Question

under what condition could the convention no longer be enforced?
a a member state denounces the convention
b all but 15 member states denounce the convention
c the convention is over ten years old
d a member state commits an act of genocide

Explanation:

The question asks under what condition a convention could no longer be enforced. A convention relies on sufficient member state participation to maintain enforceability. If all but 15 member states denounce it, the remaining participation is too limited to sustain enforcement, unlike single-state denunciation (A), age (C), or a single state’s act (D), which do not eliminate the convention’s operational base.

Answer:

B. all but 15 member states denounce the Convention
