Conclusions:
I. K # S
II. Y @ M
III.T # M
IV.Y @ K

  • A.None is true
  • B.Only I is true
  • C.Only II is true
  • D.Only III is true
  • E.Only IV is true

Answer: A

Correct answer: None is true

This set’s code reads \(\$\) as \(\ge\), \(@\) as \(>\), \(\#\) as \(<\), \(\&\) as \(=\) and \(*\) as \(\le\). The statements become \( T \le Y \), \( S < M \), \( Y \ge S \) and \( M > K \). Drawn out, this is two loose fragments joined only at S: T and Y stand above S, while M stands above S as well and K below M. Nothing runs from one fragment through to the other in a single direction.

I. \( K < S \): K and S both sit below M, so their order is free. Not determined.

II. \( Y > M \): Y and M both sit above S. Not determined.

III. \( T < M \): T is only bounded above, by Y, and Y itself is unordered against M. Not determined.

IV. \( Y > K \): Y stands above S and K below M, and the two are three links apart with a reversal between them. Not determined.

None of the four follows. Every failure here is the same one - two elements attached to a common third from the same side.
