Answer: Option A. -> Pigeon
Answer: (a)In the Second World War, pigeons were used less due to advances in telecommunication systems and radar, but they were still used in active service in Europe, India and Burma. The last pigeon messaging service was disbanded in 2006 after 60 years of active service in India.

Answer: Option B. -> Hassan – Karnataka
Answer: (b)
The Master Control Facility is a facility set up by the Indian Space Research Organisation (ISRO) in the city of Hassan in the Indian state of Karnataka. Established in 1982, this facility is responsible for monitoring and controlling the satellites launched by ISRO.
This was the only Master Control Facility of ISRO till another one was established in Bhopal in 2005. When ISRO wanted a control facility, it inspected various sites that were offered to it within India. ISRO chose Hassan as the location (Location on Google Maps) because it was free of noise and encountered less terrestrial transmission than other proposed sites.
Low interference was a must since the facility should be able to pick up even very weak signals from the satellite. Currently MCF controls the following 10 satellites: INSAT-2E, INSAT-3C, INSAT-3A, INSAT3E, INSAT-4A, INSAT-4B, INSAT-4CR KALPANA-1, GSAT-8 and GSAT-12.
On these 10 satellites, 8 are controlled from MCF Hassan and two are controlled from MCF Bhopal (INSAT-3C and INSAT-4CR.)

Answer: Option D. -> Japan
Answer: (d)The Greenhouse Gases Observing Satellite or GOSAT, also known as Ibuki (menaing breath in Japanese) is an Earth observation satellite and the world’s first satellite dedicated to greenhouse-gasmonitoring. It measures densities of carbon dioxide and methane from 56,000 locations on the Earth’s atmosphere.

Answer: Option D. -> Polar Satellite Launch Vehicle
Answer: (d)
The Polar Satellite Launch Vehicle (PSLV) is an expendable launch system developed and operated by the Indian Space Research Organisation (ISRO).
It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into sun-synchronous orbits, a service that was, until the advent of the PSLV, commercially viable only from Russia. PSLV can also launch small size satellites into geostationary transfer orbit (GTO).
The PSLV has launched 55 satellites/spacecraft (26 Indian and 29 Foreign Satellites) into a variety of orbits so far.
Note: The Polar Satellite Launch Vehicle, commonly known by its abbreviation PSLV, is an expendable launch system developed and operated by the Indian Space Research Organization (ISRO).
On Feb 15, 2017 PSLV-C37 Successfully Launches 104 Satellites in a Single Flight.

Answer: Option D. -> Chennai
Answer: (d)
The total annual external dose from sources in soil and cosmic rays in Mumbai, Kolkata, Chennai, Delhi and Bengaluru is 0.484, 0.81, 0.79, 0.70 and 0.825 milligray respectively. Gray is a unit for absorbed dose; when the radiation energy imparted to a kg of material is one joule, it is called a gray.
Since gray is very large, milligrays (one-thousandth of a gray), and microgray (one-millionth of a gray), are commonly used. Cosmic rays come from outer space. Their intensity at a place depends on the altitude. Cosmic rays alone contribute 0.28 milligrays at the first three cities as they are at sea level; the column of air helps to reduce their intensity.
At high altitudes, the protection from the column of air is less. The cosmic ray contributions are higher at 0.31 milligray and 0.44 milligray respectively at Delhi and Bengaluru as these cities are at altitudes of 216 metres and 921 metres. Air passengers receive 5 micrograys per hour from cosmic rays. Parts of Kerala and Tamil Nadu are high background radiation areas (HBRA) because of the presence of large quantities of monazite in the soil.
Thorium content in monazite ranges from 8-10.5 per cent. Researchers found that the radiation levels in 12 Panchayats in Karunagappally varied between 0.32 to 76 milligrays per year; the levels in 90 per cent of over 71,000 houses were more than one milligray per year.
