Question Discussion & Solution

Key Points

General attributes of a good language:

• Clarity, simplicity, and unity: provides both a framework for thinking about algorithms and a means of expressing those algorithms 
• Cost of use: program execution, program translation, program creation, and program maintenance Orthogonality: every combination of features is meaningful
• Naturalness for the application: program structure reflects the logical structure of the algorithm
• Support for abstraction: program data reflects problem being solved 
• Ease of program verification: verifying that the program correctly performs its required function
• Programming environment: external support for the language
• Portability of programs: transportability of the resulting programs from the computer on which they are developed to other computer systems

Hence the correct answer is Non-portability.

The correct answer is Jhalawar.

Key Points

• Chandrabhaga Fair
  • It is organized in Kartik Month (October and November).
  • It is organized in the Jhalawar districts of Rajasthan.
  • It is organized in the honor of the Chandrabhaga River.

The correct answer is from gypsum.

Key Points

• Plaster of Paris is manufactured by heating gypsum at 423K or 150°C/300° F.
• On heating gypsum at 423 K, it loses water molecules and becomes calcium sulfate hemihydrate.
• This product is known as the plaster of Paris.

Additional Information 

• Characteristics of Gypsum Plaster:
  • Plaster of Paris is usually a white dry plaster powder.
  • It can be effectively worked with metal apparatuses or even abrasive sheets and can be shaped as per the requirements.
  • The strength of plaster of Paris is not as strong as other compounds and it often requires external support when a large amount is used.
  • It is often applied in the form of a quick-setting paste with water. 

The correct answer is Fermentation. Key Points

• The name of the process which converts milk into curd is lactic fermentation and in this process, the lactose sugar of the milk is converted into lactic acid by lactic acid bacteria.
• The acid thus produced curdles the milk and gives it a sour taste.
• During the fermentation process, lactose fermenting bacteria utilize lactose of milk to gain energy.
• Fermentation is an enzyme-catalyzed, the metabolic process whereby organisms convert starch or sugar to alcohol or an acid anaerobically releasing energy.
• The science of fermentation is called “zymology”.
• Types of Fermentation
  • ​Homo fermentation: only one type of product formation
  • Hetero fermentation: more than one product formed
• Examples of Products Formed by Fermentation
  • ​Beer, Wine, Yogurt, Cheese, Certain sour foods containing lactic acid, including sauerkraut, kimchi, and pepperoni.
  • Bread leavening by yeast.
  • Sewage treatment.
  • Some industrial alcohol production
