All wires are ropes.

Some ropes are steels.

(2) Some ropes are cables.

AOnly conclusion (1) follows

BOnly conclusion (2) follows

CNeither conclusion (1) nor (2) follows

DBoth conclusion (1) and (2) follows

Answer:

B. Only conclusion (2) follows

Read Explanation:

Using the exam-oriented syllogism convention (where the class mentioned in universal statements is assumed to exist):


  • All wires are cables

  • All wires are ropes

  • Some ropes are steels


Conclusion (1): Some steels are wires

Does not follow
There is no definite connection given between steels and wires.


Conclusion (2): Some ropes are cables

Follows
Since all wires are ropes and all wires are cables, the wires (assumed to exist) are common to both ropes and cables → some ropes are cables.


Only conclusion (2) follows
