Question Discussion & Solution

The correct answer is Lead and Tin.

Key Points

• Soldering is the process of joining two metal objects together by a third soft metal alloy which is called solder.
• Solder is a metal alloy that melts at a lower temperature than the metals being soldered.
• A commonly used alloy is solder, which is an alloy of tin (Sn) and lead (Pb).
• The alloy of tin-lead solder is a mixture of 63% tin and 37% lead. 63/37 solder melts at 183°C.
• So, Alloy of tin (Sn) and lead (Pb) is used for welding electrical wire together.

Additional Information

• Element Tin (Sn) belongs to Group 14 of the periodic table.
  • Atomic Number - 50
  • Atomic Mass  - 118.710 amu.
• Element Lead (Pb) belongs to Group 14.
  • Atomic Number - 82
  • Atomic Mass - 207.2 amu.

The correct answer is Folk Dance.

Key Points

• Dancer Kalbelia Gulabo Sapera's tale is one of perseverance in the face of societal pressure.
• Gulabo was awarded the Padma Shri in 2016 for his efforts to popularise Rajasthan's Sapera dance tradition, which he has promoted in over 165 countries.
• She was a participant in the recently concluded Jaipur Literature Festival 2021, a woman whose storey is worth hearing.
• Gulabo's indomitable spirit protected her from a destiny that regularly befalls girl children in the nomadic group of kalbelias, an abjectly poor population on the outskirts of civilization.

Important Points

• Kalbelia is a snake-charming tribe from Rajasthan, India's the Thar Desert.
• Men and women both do dance, which is an important element of their culture.
• The Daliwal and Mewara are the two main groups of Kalbelias. In ancient times, the Kalbelias were known to wander about a lot.
• Catching snakes and trading snake venom is their traditional occupation.

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.

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 Trash

Key Points

• The Trash folder is where any emails have been deleted.
• This folder also indicates the mail which has been automatically deleted, are sent.
• The Trash folder will empty every time we log out of Message Center, and all of the messages will be permanently deleted.
• If we delete an e-mail from your inbox, it will initially be put into the Trash folder.
• The e-mail will only be permanently deleted if we delete it in the Trash folder or empty the trash, or if the e-mail's storage time has expired.
• Permanently deleted e-mail cannot be recovered.
• The default storage time for an email in the Trash folder is 1 day.
• We can customize the storage time for an email in the Trash folder.
• It is present at the left below the compose window in the email window.
