input question: Question: "What else should be watched for?" Context: "Shortness of breath occurs when the damage to the heart limits the output of the left ventricle, causing left ventricular failure and consequent pulmonary edema. Other symptoms include diaphoresis (an excessive form of sweating), weakness, light-headedness, nausea, vomiting, and palpitations. These symptoms are likely induced by a massive surge of catecholamines from the sympathetic nervous system, which occurs in response to pain and the blood flow abnormalities that result from dysfunction of the heart muscle. Loss of consciousness (due to inadequate blood flow to the brain and cardiogenic shock) and sudden death (frequently due to the development of ventricular fibrillation) can occur in MIs." Answer:???
output answer: Other symptoms include diaphoresis (an excessive form of sweating), weakness, light-headedness, nausea, vomiting, and palpitations

Question: "The top is held in place with?" Context: "Inner and outer vestibules lead to the octagonal chapter house, which is of exceptional architectural purity. It is built in a Geometrical Gothic style with an octagonal crypt below. A pier of eight shafts carries the vaulted ceiling. To the sides are blind arcading, remains of 14th-century paintings and numerous stone benches above which are innovatory large 4-light quatre-foiled windows. These are virtually contemporary with the Sainte-Chapelle, Paris." Answer:
----
Answer: eight shafts

Q: Question: "what is the abbreviation of the organization the state profit from?" Context: "Presently, the Central African Republic has active television services, radio stations, internet service providers, and mobile phone carriers; Socatel is the leading provider for both internet and mobile phone access throughout the country. The primary governmental regulating bodies of telecommunications are the Ministere des Postes and Telecommunications et des Nouvelles Technologies. In addition, the Central African Republic receives international support on telecommunication related operations from ITU Telecommunication Development Sector (ITU-D) within the International Telecommunication Union to improve infrastructure." Answer:
A: ITU

Question: Question: "What was the original direction of the cannons?" Context: "Unveiled in 1888, Royal Arsenal's first crest featured three cannon viewed from above, pointing northwards, similar to the coat of arms of the Metropolitan Borough of Woolwich (nowadays transferred to the coat of arms of the Royal Borough of Greenwich). These can sometimes be mistaken for chimneys, but the presence of a carved lion's head and a cascabel on each are clear indicators that they are cannon. This was dropped after the move to Highbury in 1913, only to be reinstated in 1922, when the club adopted a crest featuring a single cannon, pointing eastwards, with the club's nickname, The Gunners, inscribed alongside it; this crest only lasted until 1925, when the cannon was reversed to point westward and its barrel slimmed down." Answer:
Answer: northwards

[Q]: Question: "What relationship to the road did the new tracks have?" Context: "Within the city there have been two tram networks in operation. A proposal to develop a horse-drawn tram (linking the city's railway termini) was made by American George Francis Train in the 1860s, and implemented in 1872 by the Cork Tramway Company. However, the company ceased trading in 1875 after Cork Corporation refused permission to extend the line, mainly because of objections from cab operators to the type of tracks which although they were laid to the Irish national railway gauge of 5 ft 3in protruded from the road surface.[citation needed]" Answer:
****
[A]: protruded from the road

Problem: Given the question: Question: "What is not simple?" Context: "QED vacuum has interesting and complex properties. In QED vacuum, the electric and magnetic fields have zero average values, but their variances are not zero. As a result, QED vacuum contains vacuum fluctuations (virtual particles that hop into and out of existence), and a finite energy called vacuum energy. Vacuum fluctuations are an essential and ubiquitous part of quantum field theory. Some experimentally verified effects of vacuum fluctuations include spontaneous emission and the Lamb shift. Coulomb's law and the electric potential in vacuum near an electric charge are modified." Answer:
++++++++++++++++++++++++++++++++
The answer is:
QED vacuum
