S1 English: Comparatives and Superlatives (Paper 4: mistake clinic)
Paper four targets past mistakes: leg pairs of insects, the group of bats and whales, percentage denominators and scientific names.
Direct answers Write the classifying feature first, then check the denominator is right.

03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 6 legs, that is 3 pairs | Three pairs of legs means six legs, one of the defining features of insects. |
| 2 | No, a spider belongs to the arachnids | The number of leg pairs is the key: insects have 3 pairs while spiders have 4. |
| 3 | 20.0 Percentage points | Eight divided by forty times one hundred gives 20.0 percentage points. |
| 4 | 16 species | Two to the power four equals 16. |
| 5 | The mammals | Both breathe with lungs and suckle their young. |
| 6 | 20.0 Percentage points | Forty-five divided by two hundred twenty-five times one hundred gives 20.0 percentage points. |
| 7 | The genus starts with a capital letter and the whole name is in italics | The genus is capitalised, the epithet is lower case, and the whole name is italic. |
| 8 | Spores | Ferns have spore cases on the fronds and release spores when ripe. |
| 9 | Family is broader, species is the finest rank | One family holds many genera and a genus holds species, so family is much broader. |
| 10 | No. Common names vary by region, so the scientific name decides | One common name may cover different organisms, and only the scientific name names one species exactly. |
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.
With all four done, go back to the chapter page and revise the three parts of a closed circuit plus three safety habits.Tutor Registration →
