S1 English: Comparatives and Superlatives (Paper 2: intermediate)
Paper two adds binomial naming, keys and comparison of ranks, with combinations and percentages.
Direct answers Draw branches for combinations, and write the numerator and denominator first for percentages.

03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | The genus name and the specific epithet | A scientific name is the genus name plus the specific epithet, written in italics. |
| 2 | 75.0 Percentage points | Eighteen divided by twenty-four times one hundred gives 75.0 percentage points. |
| 3 | A dichotomous key | Each step is a yes or no choice, so the method is called dichotomous. |
| 4 | 8 groups | Each extra feature doubles the combinations, and two to the power three is 8. |
| 5 | 40.0 Percentage points | Four hundred divided by one thousand times one hundred gives 40.0 percentage points. |
| 6 | 30 leaves | Fifty times 0.6 equals thirty. |
| 7 | 3.0 times | Forty-five divided by fifteen equals 3.0. |
| 8 | By spores | Ferns carry spore cases on the underside of fronds and release spores to reproduce. |
| 9 | Yes, one family may contain several genera | Family is a higher rank than genus, so one family can hold many genera. |
| 10 | No. One family can contain many different species | Shared features increase down the ranks, and species is the finest rank while family is much broader. |
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.
Then try paper three, using voltage and current to work out power and resistance.Tutor Registration →
