Question Discussion & Solution

Key Points

• Protection of Women from Domestic Violence Act, 2005:
  • Domestic Violence means:
    • “Physical abuse" includes hurt of any kind. Assault, criminal intimidation and criminal force. Hence statement 1 is correct.
    • “Sexual abuse" such as the conduct of a sexual nature such as forced sexual intercourse, forcing the aggrieved person to watch pornography or other obscene material
    • “Verbal and emotional abuse" such as Accusation/aspersion on character or conduct. An insult for not bringing dowry, Insult for not having a male child. Hence statement 2 is Correct.
    • "Economic abuse" such as not providing money for maintaining a woman or her children. Not providing food, clothes, medicine. etc, Forcing woman out of the house. Hence statement 4 is Correct.
  • Non-sharing of household work, noncaring attitude for children, unhealthy habits of living. late coming etc. (of the male partner) is not directly covered under this act. Hence Statement 3 is Incorrect.

The correct answer is ​Heat is absorbed.

Key Points

•  When ice is converted into water heat is absorbed by the ice, so the molecules of ice increase their energy and convert into water. Hence option A is correct.
• Additional Information
• The conversion of ice into water is an example of melting. If you took out the ice cubes from the freezer and placed them in a warm room, the ice would absorb energy from the warmer air around them. This absorbed energy would facilitate them to overcome the force of attraction holding them together, enabling them to slip out of the fixed position that they held as ice. The process in which solids change to a liquid is called melting. The melting point is the temperature at which a solid changes to a liquid. 
• The static water is converted to ice It means when the water is converted into ice its potential energy decreases. 
• If we compare the kinetic and potential energy of the water vapor, water and ice then water vapor has the most kinetic as well as potential energy as compared to water and ice.
• This is because the particle of water vapor is free to move and they can move more vigorously. Please note that kinetic energy is associated with moving objects whereas potential energy is associated with a static object. 

The correct answer is ALGORITHM.

Key Points

• An algorithm is a specific procedure for solving a well-defined computational problem.
• The development and analysis of algorithms are fundamental to all aspects of Computer Science like AI, databases, graphics, networking, OS, etc.
• Algorithm development is more than just programming.
  • It requires an understanding of the alternatives available for solving a computational problem.
  • It includes the hardware, networking, programming language, and performance constraints that accompany any particular solution.

Additional Information

• An official language comprising a collection of instructions that produce different kinds of output is a programming language.
• In computer science, programming languages are used to implement algorithms.
• Most of the languages of programming consist of computer instructions.

The correct answer is Esterification.

Key Points

• Esterification -
  • Acid + Alcohol = Ester
  • It is a chemical reaction that forms at least one ester.
  • Esters are produced when acids are heated with alcohol.

Additional Information

• Crystallization -
  • The process of obtaining a pure solid in the form of crystals from a saturated solution is called crystallization.
  • In crystallization, the solution is first evaporated to separate a solid from the solution.
  • When the solution becomes very concentrated, the solution is cooled slowly by stopping evaporation, causing crystals to form.
• Saponification -
  • The saponification of a fat or oil is done by using NaOH solution for the hot process.
  • Saponification to the sodium salt of myristic acid takes place with NaOH in water.
  • Soap is formed by a chemical reaction by heating an aqueous solution of vegetable oil or fat and caustic soda or caustic potash, and glycerol is liberated.

The logic followed is:

The statement talks about the company X which has decided to increase the price of its car by 10%.

conclusion I and conclusion II may or may not follow because we can not tell from the given statement that what other companies will do if company X increases the price of cars.

But other companies can't increase the price and decrease the price of cars at the same time.

They will increase or decrease the price of cars.

Hence the correct answer will be Either I or II follows.

Additional Information

• If there are two or more sentences that are used to frame a statement, then, the sentences must be interrelated, and mutual contradiction should be there.
• Do not look for truthful notions. The information provided in the statement is the only requirement for a student to answer the question. No assumptions must be made.
• Read the statement carefully and look for keywords that are common between the statement and the conclusions
• If there is more than one conclusion that is applicable to the statement, students must ensure that the conclusions they opt for have some relation with each other.
