KeyError: 'answer' When Accessing Answer Key in score_one_result

[abdelazizmohamad11]

When completing the questions for the "science" section, the program throws a KeyError: 'answer' in the score_one_result function. This error occurs because the JSON data for some questions does not contain an "answer" key. Without this key, the program is unable to evaluate the user’s response and calculate the score.
