    display: flex;
    flex-wrap: wrap;
    width: 100%;
  }
  
  /* Force each item to be exactly 50% width */

    width: 50% !important;
    flex: 0 0 50%;
    box-sizing: border-box;

  /* Ensure items have consistent spacing */
  .question-answer-outer {
    margin: 5px;

  .question-mc {
    display: flex;
    flex-wrap: wrap;
  }
