03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | about 915 days, roughly two and a half years | Foundation and land reform belong to different stages: the law came only in 1950 and completion waited until late 1952. |
| 2 | 1825 days, that is 5.0 years | The First Plan covered the five years 1953 to 1957, and the Second was drafted only after 1957 overfulfilled it. |
| 3 | about 116 days apart, both within the same year | The Leap was set in May 1958 and the commune resolution in August, so the two campaigns overlapped in one summer and compounded each other. |
| 4 | 3796 days, that is 10.4 years, not a round ten | The decade label is shorthand; the real span exceeds ten years, and day counts expose the rounding. |
| 5 | 974 days to the hydrogen bomb; 2016 days to the satellite | The three milestones span six years, showing very different technical thresholds. |
| 6 | about 387 days, more than a year | What began as rectification turned into a campaign that ran into 1958 and shaped cadres and intellectual policy for years. |
| 7 | 4210 days, about 11.5 years | The suspension covered the whole Cultural Revolution, with recommended worker-peasant-soldier students replacing examinations until the winter of 1977. |
| 8 | 1012 days, about three years | The war ran nearly three years through five campaigns, trench warfare and talks; an armistice is not a peace treaty. |
| 9 | 214 days apart | With Washington, 1972 brought only a communique and formal ties waited until 1979, while Tokyo established relations in September 1972. |
| 10 | it misses growth with sharp swings: output fell in 1967-68, yet the Third Front and local industry expanded in the 1970s | Look at sectors and years rather than one aggregate; no growth and growth with swings are different findings. |
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.
Errors thrive on vagueness; compute the days and the sense of time becomes precise.Tutor Registration →
