Previous post on validity and sound arguments on the 365DaysOfPhilosophy site. 

Are the following valid (V) or invalid (I) and then sound (S) or unsound (U)?

1. Most ballet dancers are over 5 feet tall. Joanna is a ballet dancer, therefore Joanna is five feet tall.
2. Joanna is a woman. If Joanna is a woman, then she is tall. Therefore Joanna is a tall woman.
3. The Queen is a woman, therefore Albert is a blonde, then Albert is a blonde.
4. If unicorns are real, then at least there’s one real fantasy creature. Unicorns are real, therefore at least one fantasy creature is real.
