• The First Official Census in India was done in 1881 AD under Lord Rippon.
  • It was called First synchronised census.

The correct answer is Brahmi.​

• The Edicts of Ashoka are in total 33 inscriptions written on the Pillars, boulders, and cave walls of the Mauryan Period, during the reign of the Emperor Ashok that are dispersed throughout the Indian Sub-continent covering India, Pakistan, and Nepal.
  • Inscriptions found in the eastern parts of the Mauryan empire are written using the Brahmi script in Magadhi language.
  • While in the western parts of the empire, the script used is Kharoshti, written in Prakrit. To add to the variety, one extract in the Edict 13 is written in Greek and Aramaic.
• A notable thing in these inscriptions is, that Ashoka refers to himself in many of these inscriptions as “Devampiyaa” which means “Beloved of the Gods” and “King Piyadassi.”
• The world came to know of these details of the Mauryan empire and Ashoka when the edicts and inscriptions were decoded by British Archaeologist James Princep. 

Key Points

• These edicts have mentioned that Buddhism as a religion had reached as far as the Mediterranean under the Ashokan reign.
• Many Buddhist monuments had been created in the wide-spread area.
• In these edicts, Buddhism and the Buddha are also mentioned.
• But primarily these edicts focus more on social and moral precepts rather than the religious practices (or the philosophical dimension) of Buddhism during Ashoka’s reign.

UPDATE -  the number of wetlands in India has increased to 42.

Key Points

The Ramsar Convention:

• Ramsar Convention, 1971: on Wetlands of International Importance especially as Waterfowl Habitat is an international treaty for the conservation and sustainable use of wetlands
• The Convention on Wetlands is an intergovernmental treaty that provides the framework for the conservation and wise use of wetlands and their resources.
• The Convention was adopted in the Iranian city of Ramsar in 1971 and came into force in 1975. Since then, almost 90% of UN member states, from all the world’s geographic regions, have acceded to become “Contracting Parties”.
• India is a party to the Ramsar Convention. India signed under it on 1st February 1982.
• Chilika Lake (Orissa) and Keoladeo National Park (Rajasthan) were recognized as the first Ramsar Sites of India
• Sundarbans is the largest Ramsar Site of India
• On 2nd February 2021, India’s first Centre for Wetland Conservation and Management has been set up in Chennai.
• There are 42 wetlands in India that have international importance and hence recognized as the Ramsar Sites in India. Ramsar Sites are wetlands that have international importance.

Three Pillars:

• ​Under the “three pillars” of the Convention, the Contracting Parties commit to:
  • work towards the wise use of all their wetlands;
  • designate suitable wetlands for the list of Wetlands of International Importance (the “Ramsar List”) and ensure their effective management;
  • cooperate internationally on transboundary wetlands, shared wetland systems, and shared species.

The Montreux record:

• The Montreux Record is a register of wetland sites on the List of Wetlands of International Importance where changes in ecological character have occurred, are occurring, or are likely to occur as a result of technological developments, pollution, or other human interference.
• It is maintained as part of the Ramsar List.

The correct answer is Calcium Carbonate.

Key Points

• The chief component of the nacre that constitutes the pearl is aragonite (CaCO₃).
• Nacre also contains a small amount of conchiolin, a hornlike organic substance (albuminoid) that is the main constituent of the mollusc's outer shell.
• Pearl also contains Magnesium Carbonate(MgCO₃) along with Calcium Carbonate.

Additional Information

• Calcium carbonate is a common substance found in rocks as the minerals calcite and aragonite and is the main component of eggshells, snail shells, seashells, and pearls. 
• The Molar Mass of Calcium Carbonate is 100.0869 g/mol.
• Melting point: 825 °C.

% → modulus operator

printf() function

The printf() function is used for output. It prints the given statement to the console.

Analysis:-

m = m%(m*3)

Calculation:

m = 23 mod (23 × 3)

m = 23 mod 69  

m = 23 

Note:

Assignment operator associativity is right to left.

Printf statement will print the value of m as 23. (Output would be 23).

Confusion PointsHere 23 mod 69 means. 23 is divided by 69. That's why 23 is the answer. For better clarity, you can run the above program and check.
