionist state that viewed the Arabs with disdain". On 28 February 1955, Israeli troops attacked the Egyptian-held Gaza Strip with the stated aim of suppressing Palestinian fedayeen raids. Nasser did not feel that the Egyptian Army was ready for a confrontation and did not retaliate militarily. His failure to respond to Israeli military action demonstrated the ineffectiveness of his armed forces and constituted a blow to his growing popularity. Nasser subsequently ordered the tightening of the blockade on Israeli shipping through the Straits of Tiran and restricted the use of airspace over the Gulf of Aqaba by Israeli aircraft in early September. The Israelis re-militarized the al-Auja Demilitarized Zone on the Egyptian border on 21 September.

How did the Egyptian people feel about Nasser's response to the attack?
---
A: a blow to his growing popularity


Problem: Physical exercise, particularly continuous aerobic exercises such as running, cycling and swimming, has many cognitive benefits and effects on the brain. Influences on the brain include increases in neurotransmitter levels, improved oxygen and nutrient delivery, and increased neurogenesis in the hippocampus. The effects of exercise on memory have important implications for improving children's academic performance, maintaining mental abilities in old age, and the prevention and potential cure of neurological diseases.
What causes decreased oxygen and nutrient delivery?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Many species of birds are economically important. Domesticated and undomesticated birds (poultry and game) are important sources of eggs, meat, and feathers. Songbirds, parrots, and other species are popular as pets. Guano (bird excrement) is harvested for use as a fertilizer. Birds prominently figure throughout human culture. About 120–130 species have become extinct due to human activity since the 17th century, and hundreds more before then. Human activity threatens about 1,200 bird species with extinction, though efforts are underway to protect them. Recreational birdwatching is an important part of the ecotourism industry.
How many species of birds have become extinct as a result of human activity?
A: 120–130

Question: The National Autonomous University of Mexico (UNAM), located in Mexico City, is the largest university on the continent, with more than 300,000 students from all backgrounds. Three Nobel laureates, several Mexican entrepreneurs and most of Mexico's modern-day presidents are among its former students. UNAM conducts 50% of Mexico's scientific research and has presence all across the country with satellite campuses, observatories and research centres. UNAM ranked 74th in the Top 200 World University Ranking published by Times Higher Education (then called Times Higher Education Supplement) in 2006, making it the highest ranked Spanish-speaking university in the world. The sprawling main campus of the university, known as Ciudad Universitaria, was named a World Heritage Site by UNESCO in 2007.
Is there an answer to this question: What worldwide ranking does UNAM hold?

Answer: 74th


Black labor played a crucial role in Miami's early development. During the beginning of the 20th century, migrants from the Bahamas and African-Americans constituted 40 percent of the city's population. Whatever their role in the city's growth, their community's growth was limited to a small space. When landlords began to rent homes to African-Americans in neighborhoods close to Avenue J (what would later become NW Fifth Avenue), a gang of white man with torches visited the renting families and warned them to move or be bombed.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was NW Fourth Avenue previously called?
Ah, so..
unanswerable
