Serological methods are highly sensitive, specific and often extremely rapid tests used to identify microorganisms. These tests are based upon the ability of an antibody to bind specifically to an antigen. The antigen, usually a protein or carbohydrate made by an infectious agent, is bound by the antibody. This binding then sets off a chain of events that can be visibly obvious in various ways, dependent upon the test. For example, "Strep throat" is often diagnosed within minutes, and is based on the appearance of antigens made by the causative agent, S. pyogenes, that is retrieved from a patients throat with a cotton swab. Serological tests, if available, are usually the preferred route of identification, however the tests are costly to develop and the reagents used in the test often require refrigeration. Some serological methods are extremely costly, although when commonly used, such as with the "strep test", they can be inexpensive.

What methods are highly sensitive, specifc and rapid tests used to identify microorganisms?
Answer: Serological


Problem: Egyptian music is a rich mixture of indigenous, Mediterranean, African and Western elements. It has been an integral part of Egyptian culture since antiquity. The ancient Egyptians credited one of their gods Hathor with the invention of music, which Osiris in turn used as part of his effort to civilise the world. Egyptians used music instruments since then. Contemporary Egyptian music traces its beginnings to the creative work of people such as Abdu El Hamouli, Almaz and Mahmoud Osman, who influenced the later work of Sayed Darwish, Umm Kulthum, Mohammed Abdel Wahab and Abdel Halim Hafez whose age is considered the golden age of music in Egypt and the whole Middle East and North-Africa. Prominent contemporary Egyptian pop singers include Amr Diab and Mohamed Mounir.
What is more contemporary Egyptian Pop Singer?
The answer is the following: Amr Diab and Mohamed Mounir


The events of the Franco-Prussian War had great influence on military thinking over the next forty years. Lessons drawn from the war included the need for a general staff system, the scale and duration of future wars and the tactical use of artillery and cavalry. The bold use of artillery by the Prussians, to silence French guns at long range and then to directly support infantry attacks at close range, proved to be superior to the defensive doctrine employed by French gunners. The Prussian tactics were adopted by European armies by 1914, exemplified in the French 75, an artillery piece optimised to provide direct fire support to advancing infantry. Most European armies ignored the evidence of the Russo-Japanese War of 1904–05 which suggested that infantry armed with new smokeless-powder rifles could engage gun crews effectively. This forced gunners to fire at longer range using indirect fire, usually from a position of cover.
What was the French 75 optimised to directly support?
advancing infantry


Input: Hyderabad
The HMWSSB regulates rainwater harvesting, sewerage services and water supply, which is sourced from several dams located in the suburbs. In 2005, the HMWSSB started operating a 116-kilometre-long (72 mi) water supply pipeline from Nagarjuna Sagar Dam to meet increasing demand. The Telangana Southern Power Distribution Company Limited manages electricity supply. As of October 2014, there were 15 fire stations in the city, operated by the Telangana State Disaster and Fire Response Department. The government-owned India Post has five head post offices and many sub-post offices in Hyderabad, which are complemented by private courier services.

Along with dealing with sewerage and the water supply, what is one other thing the HMWSSB regulates?
Output: rainwater harvesting


Input: Article: Depleted uranium is also used as a shielding material in some containers used to store and transport radioactive materials. While the metal itself is radioactive, its high density makes it more effective than lead in halting radiation from strong sources such as radium. Other uses of depleted uranium include counterweights for aircraft control surfaces, as ballast for missile re-entry vehicles and as a shielding material. Due to its high density, this material is found in inertial guidance systems and in gyroscopic compasses. Depleted uranium is preferred over similarly dense metals due to its ability to be easily machined and cast as well as its relatively low cost. The main risk of exposure to depleted uranium is chemical poisoning by uranium oxide rather than radioactivity (uranium being only a weak alpha emitter).

Now answer this question: What kind of uranium is sometimes used to shield radioactive materials in containers?

Output: Depleted


Problem: The Crimean War marked the ascendancy of France to the position of pre-eminent power on the Continent,:411 the continued decline of the Ottoman Empire, and the beginning of a decline for Tsarist Russia. As Fuller notes, "Russia had been beaten on the Crimean peninsula, and the military feared that it would inevitably be beaten again unless steps were taken to surmount its military weakness." The Crimean War marks the demise of the Concert of Europe, the balance of power that had dominated Europe since the Congress of Vienna in 1815, and which had included France, Russia, Austria and the United Kingdom.
The Crimean war marked the end of what dominant European power?
The answer is the following:
Concert of Europe
