How to play two animations simultaneously one after another ?

what I did is, I use the animation.playqueued but I cant make it work and i dont know why, what happens is both animation will play at the same time, but what I want is after I press a button, and plays the animation, another animation will automatically play after the first one finishes so here's the code

 private void HandleAnswer(int answer) {
  
          if (answer == 1)
         {
  
          ShowIncorrect = false;
                         ShowCorrect = true;
          Poop = false;
  
          animation.PlayQueued("Wrong answer",QueueMode.PlayNow);  
         Enemy.animation.PlayQueued("ENMattck",QueueMode.CompleteOthers);
          NextQuestion(); 
        }
  
         else { 
          ShowIncorrect = true;
           ShowCorrect = false;
          Poop = false;
  
  
          animation.PlayQueued ("Wrong answer",QueueMode.PlayNow);  
          Enemy.animation.PlayQueued("ENMattck", QueueMode.CompleteOthers);
  
        }
     }
