Primary General Studies, Media Literacy, Paper 1: verification, privacy and copyright
Ten items on how forwarding spreads a message, advertisement labels, password combinations, forwarding speed, finding the original source, reverse image search, personal data, copyright share and screen time.
Focus Forwarding spreads a message; advertisements must be labelled; longer passwords have more combinations; forwarding speed is the count divided by hours; verification means finding the source, checking a second trusted source and checking the date; photos can be edited, so use a reverse image search; a name, phone number, address and identity card number should stay private; permission is needed to use other people work; screen time should be limited.

03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 20 × 3 = 60 people. | Twenty people per round, so three rounds reach sixty people. |
| 2 | Look for an advertisement or sponsored label, and check whether it only praises the product. | Advertisements must be labelled, and one-sided praise is also a clue. |
| 3 | The 8-digit PIN, which has 10,000 times more combinations. | Longer passwords have more combinations and are harder to guess. |
| 4 | 1,200 ÷ 24 = 50 times. | The average rate is the total divided by the number of hours. |
| 5 | Find the original source and see who published it first. | A message with no traceable source should not be forwarded. |
| 6 | Use a reverse image search to see other versions or captions of the same picture. | Photos can be edited or mislabelled, so a reverse search helps find the original. |
| 7 | All 4 of them should not be posted publicly. | These four kinds identify a person, so publishing them carries risk. |
| 8 | 45 ÷ 180 × 100% = 25%. | Permission is needed to use another person work, whatever the share. |
| 9 | 28 ÷ 168 × 100% ≈ 16.7%. | Percentage is part divided by whole times one hundred, and a week has 168 hours. |
| 10 | No. Many forwards only show that a message spread widely, not that it is accurate. | Forward counts say nothing about accuracy, so verify the message yourself. |
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.
