Generative AI is AI that:
  1. only stores files
  2. only checks spelling
  3. only sorts data into groups
  4. creates new content such as text, images or music
2.
Is turning a rough sketch into a coloured image mainly a task for generative AI or conventional AI?

  2. rule-based automation
  3. generative AI
  4. conventional AI
3.

  3. 70%
  4. 40%
8.
What does “training data” mean?
  1. the large collection of examples a model learns from
  2. a hidden or visible mark showing content was made by AI

9.
What is generative AI? Give two examples of what it can create.
10.
Is each task for generative or conventional AI? (a) predicting tomorrow’s temperature (b) recommending a book from past reading
11.
Which kind of generative AI makes each? (a) a spoken voice reading out text (b) a short animated clip from a prompt
12.
A class checks 25 answers from an AI chatbot against the textbook, and 10 contain a wrong fact. (a) How many answers were fully correct? (b) What percentage is that?
13.
Explain each term: (a) training data (b) generative AI
14.
Which idea does each situation show: transparency, privacy, bias, misinformation or accountability? (a) A school checks AI-suggested marks before giving them to students. (b) A student says which parts of a project were drafted with an AI tool.
15.
A quiz shows 20 pictures, and students guess which are AI-generated. 5 of the pictures really are. A student marks every picture as AI-generated. (a) How many does the student get right? (b) What percentage is that?
16.
A training set has 200 images, and 90 show people over 60. (a) What percentage is that? (b) How many more images of people over 60 must be added so that they make up half of the set?
Section C — Word problems4 × 4 = 16 marks
17.
Explain how generative AI works in simple terms, and why it can make mistakes.
18.
A student asks a chatbot 20 questions for a project, and 8 answers turn out to contain a wrong fact. (a) What percentage of answers were wrong? (b) If 5 classmates each copied all 20 answers without checking, how many wrong facts would be copied in all? (c) Give one good habit when using AI answers.
19.

(a) How many pictures have no recorded age? (b) What percentage show children? (c) Why might pictures it makes of older people be less realistic?
20.
In a quiz, a student labels 50 pictures as AI-made or real. 35 pictures really are AI-made, and she labels 32 of those correctly; of the 15 real photos, she labels 15 correctly. (a) How many labels are correct? (b) What is her accuracy? (c) How many real photos did she wrongly call AI-made?

1(d) creates new content such as text, images or music—
2(c) generative AI—
3(c) text generation—
4(a) it may not know about recent events—
5(d) accountability—
6(a) 62.5%25 ÷ 40 × 100
7(b) 30%60 ÷ 200 × 100; a small share can lead to biased outputs
8(a) the large collection of examples a model learns from—
9AI that creates new content; e.g. text such as stories, and images from descriptions.—
10(a) conventional; (b) conventionalgenerative AI creates new content; conventional AI classifies or predicts
11(a) audio generation; (b) video generation—
12(a) 15; (b) 60%15 ÷ 25 × 100
13(a) the large collection of examples a model learns from (b) AI that creates new content such as text or images—
14(a) accountability; (b) transparency—
15(a) 5; (b) 25%every AI picture is right, every real one wrong: 5 ÷ 20 × 100
16(a) 45%; (b) 2090 ÷ 200 × 100; 90 + x = (200 + x) ÷ 2 gives x = 200 − 2 × 90
17It learns patterns from huge amounts of examples and produces new content that fits those patterns; it predicts what looks likely, not what is checked to be true, so it can be wrong.—
18(a) 40%; (b) 40; (c) e.g. check facts against a textbook or trusted source and say where AI was used8 ÷ 20 × 100; 8 × 5
19(a) 20; (b) 55%; (c) older people are a small share of the training data, so the model has fewer examples to learn from400 − 380; 220 ÷ 400 × 100
20(a) 47; (b) 94%; (c) 032 + 15; ÷ 50 × 100
