Primary General Studies, Media and Information Literacy, Paper 4: sharing chains, deepfakes and chart traps
Ten items on the exponential spread of a repost, yearly screen hours, suspicious email shares, GB to MB conversion, deepfake flaws, truncated chart axes, clickbait, a four-step check and the digital footprint.
Focus Multiplying by the same number each round is a power, so 3 to the 4th gives 81; four hours a day for 365 days is 1,460 hours or about 60.8 whole days; 5 out of 100 is 5% yet one email can do damage; 12 GB times 1,024 gives 12,288 MB; deepfakes show unnatural blinking and mismatched lighting or edges; an axis that starts above zero exaggerates gaps; a sensational headline is clickbait; the four checks are source, date, full text and cross-reference; deleting a post does not erase the footprint.

03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 3 to the power 4 = 81 people. | Each round multiplies by the same number, so the growth is a power. |
| 2 | 4 × 365 = 1,460 hours, which is about 60.8 days. | Divide the yearly hours by 24 to see how many days that equals. |
| 3 | 5 ÷ 100 × 100% = 5%. | A small share is not safe, because one email is enough to cause harm. |
| 4 | 12 × 1,024 = 12,288 MB. | Storage and data units usually step by 1,024 rather than 1,000. |
| 5 | Unnatural blinking and lip movement, and lighting or edges of the face that do not match the background. | Tools keep improving, so still compare against the original source. |
| 6 | Check where the axis starts. If it does not begin at zero, the visual gap is inflated, so read the actual values. | The same data can look completely different with another axis. |
| 7 | It is clickbait; read the article and trace the original report before judging. | Headlines are written by editors and may not reflect the main point. |
| 8 | Find the original source, check the date, read the full text, then cross-check against other reliable reports. | If any of the four steps fails, hold off on sharing. |
| 9 | It may already have been screenshotted, reposted or archived, so deleting removes only your own copy. | Thinking before posting works far better than deleting afterwards. |
| 10 | Reading only the headline spreads misinformation, and sharers share responsibility for the error. | Sharing is an action and also a judgement. |
04 What to do after marking
- After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
- Repeat the same item two days later; move to the next paper only when both attempts are correct.
- Parents only need the answer and note columns; there is no need to explain every item.
