I wish if you could help me or give me an email of someone thant can help .
In a MCQ test where:
• each question has 4 choices [a,b,c,d]
• each question has only one correct answer (choice)
• there are 10 questions
• all questions have the same grade value (1 point, totalling 10 points)
4 students have taken this test and we have their grades:
• student1: [b, c, b, a, c, c, c, d, c, c] Grade: 7/10
• student2: [b, d, c, a, d, d, c, c, a, b] Grade: 6/10
• student3: [d, a, b, b, d, d, c, d, a, b] Grade: 5/10
• student4: [c, d, c, b, d, b, b, c, a, a] Grade: 3/10
From the informations above I need to write a prolog script that can determine the set of questions that are correct to get a 10/10 grade.
Thank you.
