Facts

Show reasoning

I followed this chain of reasoning:

I know from locally stored knowledge that:
Sun Yat-sen is a person ([fact: ["18242707@trueknowledge.com"]])

November 12th 1866 is the birthdate of Sun Yat-sen ([fact: ["18242704@trueknowledge.com"]])

By calculation (generator: ["timepoint_sum@trueknowledge.com"]) I know that:
November 12th 1879 is the timepoint sum of November 12th 1866 and 13 years

November 12th 1886 is the timepoint sum of November 12th 1866 and 20 years

By calculation (generator: ["teenager@trueknowledge.com"]) I know that:
Fact 1: Sun Yat-sen is a teenager

Fact 1 is true for November 12th 1879 - November 12th 1886

I know from locally stored knowledge that:
Fact 2: Rutherford B. Hayes is a US president ([fact: ["1153832@trueknowledge.com"]])

Fact 2 is true for March 4th 1877 - March 4th 1881 ([fact: ["130968820@trueknowledge.com"]])

Therefore (generator: ["distinct_interleave@trueknowledge.com"]):
US president is not a distinct class from entity that is capable of deliberate action

By calculation (generator: ["overlap1@trueknowledge.com"]) I know that:
March 4th 1877 - March 4th 1881 is overlapping with November 12th 1879 - November 12th 1886

I know from locally stored knowledge that:
Fact 3: Chester A. Arthur is a US president ([fact: ["123991964@trueknowledge.com"]])

Fact 3 is true for September 19th 1881 - March 4th 1885 ([fact: ["130968794@trueknowledge.com"]])

By calculation (generator: ["overlap1@trueknowledge.com"]) I know that:
September 19th 1881 - March 4th 1885 is overlapping with November 12th 1879 - November 12th 1886

I know from locally stored knowledge that:
Fact 4: Stephen Grover Cleveland is a US president ([fact: ["123991970@trueknowledge.com"]])

Fact 4 is true for March 4th 1885 - March 4th 1889 ([fact: ["412632631@trueknowledge.com"]])

By calculation (generator: ["overlap1@trueknowledge.com"]) I know that:
March 4th 1885 - March 4th 1889 is overlapping with November 12th 1879 - November 12th 1886

I know from locally stored knowledge that:
Fact 5: James Garfield is a US president ([fact: ["127462395@trueknowledge.com"]])

Fact 5 is true for March 4th 1881 - September 19th 1881 ([fact: ["130967708@trueknowledge.com"]])

By calculation (generator: ["overlap1@trueknowledge.com"]) I know that:
March 4th 1881 - September 19th 1881 is overlapping with November 12th 1879 - November 12th 1886
