Show answer & explanation

Correct answer: B

Given statements:

  • A > B

  • D ≤ E

  • C ≥ F = G

  • B ≤ C = D

Conclusions to test:

  • Conclusion I: B ≥ G

  • Conclusion II: E ≥ G

Reasoning:

  1. From C ≥ F = G we get F = G and hence C ≥ G.

  2. From B ≤ C = D we get C = D and B ≤ C.

  3. From C = D and D ≤ E we deduce C ≤ E.

  4. Combining C ≥ G and C ≤ E gives E ≥ G.

Conclusion

  • Conclusion II (E ≥ G) follows, as shown above.

  • Conclusion I (B ≥ G) does not follow. A counterexample satisfying all given statements is: G = 5, C = D = 6, B = 1, E = 7; here B ≥ G is false while all original statements hold.
