Correct answer is option 'B'. Can you explain this answer?

Kiran Das answered
Pages
Pages are a necessary part of a book. They are the physical sheets on which the content of the book is printed. Without pages, a book would not be able to hold the information, stories, or pictures that it contains.

Importance of Pages in a Book
- Pages provide a structure for organizing the content of the book.
- They allow the reader to easily navigate through the book and find specific information.
- Pages are essential for holding the text, pictures, and other elements that make up the book.
- Pages also give the book its physical form and help in preserving the content for future reading.

Connection to the Underlined Word
In this case, the underlined word is "book." Pages are an integral part of a book, as they are where the content of the book is housed. Without pages, a book would not be able to exist in its traditional form. Therefore, pages are a necessary component of a book.

Dome

  • c)

  • d)
    Coppery
Correct answer is option 'A'. Can you explain this answer?

Palak Nambiar answered
Understanding the Term "Dome"
To identify the necessary part of the word "Dome," we need to explore its characteristics.
Definition of a Dome
- A dome is a rounded structure that resembles the upper half of a sphere.
- It is often used in architecture for roofs of buildings such as churches, mosques, and government buildings.
Analyzing the Options
- a) Rounded: This option directly describes the shape of a dome. Domes are inherently rounded structures, making this the most fitting choice.
- b) Geodesic: While some domes can be geodesic (constructed using a network of triangles), this term does not define a dome universally. It describes a specific type of dome.
- c) Governmental: This word refers to something related to government and does not pertain to the essential characteristics of a dome.
- d) Coppery: This option describes a color or material but does not relate to the shape or structure of a dome itself.
Conclusion
The word that most accurately represents a necessary part of the underlined word "Dome" is "Rounded." This is because the defining feature of a dome is its rounded shape, making option 'A' the correct answer.
