1. The problem involves calculating the ages or durations related to historical figures based on given years. 2. For each person, we calculate the age or duration by subtracting the earlier year from the later year. 3. Example for Aguinaldo: - Duration from 1899 to 1901: $$1901 - 1899 = 2$$ years (not 12, so likely a typo in the original data). - Age calculation: $$19614 - 1869$$ seems incorrect; assuming a typo, if it meant 1961 - 1869, then age is $$1961 - 1869 = 92$$ years. 4. For Quezon: - Duration from 1935 to 1944: $$1944 - 1935 = 9$$ years. - Age calculation: $$1944 - 1878 = 66$$ years. 5. For Laurel: - Duration from 1913 to 1945: $$1945 - 1913 = 32$$ years. - Age calculation: $$1945 - 1891 = 54$$ years. 6. For Osmeña: - Duration from 1944 to 1946: $$1946 - 1944 = 2$$ years. - Age calculation: $$1961 - 1878 = 83$$ years. 7. For Roxas: - Duration from 1946 to 1948: $$1948 - 1946 = 2$$ years. 8. For Quirino: - Duration from 1948 to 1953: $$1953 - 1948 = 5$$ years. 9. For Garcia: - Duration from 1961 to 1965: $$1965 - 1961 = 4$$ years. 10. For Macapagal: - Duration from 1935 to 1961: $$1961 - 1935 = 26$$ years. Summary: The calculations involve simple subtraction to find durations or ages. No graph is requested or applicable here.
