Statements: D**X, F @ Y, D $ F
Conclusions: I. X @ Y II. Y # D

Options

A. If only I is true
B. if only conclusion II is true
C. if either conclusion I or II is true
D. if either I nor II is true

Answer

A

Explanation

Statements: `D lt X, F ge Y, D gt F`
Conclusions: I `X ge Y` II. `Y le D`
Combining `F ge Y` and `D gt F` we get `D gt F ge Y` so that `D gt Y` follows. So, II does not follow. Now, `D gt Y` and `D lt X` give `X gt D gt Y` follows but it is not the same as `X ge Y`. So, I does not follow.
