Statements: This book 'Z' is the only book which focuses its attention to the problem of poverty in India between 1950 and 1980.
Conclusions:
1. There was no question of poverty before 1950.
2. No other book deals with poverty in India during 1950 to 1980
Answer: B
The phrase 'only book' in the statement makes II implicit. However, nothing about the state of poverty before 1950 can be deduced from the statement. So, I does not follow.
