Problem: Gamal Abdel Nasser:

On 29 October 1956, Israeli forces crossed the Sinai Peninsula, overwhelmed Egyptian army posts, and quickly advanced to their objectives. Two days later, British and French planes bombarded Egyptian airfields in the canal zone. Nasser ordered the military's high command to withdraw the Egyptian Army from Sinai to bolster the canal's defenses. Moreover, he feared that if the armored corps was dispatched to confront the Israeli invading force and the British and French subsequently landed in the canal city of Port Said, Egyptian armor in the Sinai would be cut off from the canal and destroyed by the combined tripartite forces. Amer strongly disagreed, insisting that Egyptian tanks meet the Israelis in battle. The two had a heated exchange on 3 November, and Amer conceded. Nasser also ordered blockage of the canal by sinking or otherwise disabling forty-nine ships at its entrance.

What did the British and French air forces bomb?
---
A: Egyptian airfields in the canal zone


Problem: The first high-brightness blue LED was demonstrated by Shuji Nakamura of Nichia Corporation in 1994 and was based on InGaN. In parallel, Isamu Akasaki and Hiroshi Amano in Nagoya were working on developing the important GaN nucleation on sapphire substrates and the demonstration of p-type doping of GaN. Nakamura, Akasaki and Amano were awarded the 2014 Nobel prize in physics for their work. In 1995, Alberto Barbieri at the Cardiff University Laboratory (GB) investigated the efficiency and reliability of high-brightness LEDs and demonstrated a "transparent contact" LED using indium tin oxide (ITO) on (AlGaInP/GaAs).
What substance did Barbieri use in his work with low-brightness LED?

Answer: unanswerable


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
A 2009 Cochrane review concluded that thiazide antihypertensive drugs reduce the risk of death (RR 0.89), stroke (RR 0.63), coronary heart disease (RR 0.84), and cardiovascular events (RR 0.70) in people with high blood pressure. In the ensuring years other classes of antihypertensive drug were developed and found wide acceptance in combination therapy, including loop diuretics (Lasix/furosemide, Hoechst Pharmaceuticals, 1963), beta blockers (ICI Pharmaceuticals, 1964) ACE inhibitors, and angiotensin receptor blockers. ACE inhibitors reduce the risk of new onset kidney disease [RR 0.71] and death [RR 0.84] in diabetic patients, irrespective of whether they have hypertension.
What were RRE drugs used with?
A: unanswerable


Context and question: On 14 January 1858, an Italian refugee from Britain called Orsini attempted to assassinate Napoleon III with a bomb made in England. The ensuing diplomatic crisis destabilised the government, and Palmerston resigned. Derby was reinstated as prime minister. Victoria and Albert attended the opening of a new basin at the French military port of Cherbourg on 5 August 1858, in an attempt by Napoleon III to reassure Britain that his military preparations were directed elsewhere. On her return Victoria wrote to Derby reprimanding him for the poor state of the Royal Navy in comparison to the French one. Derby's ministry did not last long, and in June 1859 Victoria recalled Palmerston to office.
Where was Orsini from?
Answer: Britain


Question: The oldest known fossil among the Eutheria ("true beasts") is the small shrewlike Juramaia sinensis, or "Jurassic mother from China", dated to 160 million years ago in the Late Jurassic. A later eutherian, Eomaia, dated to 125 million years ago in the Early Cretaceous, possessed some features in common with the marsupials but not with the placentals, evidence that these features were present in the last common ancestor of the two groups but were later lost in the placental lineage. In particular:
Is there an answer to this question: What do Juramaia have in common with placentals?

Answer: unanswerable

According to the Office for National Statistics, at the 2001 census there were over a million black people in the United Kingdom; 1% of the total population described themselves as "Black Caribbean", 0.8% as "Black African", and 0.2% as "Black other". Britain encouraged the immigration of workers from the Caribbean after World War II; the first symbolic movement was those who came on the ship the Empire Windrush. The preferred official umbrella term is "black and minority ethnic" (BME), but sometimes the term "black" is used on its own, to express unified opposition to racism, as in the Southall Black Sisters, which started with a mainly British Asian constituency, and the National Black Police Association, which has a membership of "African, African-Caribbean and Asian origin".
In 2001 how many black people lived in the UK?
A:
over a million black
