Key Points

• Immoral Traffic (Prevention) Act
  • This Act may be called the Immoral Traffic (Prevention) Act, 1956.
  • It extends to the whole of India.

The correct answer is Sulphur.

• The sulphur is the eye irritating compound that is released when cutting onions.
• The syn-Propanethial-S-oxide is the chemical irritant produced by an onion.
• This chemical stimulates the eyes' lachrymal glands which release tears.
• Previously scientists used to blame enzyme alinase for the instability of substances in a cut onion.
• In 2002, a study in Japan proved that lachrymatory factor synthase is responsible for irritation of the eyes.

 Indus Valley Civilization

• Indus Valley Civilization was one of those early urban civilizations that were originated in 2300 BC and were developed in the river basins of Sutlej, Ravi, and Indus.
• Indus Valley Civilization peoples cultivate many crops such as Barley, Wheat, Melon seeds, and oil crops like Sesame, Mustard, and Dates. These were traded by farmers with other people. 
• The most typical Indus seal is square, with a set of symbols along the top, an animal in the centre, and one or more symbols at the bottom.  

Seals

• The unicorn is the most common motif on Indus seals and appears to represent a mythical animal that Greek and Roman sources trace back to the Indian subcontinent. A relatively long inscription of eight symbols runs along the top of the seal. Hence option 3 is correct.

• Archaeologists have discovered thousands of seals, mostly made of steatite, and occasionally of agate, chert, copper, faience and terracotta, with beautiful figures of animals, such as unicorn bull, rhinoceros, tiger, elephant, bison, goat, buffalo, etc.
• The realistic rendering of these animals in various moods is remarkable. The purpose of producing seals was mainly commercial.
• It appears that the seals were also used as amulets, carried on the persons of their owners, perhaps as modern-day identity cards. The standard Harappan seal was a square plaque 2×2 square inches, made from steatite.
• Every seal is engraved in a pictographic script which is yet to be deciphered. Some seals have also been found in ivory.
• They all bear a great variety of motifs, most often of animals including those of the bull, with or without the hump, the elephant, tiger, goat and also monsters.

The correct answer is Desktop.

Key Points 

• Desktop
  • The first screen which appears when windows are loaded is called Desktop.
  • As soon as we open the computer we come across the Windows welcome screen which displays many small pictures on the screen of the monitor.
    • This screen is known as the desktop.
  • The small pictures on the screen are known as icons.

Additional Information

• File Folder
  • ​A file is the common storage unit in a computer, and all programs and data are "written" into a file and "read" from a file.
  • A folder holds one or more files, and a folder can be empty until it is filled. 
• Recycling Bin
  • ​A recycling bin (or recycle bin) is a container used to hold recyclables before they are taken to recycling centers. 
  • Recycling bins exist in various sizes for use inside and outside homes, offices, and large public facilities.
• Recently Added Screen
  • ​A typical “Recently Added” section looks like at the top of the Start menu app list.
  • It's a small area that shows the names and icons of recently installed apps.

The correct answer is Sulphur Cycle

Key Points

• The sulphur reservoir is in the soil and sediments where it is locked in organic (coal, oil and peat) and inorganic deposits (pyrite rock and sulphur rock) in the form of sulphates, sulphides and organic sulphur.
• It is released by weathering of rocks, erosional runoff and decomposition of organic matter and is carried to terrestrial and aquatic ecosystems in a salt solution.
• The sulphur cycle is mostly sedimentary except two of its compounds, hydrogen sulphide (H2S) and sulphur dioxide (SO2), which add a gaseous component.
• Sulphur enters the atmosphere from several sources like volcanic eruptions, combustion of fossil fuels (coal, diesel etc.), from the surface of the ocean and gases released by decomposition.
• Atmospheric sulphur dioxide is carried back to the earth after being dissolved in rainwater as weak sulphuric acid (acid rain).
• Sulphur bound in a living organism is carried back to the soil, to the bottom of ponds and lakes and seas through excretion and decomposition of dead organic material.
