User: Classify each of the following as either a true statement or a false statement: 
1. Albert Einstein was a Chinese mathematician that lived in the 19th and 20th century.
2. Pigs are not mammals.
3. This question contains four statements that need classification.
Assistant: Statement number 1 is mostly false, since Albert Einstein was neither Chinese or a mathematician. He was a German theoretical physicist. However, he did in fact live during the 19th and 20th centuries.

Statement number 2 is false. Pigs are in fact mammals. 

Statement number 3 is false. This question actually contained 3 statements.
