### Hands-on proof

**Given**: Groups such that is conjugacy-closed in and is conjugacy-closed in .

**To prove**: is conjugacy-closed in .

**Proof**: We need to show that if are conjugate in , then they are conjugate in . First, observe that since , are elements of conjugate in . Since is conjugacy-closed in , are conjugate in .

Thus, are elements of that are conjugate in . Since is conjugacy-closed in , the elements are conjugate in .
