Problem: Infection:

Complex serological techniques have been developed into what are known as Immunoassays. Immunoassays can use the basic antibody antigen binding as the basis to produce an electro - magnetic or particle radiation signal, which can be detected by some form of instrumentation. Signal of unknowns can be compared to that of standards allowing quantitation of the target antigen. To aid in the diagnosis of infectious diseases, immunoassays can detect or measure antigens from either infectious agents or proteins generated by an infected organism in response to a foreign agent. For example, immunoassay A may detect the presence of a surface protein from a virus particle. Immunoassay B on the other hand may detect or measure antibodies produced by an organism's immune system that are made to neutralize and allow the destruction of the virus.

What type of signal do immunoassays produce?
---
A: electro - magnetic or particle radiation

Problem: The Blitz:

Nevertheless, it was radar that proved to be critical weapon in the night battles over Britain from this point onward. Dowding had introduced the concept of airborne radar and encouraged its usage. Eventually it would become a success. On the night of 22/23 July 1940, Flying Officer Cyril Ashfield (pilot), Pilot Officer Geoffrey Morris (Observer) and Flight Sergeant Reginald Leyland (Air Intercept radar operator) of the Fighter Interception Unit became the first pilot and crew to intercept and destroy an enemy aircraft using onboard radar to guide them to a visual interception, when their AI night fighter brought down a Do 17 off Sussex. On 19 November 1940 the famous RAF night fighter ace John Cunningham shot down a Ju 88 bomber using airborne radar, just as Dowding had predicted.

What concept eventually became successful?
---
A: airborne radar

Problem: Antibiotics:

Common forms of antibiotic misuse include excessive use of prophylactic antibiotics in travelers and failure of medical professionals to prescribe the correct dosage of antibiotics on the basis of the patient's weight and history of prior use. Other forms of misuse include failure to take the entire prescribed course of the antibiotic, incorrect dosage and administration, or failure to rest for sufficient recovery. Inappropriate antibiotic treatment, for example, is their prescription to treat viral infections such as the common cold. One study on respiratory tract infections found "physicians were more likely to prescribe antibiotics to patients who appeared to expect them". Multifactorial interventions aimed at both physicians and patients can reduce inappropriate prescription of antibiotics.

What is a way of improperly using rest for those traveling?

A: unanswerable

Problem: Ministry of Defence (United Kingdom):

The MoD has since been regarded as a leader in elaborating the post-Cold War organising concept of "defence diplomacy". As a result of the Strategic Defence and Security Review 2010, Prime Minister David Cameron signed a 50-year treaty with French President Nicolas Sarkozy that would have the two countries co-operate intensively in military matters. The UK is establishing air and naval bases in the Persian Gulf, located in the UAE and Bahrain. A presence in Oman is also being considered.

What did Oman sign with France?

A:
