Statements: Some trunks are chests. All chests are crates. No crate is a barrel.
Which one of the following conclusions definitely follows?
Show the answer and explanation
Correct answer: C
Explanation
Every chest is a crate and no crate is a barrel, so no chest is a barrel.
The trunks that are chests are therefore not barrels: some trunks are not barrels. This follows.
Trunks that are not chests may be barrels, so 'No trunk is a barrel' is not certain. 'Some barrels are chests' contradicts 'No chest is a barrel'. 'All crates are chests' reverses an All.
The conclusion that definitely follows is: Some trunks are not barrels.
Worth noting
Upgrading the Some-not to a full 'No trunk is a barrel' is the tempting mistake.
