Logical Reasoning - Statement and Assumption - Discussion

Discussion Forum : Statement and Assumption - Section 2 (Q.No. 5)
Directions to Solve

In each question below is given a statement followed by two assumptions numbered I and II. You have to consider the statement and the following assumptions and decide which of the assumptions is implicit in the statement.

Give answer

  • (A) If only assumption I is implicit
  • (B) If only assumption II is implicit
  • (C) If either I or II is implicit
  • (D) If neither I nor II is implicit
  • (E) If both I and II are implicit.


Statement: Today I must satisfy myself only by looking at a pink headed duck in an encyclopaedia.


  1. Pink headed ducks are as good as extinct now.
  2. People refer to encyclopaedia to know only about things which do not exist now.

Only assumption I is implicit
Only assumption II is implicit
Either I or II is implicit
Neither I nor II is implicit
Both I and II are implicit
Answer: Option
Since the narrator talks of satisfying himself by just looking at a picture in encyclopaedia, it means that pink headed ducks are not to be seen alive. So, I is implicit. But II does not follow from the statement and is not implicit.

Assumption 2 must be the answer. To satisfy himself the author is in search of pink headed duck in Encyclopedia.

RIA said:   6 years ago
It is saying "I must satisfy myself".

I think 2 should be the answer -People refer to the encyclopaedia to know only about things which do not exist now.

Statement is specific to the author but assumption 1 is generalized one and assumption have no relevance with the statement.

I also thinks that answer could be D i.e. neither follows because in the statement it is not return that the pink head duck are extinct. And second statement, says that people usually see encyclopedia for animals which are extinct. So, none follows.

^ correct. And there may be other ways he can satisfy himself. But he will only choose to read the encyclopedia.

There may be many other reasons that the duck cannot be seen today, other than it being extinct.
