Read the passage about the Taj Falaknuma Palace library carefully and answer the following: On his very first day as librarian, which author wrote the reference book titled "How to paint grass" that Asif Husain found?

Introduction / Context:
This reading comprehension question is based on a descriptive passage about the Taj Falaknuma Palace library and the new librarian, Asif Husain. The aim is to check whether the learner can identify a specific factual detail from the passage, namely the name of the author of a particular reference book mentioned in the narrative.

Given Data / Assumptions:

• The passage describes the 101 seater dining table and the impressive library at the Falaknuma Palace.
• The library is done in rosewood and mahogany and has a high roof that imitates the one at Windsor Castle.
• The palace could not find a suitable librarian for many years until they appointed Asif Husain Arastu.
• On his first day as librarian, Asif Husain discovered a reference book titled "How to paint grass".
• The passage clearly states that this book is by Alfred East.

Concept / Approach:
This is a direct factual detail question. The correct method is to locate the relevant sentence in the passage and carefully read the exact wording. There is no inference or deep interpretation required. Good strategy involves scanning for the key phrase "How to paint grass" and then noting the author name that appears immediately with this title.

Step-by-Step Solution:
Step 1: Read the entire passage once to understand the overall setting of the Falaknuma Palace and its library. Step 2: Identify the portion of the passage that mentions the first day of work for the librarian, Asif Husain. Step 3: Focus on the sentence that states he found a reference book titled "How to paint grass". Step 4: Observe the exact wording that follows this title. The passage clearly says that the book is "by Alfred East". Step 5: Compare this name with the options given in the question and choose the option that matches exactly.

Verification / Alternative check:
To verify, a student can reread the sentence around the book title and check whether any other author is linked with this specific title. No other writer in the passage is associated with "How to paint grass". Mark Twain and Charles Dickens are famous authors, but the passage does not connect them to this book. Anuradha Naik is mentioned as a historian friend who points out the requirement for a librarian, not as the author of the reference book. Thus, Alfred East is confirmed as the correct answer.

Why Other Options Are Wrong:

• Alfred East: This matches the passage exactly and is therefore correct, not wrong.
• Anuradha Naik: She is a historian friend who informs Asif about the library vacancy, not the author of "How to paint grass".
• Mark Twain: A well known American writer, but his name does not appear connected to this reference book in the passage.
• Charles Dickens: Another famous author of English literature, but the passage does not mention him at all in relation to the Falaknuma Palace library.

Common Pitfalls:
Learners sometimes guess based on familiarity with names instead of checking the passage. Seeing well known authors like Mark Twain or Charles Dickens may tempt a student to choose them even though the passage does not connect them with the book. Another mistake is confusing the historian, Anuradha Naik, with the author because both names appear close together in the text. Careful reading and attention to the phrase "by Alfred East" prevent these errors.

Final Answer:
The author of the book "How to paint grass" mentioned in the passage is Alfred East.
