03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | It ran from 18 to 22 December 1978, five days in all, not a single day. | Count both the first and the last day: 22 minus 18 is 4, plus one makes five. |
| 2 | Eighteen households, not twenty. | Eighteen households is the fixed figure for this episode; do not round it up to twenty. |
| 3 | Only four in 1980: Shenzhen, Zhuhai, Shantou and Xiamen. Hainan became the fifth in 1988, an increase of 25 per cent. | Separate the year from the count: (5 minus 4) divided by 4 is 25 per cent. |
| 4 | Fourteen coastal open cities, not zones; with the four zones that made eighteen open points. | Coastal open cities and special economic zones are different statuses; zones enjoy fuller tax and approval powers. |
| 5 | 617 days. | Subtract the dates rather than guessing years, and remember 1980 was a leap year with 29 February. |
| 6 | About 10,370 times, not a hundred times. | Convert both figures to the same unit before dividing so the orders of magnitude stay right. |
| 7 | An 18 point gap, saving 3.6 million yuan on 20 million yuan of profit. | A percentage-point gap is a subtraction: 33 minus 15 is 18, not 33 divided by 15. |
| 8 | A gain of 240,000 jin, an increase of 50 per cent. | Take the per-mu gain of 200 jin times 1,200 mu, and get the percentage from 200 over 400. |
| 9 | The Third Plenary Session was in 1978; the market-economy goal was set at the 14th Party Congress in 1992, after Deng Xiaoping southern tour. | The 1978 plenum shifted the work focus; the market-economy formulation came at the 1992 congress. |
| 10 | Gradual reform had costs of a different kind: dual-track pricing bred rent-seeking and official profiteering, and the 1988 price breakthrough fuelled inflation and panic buying. | Not collapsing is not the same as bearing no cost; separate short-run stability from long-run distortion. |
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.
