Why is the Sino-Soviet split a turning point?

Once the socialist bloc was no longer monolithic, Washington had room to improve ties with Beijing, and triangular diplomacy took shape.

Why are the war days more than three years?

Three years is only the difference between the years; subtracting the actual dates adds the extra months at each end.

Tutor Prep Guide · Primary English

Paper 3 moves from Korea and the Sino-Soviet split through Resolution 2758 to the 1991 dissolution, counting war days, life-expectancy gains and years between milestones, and ends on the 1949 UN-seat error.

Reminders　Subtract real calendar dates, treat founding and recognition as separate events, and read proxy wars through the superpowers.

03　Answers and one-line notes

#	Answer	One-line note
1	The Korean War	North Korean forces crossed the 38th parallel and a UN force backed the South, turning the Cold War hot by proxy.
2	Their split became open and Moscow withdrew all its advisers	Ideological dispute plus national interest turned the two socialist giants from allies into rivals.
3	It gave the People’s Republic the China seat at the United Nations	The resolution also removed the Taiwan representation, a turning point in Chinese diplomacy.
4	1991	After the failed August coup the republics declared independence one after another and the Soviet flag came down at the end of the year.
5	1 128 days	Subtracting the real dates gives 1128 days, a good deal more than three calendar years.
6	29 years	1989 minus 1960 is 29, so it took almost three decades to repair the alliance.
7	10 years	1979 minus 1969 is ten years; the border clash actually pushed both sides towards contact.
8	27 years	67 minus 40 is 27; longer lives reflect better health care and food supply during the Cold War years.
9	42 years	1991 minus 1949 is 42, the whole span in which the relationship went from alliance to rivalry and back to normalisation.
10	1949 is the founding; the UN seat came only in 1971	Founding a state and winning international recognition are separate events twenty-two years apart.

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.
