The non fiction book titled 100 Things to Know and Debate Before You Vote, which guides citizens about elections and democracy, is written by which author?

Introduction / Context:
Books that discuss voting, democracy and public debate are very relevant in civics and current affairs based examinations. The title 100 Things to Know and Debate Before You Vote suggests a guide for citizens to think critically before participating in elections. This question checks whether aspirants can correctly associate this book with its author, Hindol Sengupta, who is known for writing on politics, economics and society.

Given Data / Assumptions:

• The title of the book is 100 Things to Know and Debate Before You Vote.
• The content deals with issues voters should understand and discuss.
• Four options list different Indian public intellectuals and writers.
• We assume standard bibliographic information about this non fiction work.

Concept / Approach:
The concept being tested is again books and authors, but with a focus on contemporary political writing. The author of this book is Hindol Sengupta, a journalist and writer who has authored several works on Indian politics and economics. The other options are also writers and commentators on Indian public life, which makes the question slightly tricky unless the exact pairing is known.

Step-by-Step Solution:
Step 1: Note the focus of the title on voting and debate, which indicates a modern democratic context. Step 2: Recall that 100 Things to Know and Debate Before You Vote is authored by Hindol Sengupta. Step 3: Shashi Tharoor has written many books such as Why I Am a Hindu and An Era of Darkness, but not this one. Step 4: Ramachandra Guha is known for historical and biographical works like India After Gandhi, not this guide style book. Step 5: P Chidambaram has written on the economy and policy, but he is not associated with this particular title. Step 6: Since Hindol Sengupta is the widely cited author of this book, he is the correct choice.

Verification / Alternative check:
To verify, one can consult publisher catalogues or book seller descriptions for 100 Things to Know and Debate Before You Vote. These consistently list Hindol Sengupta as the author. The book is often mentioned in news and interviews related to elections and voter awareness, where his name is linked directly to the work, confirming the attribution.

Why Other Options Are Wrong:
Shashi Tharoor: Although a prolific author and parliamentarian, he has not written a book with this exact title.
Ramachandra Guha: Focuses mainly on history, biography and cricket writing, not on this specific voter focused guide.
P Chidambaram: Known more for economic commentary and political roles rather than this particular book.

Common Pitfalls:
Because all the names are linked to politics or commentary, candidates sometimes pick a more famous figure rather than the correct one. Another pitfall is vaguely remembering that a parliamentarian wrote a book on voting and then guessing wrongly. Careful revision of book titles and authors, especially for contemporary non fiction on politics, helps in selecting the right answer under exam pressure.

Final Answer:
The book 100 Things to Know and Debate Before You Vote is written by Hindol Sengupta.
