Question Discussion & Solution

The correct answer is A thin layer of silicon.

Key Points

• In computers, the chip is made up of a thin layer of silicon.
  • Computer chips are made of silicon, which is a semiconductor, and in order to make the most efficient use of it, chip manufacturers use sand that contains as much silicon as possible.
  • The mineral quartz is ideal for this purpose because its two main components are silicon and oxygen.
  • Silicon is used because it can be used as either an insulator (doesn't allow electricity to flow) or a semiconductor (allows a little flow of electricity).
  • This is important for making chips.
  • It is very, very cheap.
• Hence, option 2 is correct. 

Additional Information

• Silicon is used for electronic devices because it is an element with very special properties.
  • One of its most important properties is that it is a semiconductor.
  • This means that it conducts electricity under some conditions and acts as an insulator under others.
  • It is even the most common element in the Earth's crust. 
• Lady Ada Lovelace invented looping in computer programming​.
  • Lady Ada Lovelace wrote a complete plan describing the algorithm needed to calculate the Bernoulli numbers using two loops, demonstrating the bifurcation capabilities of the analytical machine, describing how to perform trigonometric operations that made use of variables.

Here the pattern is,

8 + 1² = 8 + 1 = 9

9 + 2² = 9 + 4 = 13

13 + 3² = 13 + 9 = 22 ¹ 27

22 + 4² = 22 + 16 = 38

Hence, 27 is the odd one out

The correct answer is Punishment shall not be less than seven years, but which may extend to ten years, and shall also be liable to fine.

• Under Section 370, whoever commits the offence of trafficking shall be punished with rigorous imprisonment for a term which shall not be less than seven years, but which may extend to ten years, and shall also be liable to fine.

​ Important Points

•  Section 370 -
  • ​Trafficking means whoever, for the purpose of exploitation, a. recruits b. transports c.harbours, d.transfers, or e. receives, a person or persons, by-
    • ​using threats,
    • using force, or any other form of coercion,
    • by abduction,
    • by practising fraud, or deception,
    • by abuse of power,
    • by inducement, including the giving or receiving of payments or benefits, in order to achieve the consent of any person having control over the person recruited, harboured, transported, transferred, or received, commits the offence of trafficking. 
• The expression "exploitation" shall include any act of physical exploitation or any form of sexual exploitation or practices similar to slavery, servitude, or the forced removal of organs.
• The consent of the victim is immaterial in the determination of the offence of trafficking.

The logic is,

In the first image, there are three and four-sided figures in the first column and four and three-sided figures in the second column.

In the second image, there are four and five-sided figures in the first column and three and two-sided figures in the second column.

In the third image, there is five-sided figure in the first column and only two lines in the second column.

So, we get that the side of the figure is increasing by one in both the figures of the column while a side is decreasing by one in both the figures of the second column. Thus, the third figure must be as follows:

Hence, option 4 is the correct answer.

• Apiculture is the technique of scientific rearing of honey bees in a specially designed wooden box.
• The essential elements for beekeeping are smoker, safety dress, moveable hive, honey extractor and hive tool.
• Sericulture is the process of rearing of silkworms to produce raw silk.
• Sericulture is the production of raw silk by means of raising caterpillars (larvae), those of the domesticated silkworm.
• Silk is a continuous filament within each cocoon.
